You will probably find AIS & AI Nikkors and better Series-E
Nikon lenses the best choice. Some AF-D Nikkors are quite
comfortable on the F3 and should not be over looked. If you own
AF Nikon SLR(s) and DSLR(s) you may want to mix and match auto
and manual focus lenses. Some AF Nikkors have a very short throw
(degrees of rotation) on the focus control and are not well
suited to manual focus. These should be avoided. Note that the F3
has no means for setting the lens aperture though the body so G
type Nikkors need not apply. With the use of stop down metering
and or a hand held light meter you can use many fine pre-AI
Nikkors.<br>

<em>Nikon new 85/1.4 (77 mm filter size) is excellent
lens for portraits. --Frank Skomial<br>
</em><br>
The problem with the 85/1.4D AF Nikkor is its close to
angle of view of a 135/2.8 AIS on film. This means the working
distance needs to be longer and so the perspective is flatter.
Head and shoulders images shot with an 85mm have an aloof feel to
them.<br>
<br>
The 58/1.2 AIS Noct on DX would make an excellent replacement for
an 85mm lens on 35mm film but for its price. The 60/2.8D AF Micro
and especially the 28 and 35~70/2.8 AF zooms would make an
excellent replacement for the 105/2.5 but the maximum aperture is
not large enough to blur backgrounds significantly so they dont
qualify.<br>
<br>
Nikon does not have full system of lenses for the DX formats and
they dont appear to be working on one. If they are they
should drop some hints at the very least. Time was when Japanese
companies planed for the long term and broke into new markets
with better products. They deferred quick profits for greater
market share and profits later on. Now I cant see that
Nikon management cares about the long term heath of the company.<br>
<br>
DX has been around long enough that Nikon management should have
a viable replacement for the 105/2.5 AIS. No f/2.8 lens can fill
this void on the DX formats. This is nothing less than
mismanagement. On top of this Nikon management is breaking about
ever rule of good customer relations. Its no wonder that
Nikon is loosing customers to Canon. I worry that Nikon will go
the way of Konica and Minolta. This might have been unthinkable
some years ago but Nikon is going for the short term and long
term health is ignored.<br>
<br>
If I were just starting in photography today Id buy Canon
for the very reasons that I started with Nikon in 1970.<br>

<em>I could never focus it fast enough or accurately
enough in any action situation, tons of fuzzy pics when I tried
to use it for a foot race I covered. --Neil Parker<br>
</em><br>
Just guessing but does this lens have a long throw on the focus
ring? I have an 80~200/4.0 AIS Nikkor and the throw is about 270
degree (three quarters turn) which make the 80~200/4.0 AIS quite
easy to focus accurately but very difficult to focus rapidly
particularly on a moving subject. The hand position may need to
be changed to continue focusing and this guarantees a lost shot
if the subject is in motion.<br>
<br>
If the zoom range is right the 75~150/3.5 Series-E is much easier
to focus on moving subjects. The 80~200/2.8D ED (with collar) is
a better choice for a manual focus camera than the 80~200/4.0 AIS
if the size and weight of the AF lenses is not too much.<br>
<br>
Obviously these lenses are quite short of 300mm but perhaps the
handling considerations are similar for the 80~200/4.0 AIS and
100~300/5.6 AIS. At 300mm and only f/5.6 I cant see the 100~300/5.6
AIS as a general purpose telephoto zoom. I can accept a 400/5.6
lens as the size, weight and especially the cost of faster 400mm
lenses is considerable.<br>

The 50/1.2 AIS (I dont own one) should give good ability to
blur backgrounds and its a pretty good focal length on DX
for a three-quarters portrait. Its similar in angle of view
to a 78 to 80mm lens on 24x36mm depending on the specific DX DSLR.
Id give the lens a spin. I think Id like one what
based on what Ive read here at PHOTO.NET and Bjorn Rorslett
give it a decent review here...<br>
<br>
<a href="http://www.naturfotograf.com/lens_norm.html"

<br>
<br>
What Id really like is a 70/1.4D ED-IF AF-S but such is not
made. If one ever is, and I think Nikon is slack not to make such
a lens, it will probably be a 70/1.4G ED-IF AF-S. Since I own
three cameras that accept G type lenses I could live with this
though I would not be overjoyed.<br>
<br>
If this 50/1.2 AIS can be had for a fair and reasonable price Id
grab it. If you find that you dont like the lens youll
probably have little trouble reselling it.<br>
<br>

<br>
Please, at about 360g and accepting a 52mm filter the 50/1.2 AIS
Nikkor is neither heavy nor large. It is certainly not heavy and
large compared to a 17~55/2.8G ED-IF AF-S DX Nikkor which weighs
about 755g and takes a 77mm filter. Neither lens is what Id
call petite but neither is a burden to use for general
photography. Although the latter is more than twice as heavy and
large it is extremely useful and many consider it their bread
and butter lens.<br>
<br>
The 50/1.8D AF and 45/2.8 P Nikkors are certainly smaller and
lighter but neither offers much ability to significantly blur
backgrounds to make the subject stand out. I own a 50/1.8 AF (Japan)
and a 50/1.8 AI Nikkor and I find neither well suited to
portraiture. For whatever reason I find the bokeh quite nice at f/2.8,
both lenses, but less so at f/1.8 and f/4.0. These lenses dont
come close on DX to replacing the 85/1.4 AIS, 85/2.0 AIS or 105/2.5
AIS on 24x36mm. The 85/1.8D AF, 85/1.4 AIS & AF-D and 85/2.0
AIS make a good replacment for the 135/2.8 AIS & AI on 35mm.
On there respective formats these lenses are very suitable for
tight head shots but less so for head and shoulders views.<br>
<br>
To get the perspective I want for a head and shoulders shot a 70mm
lens is great and the 28~70/2.8D ED-IF AF-S and 35~70/2.8D AF
often get recommended. If significant background blurring is not
desired they are both good choices. If blurring is desired then
neither is as f/2.8 at 70mm just doesnt do it.

<em>I know nothing about F stops or shutter speed but am
looking for a blurred backgroud and my subject sharp. --Joyce
Otazo<br>
</em><br>
Unfortunately the lens you own has too small a maximum aperture
to do much blurring of your background. What you need is a 50/1.4
to 85/1.8mm lens. The shorter the focal length the larger the
maximum aperture you need to get pleasingly blurred backgrounds.
The 50/1.8D AF Nikkor is often recommend but it doesnt blur
backgrounds much even wind open. I own a 50/1.8 AF Nikkor and Ive
tried. Its a nice sharp lens but a little short and does
not have a large enough maximum aperture.<br>
<br>
If you want to try shooting portraits with blurred background
with the lens you have forget the picture modes and use the
Aperture Preferred exposure mode. That the large capital "A"
on your Mode Dial. The camera will set the shutter speed for you.
There was a time when all of us here didnt know much of
anything about apertures. There is a time to learn. What you want
to do is zoom to about 85mm and set your aperture to the maximum.
Im guessing that will be about f/4.8. Try to get your
subject as far away from the background as possible. Im
going to repeat this as this gives the only hope for this
technique with your current lens. Move your subject as far as
possible from the background. I dont think this will give
you the results you want but its the best I can recommend.<br>
<br>
In truth selecting a lens for this kind of portrait is a problem
with Nikon DX DSLR(s). The lens Id like is a 70/1.4D ED-IF
AF-S and this lens just is not made by Nikon. Some use a 28~70/2.8D
ED-IF AF-S or 35~70/2.8D AF. I own the latter. The maximum
aperture of f/2.8 is not wide enough to do what my 105/2.5 AIS
did on 35mm film at 70mm. 70mm is a pleasing focal length for a
portrait on a Nikon DSLR but the maximum aperture is too small
with currently available lenses.<br>
<br>
The best lens I can recommend for you is the 85/1.8D AF Nikkor.
Its a little longer than Id like but f/1.8 at 85mm
will blur background quite easily. I own a Nikon D2H and an 85/2.0
AIS Nikkor. This is the lens I use for this type of photograph.<br>

<em>Oh my gosh...111 pages of instructions? I love my old
manual cameras! --Janet Cull<br>
</em><br>
If it make you feel any better you can use the F100 just like
your old manual cameras. I generally use my F100 and F5 in manual
exposure mode or aperture preferred mode. I often use manual
focus lenses and when I use AF lenses I mostly use them much like
manual focus. I disable the AF at the shutter release with custom
setting 4:1. I press the AF-ON button to focus and release to
lock. Its manual focus logic with AF ease and speed.<br>
<br>
When you get the PDF manual go over it and experiment. Decide
what custom settings to use and make a list of your personal
settings. If you do not change the custom settings here and there
you can really simplify the use of the camera. If you do change
them often youll never know what the cameras going to
do. This may not work for other but I set the custom settings and
leave them. With the F5 there are two banks of settings I use 4:1
in one and not in the other. About the only setting I may change
with the F100 is to set 4:1 back to 4:0 (default) when I want to
AF activated at the shutter release.<br>
<br>
One of the things that make a camera like the FM2n or F3 so nice
to work with is you know what the camera is going to do. With the
F3 you have aperture preferred and manual mode but you select
shutter speeds or set and release aperture preferred mode with
the same control. Tailoring the custom settings on an AF SLR or
DSLR and then leaving then alone can do the same thing.<br>
<br>
If an when you do experiment with custom settings be disciplined
very consistent and return everything to your preferred settings
before putting the camera away. The next time you shoot the
camera will perform just as you expect. I think youll get
as comfortable with your new F100 as with older camera like the
FE2, FM2n or F3/F3HP.<br>
<br>
Best,<br>
<br>
Dave Hartman.<br>
<br>
PS: Ill attach a custom settings chart for the F100. You
can easily edit the personal settings with a program like
Microsoft FrontPage Express. The version Im using came free
with Windows NT. It works fine under Windows 2000 and should work
under Windows XP. You can also edit the personal settings using
Notepad. Check it over as its never been professionally
proofread.

<em>Nikon keeps the lid on body serial numbering.
--Walter Schroeder<br>
</em><br>
Which is a major disservice to the customer. It probably has to
do with the gray marker. Maybe its just
paranoia. They seem to hold on to this information years after
products are discontinued.<br>
<br>
When I called Hasselblad for information needed to order a custom
eyepiece for an NC-2 Prism I asked about the age of my camera.
The tech guy asked me for the serial number then took a minute or
so and he told me the year and the month of manufacture. I wonder
why Hasselblad didnt care and Nikon does?<br>

Why dont you ask the store you are considering to show
records of when a particular camera was received. If they say
they wont or cant tell them you will buy elsewhere.
If they are convinced that you are a serious buyer they might. I
used to do business with a store that just tossed me their
wholesale catalogs. I bought from them in preference to a nearby
mail order store because of better service and an open account so
they didnt care. I think its worth a try.<br>

<em>Unfortunately no, this cannot be eliminated. Any
form of i-TTL flash will always use a preflash, there are no
exceptions (Nikons rules not mine). DHH<br>
</em><br>
Im sorry this is not clear. You cannot eliminate the
preflash with any form of TTL flash with your camera but no form
of manual flash will use a preflash. CLS or will always use a
preflash or series of them. You might have read between the lines
and figured this out. My suggestions above to use manual variable
flash and SC-17, 28 or 29 cord are specifically to eliminate the
troublesome preflash.<br>
<br>
I should have mentioned using manual exposure mode as aperture
preferred may cause problems with a slow shutter speeds or a Hi
warning. Its best to take full control of the shutter here.
I think you are using a D50. In that case your top flash sync
speed is 1/500 second (page 131 in your manual). When writing I
just ignored this as I would automatically use manual exposure
mode with manual flash.<br>
<br>
Im not sure how well the FV Lock (flash value) would work
with no bird at the feeder or flower. You might use the FV Lock
when your subject is at the feeder or flower and then wait for it
to return. The FV lock is a toggle, press to lock, press to
release. I own flash meters so Id prefer to do the job all
manual but you might fine the FV lock useful. <br>
<br>
The FV lock does not eliminate the preflash but it does separate
it from the event by pre-flashing well before the shot and locking
the flash exposure. Again its a toggle so you do it once and
then you are free to take many shot of the same subject and the
same flash to subject distance.<br>
<br>
Im sorry about the sloppiness above. Hope I didnt
mess up too much here.<br>

<em>Im open to any opinions for either of these
two. --Darla Love<br>
</em><br>
Darla, <br>
<br>
At todays prices do you need to chose? I recommend that you
buy both. <br>
<br>
I prefer the FM2n when using fast prime lenses in low light where
I will not be using flash. I particularly like the red LED +0-
meter display at night compared to the FE2s invisible
needle. <br>
<br>
If Im going to use flash or shooting in daylight I prefer
the FE2. In daylight the FE2s needle and flag meter display
is easy to use and exposure compensation is easy to achieve
without messing with the exposure compensation dial. <br>
<br>
When using flash with the FE2 you get standard TTL flash with any
Nikon SB-24, 25, 26, 28 and with the SB-800 (or 600). This means
the speedlight you buy for your DSLR will work great with the FE2.
If but only if you buy an SB-800 it will work with the FM2n also.
The SB-600 lacks an electronic eye on the face so it lacks Auto
Flash for non-TTL Flash cameras like the FM2n and F2As. The SB-800
offers Auto Flash for these and others.<br>

I agree with those who recommend the D200. I own a D2H and most
of my glass is manual focus AIS and AI. A couple of my lenses go
back to the mid and late sixties. I also like my AF-D glass and
wish I had more. I tend to prefer manual focus prime lenses and
auto focus zoom lenses. I mix and match.<br>
<br>
So how do you use AIS and AI Nikkors with the D200? If you use
center-weighted metering you just install them as you do on your
F3 and FM3a and start shooting.<br>
<br>
If you want to use matrix metering then you need to inform the
camera of the maximum aperture of your lens. You can do this two
ways. One is you set a custom setting and then use the Function
Button. You press the function button and roll the command dial
to set the focal length and roll the subcommand dial to set the
maximum aperture. The camera remember pairs of focal lengths and
apertures so if you only have one 105mm lens and it's a 105/2.5
then once the information is in the camera you select 105mm and
you start shooting. You can also set the non-CPU lens
data using the shooting menu.<br>
<br>
The procedures listed above for matrix metering are reasonably
easy and fast enough for most photography but for events
photography and PJ style photography I recommend AF and zoom lenses.<br>

<em>BTW, she is comparing the digital images to photos

</em><br>
This sounds like a job for the Curves Pallet in Photoshop. Try
pinning or dragging down the quarter tone slightly then drag up
the three-quarters tone a bit. This will increase the mid tone
contrast and also the mid tone saturation at the expense of shadow
and highlight contrast. Velvia 50 is not only a high saturation film
but also a high contrast film. Im sure this will give your
friend the look she wants. For best results shoot NEF.<br>

<em>Is there a way to eliminate this metering flash
while using iTTL? --Matt Adams<br>
</em><br>
By metering flash I believe you are referring to the
i-TTL Preflash used by the SB-600 and 800. Unfortunately no, this
cannot be eliminated. Any form of i-TTL flash will always use a
preflash, there are no exceptions (Nikons rules not mine).
You can check the upper left corner of the LCD panel on the SB-600
or 800. If you see a double lightning bolt there will be a
preflash. Note that neither of these speedlights will show a
feature or mode that is not available to the camera on which it
is installed. This is a good thing. It will save many mistakes.
If you see a mode offered by the flash, it's available to your
camera.<br>
<br>
If you are using on camera flash, switch to manual mode. Determine
the proper exposure before the event. Humming birds are fairly
predictable when feeding. I assume you are photographing them at
flowers or a hummingbird feeder. <br>
<br>
To get a shorter effective flash duration you can use manual,
variable power. For example the effective flash duration of the
SB-600 at 1/8 power is approximately 1/6,600 second. The
effective flash duration for 1/16 power is approximately 1/11,100
second. Please see page 88 in your SB-600 manual.<br>
<br>
Im quite sure that 1/8 and 1/16 power will not be enough
power for a proper exposure if the flash is on the camera. You
can move the flash closer to the subject by using an SC-17, 28 or
29 TTL cord and a light stand. By moving the flash closer to your
subject you make the inverse square law of light propagation work
for you. The closer the flash is to the subject the more intense
the light but also the distance from the light to the subject
becomes quite critical. Take measurements, take notes and be
precise. If you need more distance than one SC-17 cord allows you
can use up to three. You can also straiten an SC-17 TTL cord in
near boiling water.<br>
<br>
If you do not own light stands and are on a tight budget try to
find some used Smith-Victor steel light stands. These should be
quite inexpensive.<br>
<br>
I hope something here helps. Good luck!<br>
<br>

<em>Tell me guys, what can be wrong here?--Edward
Ng<br>
</em><br>
A focus error is the most plausible answer. There are a number of
other possibilities. The D100s viewfinder and focus screen
are not suitable for critical focus.<br>
<br>
When I test a lens on charts I use a DW-2, DW-4 or DW-31, 6x high
magnification waist level viewfinder. I focus with a 1,000 watt
quarts flood lamp then turn off all lights and make the exposure
with electronic flash with the camera set to B. This
eliminates focus errors to a considerable extent and it
eliminates vibrations so its as close to a pure test of the
lens as I can possibility do. In consideration of film flatness I
dont let the film sit in the camera and get kinked.
Considerable care is need in setting up the camera to assure that
it is perpendicular to the test target. My test film was Kodak
Tech Pan developed a little flat (N-1) for continuous tone
printing.<br>
<br>
The distance for all lenses must be the same. The test is only
valid for a given distance. For example I tested many of my
lenses at 2m (6.6) as that is a typical portrait distance.
A more general distance would be 5m (16.4). For general
photography you need a much larger test subject than a sheet of
newspaper.<br>
<br>
Is this a real world test? Not for most of my use but it gives
some useful information about a lens. From there you take the
lens into the real world and use it to gain a practical knowledge
of its strengths and weaknesses.<br>
<br>
---<br>
<br>
Its customary to ridicule lens testing but it gives useful
information. As long as testing isnt the whole object its
not a bad thing. Its also customary to downplay the
importance of the sharpness of a lens. Sharpness is the easiest
feature of a lens to check off so why not do that first. Its
far from the only important issue and sharpness in the real world
can easily be more about the skill of the photographer than the
quality of the lens. Sometimes sharpness isnt even desired
but if a lens has it, its easy to loose. With a DSLR youve
got a mild soft focus filter with you at all times if you shoot
RAW.<br>

<em>As I've swapped lenses over the years I'm really
wondering if different batches or individual lenses are better
than others. --Michael Axel<br>
</em><br>
Michael,<br>
<br>
I tested three 105/2.5 Nikkors, AIS, AI and IC under the
conditions noted above. The AIS was best, the AI next and the IC
last. The difference was greater between the AI and IC, than the
AIS and AI. These lenses all have the same optical formula so the
only plausible explanation is sample variation. All were good
lenses but the AIS and AI were better in terms of sharpness.<br>
<br>
<em>I own some "legendary" lenses that are no
where near as good as what others think. --Michael Axel<br>
</em><br>
Id love to say my 105/2.5 AIS is my sharpest lens but its
not so. The lowly 50/1.8 AI and the 55/2.8 AIS Micro both best the
105(s) by a clear margin.<br>
<br>
Another feature of the 105/2.5 is that its not as sharp
wide open and doesnt achieve its sweet spot until f/5.6
where other lenses I tested achieved their sweet spots about a
half stop or so earlier. This is a result of 105/2.5 being
designed to give beautiful background rendition wide open and at
portrait focus distance. This is a true feature. By sweet spot I
mean general area center sharpness. <br>
<br>
In some cases as one stops down you can see center sharpness
begin to fall off as edge sharpness is still increasing.
Diffraction doesnt just start at f/16 or f/22. Its
there all along. I find with high resolution film that if a lens
doesnt achieve its sweet spot by f/5.6 that its
not going to be very sweet when it does. Lens contrast is a
factor in image sharpness but diffraction tends to take this away.
A an enlarger easel you measure the loss of sharpness when a lens
is stopped down deeply.<br>

<em>Shun..all of the lenses...is ~10 inches from the wall...
--Edward Ng<br>
</em><br>
Edward sleep in peace: this test distance is only valid for a close-up
lens. Try a distance of 5 meters, about 15 feet, for something
more appropriate to general photography. There is a reason why
brick walls are popular as test targets ;)<br>
<br>
If you dont have a place to test with proper controls
believe you results from general photography. Forgive me but
poorly done tests are much less than useful.<br>
<br>
The reason for formal lens testing is to gain knowledge quickly.
If you have a few months or more of experience with a lens and
the test does not agree with your experience believe your
experience as the test is surely flawed.<br>

<em>What do you think the fact that there is no aperture
ring on this wonderful lense? Some said it doesn't matter but
some care... --Leon Chen<br>
</em><br>
Adding an aperture control ring to a AF-S, VR lens would be quite
a technical challenge. The aperture linkage used on AIS Nikkors
would go right through VR components. If an aperture control ring
is required then you buy the excellent 80~200/2.8D ED AF Zoom-Nikkor.
If you need AF-S and VR then you buy the 70~200/2.8G ED-IF AF-S
VR. For those with a fat wallet and classic film SLR(s) and AF
SLR(s) and DSLR there is always the option of buying both. My
wallet is not fat just now so I own the 80~200/2.8D ED AF, if it
was Id own both.<br>
<br>
Im not a fan of the G-type lens, not at all, but this lens
is special and I own three AF cameras that support AF-S and VR so
Id like one. Two other G type AF-S VR lenses that Id
love to own are the 200~400/4.0G ED-IF AF-S VR and the 105/2.8G
ED-IF AF-S VR Micro. The latter would be used mostly for candid
portraits on film but would also be useful for low magnification
close-up and PJ & PR type photography.<br>

DSLR are different from film cameras. The cost of repair can be
very high. If you plan to keep the camera several years then Id
buy a warranty extension.<br>

Who to buy from? I do not trust Best Buy and would not buy one of
their extensions. The only place Id buy a DSLR warranty
extension is from B&H Photo in NY. That doesnt mean
there are not other reliable venders but there are many
unreliable ones to avoid. I guess Ritz would be OK.<br>
<br>
For things like computer hard disks I buy from Costco as they
will replace one for several months unlike businesses like
CompUSA which will only replace a dead one for 14 days. I made
use of an extended warranty on an EPSON 1280 printer and long ago
bought an extension for CB walky-talky which never needed service.<br>
<br>
I imagine the sales people get a good commission for selling
warranty extensions so they are eager. The extensions are a form
of insurance and Im sure the profit margin is good. I
normally avoid them, never bought one for a film camera or a
lens, a DSLR is different so I bought, inkjet printers are a
fairly new technology and my two samples clogged on successive
calendar days so two were replaced. The third and final unit I
gave to charity unopened.<br>
<br>
My two cents is yes for DSLR(s) and no for most everything else.<br>

PS: for fire, theft even dropping a camera a home owners
personal articles floater is a good idea at least on the core of a
system but won't cover repairs not due to an accident.

<em>I let the flash fully charge, and I turned off the
pre-flash, but does anyone know if there's another setting that
would cause the excruciating delay? -- Michael Axel<br>
</em><br>
If you were using TTL flash (balanced or standard) you cannot
turn off the preflash. Its a requirement of i-TTL flash and
there are no exceptions. Im not sure what you did? <br>
<br>
My guess is auto focus it the problem. You might check out custom
setting 2: Auto Focus starting on page 88 in your manual but the
Nikon D50 is not feature rich like the D200 is in this area.<br>
<br>
With the D2H I separate AF activation from the shutter release
and give AF-S release priority. This assures that the camera will
take the shot when I press the shutter release not when its
good and ready. If the image is out of focus there is no
question, its my fault not the cameras. The can be done
with the D2X, D200, F5 and Im quite sure the F6.<br>
<br>
I dont know if you were trying any picture modes. If you
were the camera changes the AF modes automatically for you (whether
you want this or not). Also if you were using picture modes the
flash modes may change automatically. Im sure you can work
this out. I hope something here helps. If not you have the D200.<br>

There is an SB-28 on KEH.com today going for $109.00 in EX+ condition. 320g, ISO 100 guide of 35mm - 36m / 118 ft. This unit full supports the F5. There are several at just over $100.00 (USD).

<em>I was under the impression that the off-axis
positioning of the SB-15/27 helped to cut down on red-eye rather
than contribute to it. -- Eric Bogaerts<br>
</em><br>
I dont think I really said that it does contribute to red
eye but I was rambling and so I was not clear above. The side
mounting likely reduces the chance of red eye some while causing
the unpleasant shadows. The SB-15s flash tube is still
quite close to the lens so I would not count redeye out at least
on a camera like the FE2, FM2n and FM3a. On an F3 or F2 the SB-15
and SB-27 is further to the left so the chance of redeye should
be low with short to medium lenses. I"m still not as clear
as I should be; I hope this makes some sense.<br>
<br>
Since the mid seventies Ive been mounting speedlights above
the lens and as high as possible. I used to use an anatomical
left side flash bracket (Sunset and other various brands) with a
Hasselblad extension arm. This worked great with a Hassie or
Rollei TLR but not so well with a Nikon because it didnt
keep the flash above the lens for vertical shots. The Hasselblad
bracket I used extended at about a 45 degree angle to the right
to counter the flash shoe possition of the left side bracket.<br>
<br>
If I have the advantage of a 8 to 10 foot white ceiling (2.5 to 3
meters) my preferred method is to use 90 degree bounce with a 3x5
fill card on a cobra style flash. This can be done for both
horizontal and vertical shoots. Even with the flash over the lens
there are harsh shadows on the face and under the chin. With
bounce flash there are soft but deep shadows. The 3x5 fill
card fills the shadows left by bounce flash quite nicely.<br>
<br>
For a bit more effort a flip bracket is great but this is not
what William is looking for. Though I do not normally recommend
them as compared to the SB-800, the SB-600 is probably the best
match for William.<br>

The SB-15 does not offer balanced TTL flash nor does it offer
variable manual power. It also does not offer flash exposure
compensation. The SB-15 offers full manual power and 1/10 power
or motor drive mode, thats all. Its got to be about
as bad a choice as I can think of for balanced fill flash with
most any camera.<br>
<br>
Ive used the Vivitar 285 for manually balanced fill flash
with a Nikon FM2 and Rollei 80/2.8 Xenotar. The calculator dial
isnt the best and the calibration of the 285 is typically
over-rated but once you know the unit its fairly strait
forward to get results.<br>
<br>
Ive used manual balanced flash and TTL balanced flash with
a Nikon SB-24 and a Nikon F4s & F5. Given the price of used
Nikon SB-24(s) today I dont know why anyone would buy an SB-15.
I mostly use my SB-15(s) in MD mode to trigger a Norman P2000X
studio strobe. In the past Ive used the SB-15 with a 105/2.8
AIS Micro-Nikkor with the SB-15 flipped over the lens and the
bounce head pointed down slightly. Im thinking here of the
Nikon F2As and F3 as the flash will always be to one side or the
other with a camera whos hot shoe is centered over the
prism. I also use the SW-6 wide angle diffuser when using the SB-15
for close-up(s). Having mentioned the SB-15s bounce head I
must say the power is really lacking for bounce flash under most
all conditions.<br>
<br>
If all one wants is a speedlight for short distance snaps at a
low price then maybe the SB-15 is the right unit but price has to
be the deciding factor. The guide number of the SB-15 is only ISO
100, 18m / 25 ft. The SB-15 weights about 260g. If we are
pinching grams this is only 40g less than the SB-600. While Im
giving weights for various speedlights I might as well toss in
the SB-24. Its weight is 390g. As to bulk I cant see
the SB-15 as having much advantage over the SB-800 and I dont
believe there is any advantage over the SB-600. <br>
<br>
A some point one needs to ask themselves if saving a few grams is
the object or image quality is. If image quality is then the SB-15
is pretty low on the scale. There is not much one can do to
modify or improve the light over raw, on camera flash. With an SB-24,
a 3x5 card, rubber band and a white ceiling you can have bounce
flash with a fill card. This is far better than what little the
SB-15 offers.<br>
<br>
The recycle time of the SB-15 is more than double that of the SB-600
when both are loaded with alkaline batteries. It is faster with
NiMH but then so is the SB-600.<br>
<br>
The SB-600 offers a much better feature set for the Nikon F5 or F6
as it offers standard and balanced TTL flash and variable manual
power from full to 1/64th. Its a cobra style flash so the
flash is farther from the lens. The SB-15 is normally mounted to
the left side of the lens casting rather ugly shadows to the
other side of the subject. Since its low it going to give
that deer in the headlamps look even more and its more
likely to give red eye. The SB-27 mounts the same way as the SB-15
so the ugly shadows and red eye problem are much the same. <br>
<br>

William,<br>

The SB-15 and SB-27 are two flash units that will give you
exactly the kind of light and image you do not want. Im
really sure of this. Ive owned an SB-15 since about 1982 so
I have a certain affection for the little devils but compared to
todays speedlights they have many drawbacks. The worst is
the P&S light quality that you get for anything but close-up
photography as described above.<br>
<br>
In a lot of situations I prefer to avoid flash if the ambient
light is nice. If I can get the image I want with a fast prime
lens such as a 50/1.4, 1.8, (I dont own one but a 35/1.4),
28/2.0 or 20/2.8 thats the way Ill do it but
sometimes there is no choice.<br>
<br>
Well thats my two cents. If you still want the SB-15 or SB-27
v. an SB-600 or perhaps an SB-26 thats fine with me.<br>
<br>

<em>I usually don't use much of flash, most of time I
found flashes are too bulk and too bright provide stiff image. I
was looking at the line up, The SB-15 & SB-27 are the small
buddy that is not so heavy to carry around. --William Wu<br>
</em><br>
Too bright, stiff image? This is a matter of use or misuse of the
device. If you dont know too much about flash maybe you
should study the better use of flash. Flash used extensively by
the finest photographers.<br>
<br>
To bulky? Have you looked lately? The SB-800 is quite small and
more powerful than the speedlights you are considering. The flash
tube is farther from the lens when mounted in the hot shoe. Im
guessing here but when you say too bright and provide
stiff image you are probably talking about the hard look of
on camera flash. There are lots of ways of getting the flash off
the camera and there are light modifiers you might consider.<br>
<br>
The SB-15 is a nice little unit. I own two of these. Im not
planing to sell them but they are less than idea for use with a
Nikon F5 as they do not fully support the F5. The do not offer
balanced TTL flash and they dont offer variable manual
flash. They have no built in slave capacity such as an SU-4 mode.
They have no distance priority mode. When used in auto mode they
offer only two apertures per ISO setting. I cannot recommend the
SB-15 for use with the F5.<br>
<br>
So what about the SB-27? The SB-27 has a guide number of ISO 100,
30m / 98 ft. and weighs 340g with the head set to 35mm. The SB-800
has a guide number of ISO 100, 38m / 125 feet again with the head
set to 35mm. This means the maximum range of the SB-800 is 125%
that of the SB-27. The recycle time of the SB-27 is about 0.5
seconds faster on four AA NiMH cells but its 1.1 seconds
slower when the SB-800 is power by 5 AA NiMH cells. The SB-800
has more reserve power for a second or third flash in quick
succession so practical recycling time is likely a wash. The SD-800,
the holder for the fifth cell, adds 11g to the SB-800 bringing
the weight to 361g so we have 340g v. 350 or 361g. Not a
significant difference. As far as bulk goes there is no
significant difference either though the SB-27 is slightly
smaller. Stowed in your camera bag or mounted on your camera
there is no significant difference in size and weight to be felt.
The only thing one might notice is slower recycle times when the
SB-800 is powered by five AA NiMH cells.<br>
<br>
The SB-15 is significantly smaller and lighter than the SB-16B.
In the same way I once thought I might like an SB-27 but as
technology improves the SB-800 has taken the advantage away from
the SB27.<br>
<br>
If the cost of the SB-800 it too high you might consider the SB-600.
The SB-600 weighs 40g less than the SB-27 and has the same ISO
100 x 35mm guide number. The recycle time is 0.1 seconds faster
than the SB-27.<br>
<br>
As far as bang for the buck I think the SB-800 with more power,
more features, more accessories and the more versatile Cobra
Style is the best light speedlight available for the Nikon F5.<br>
<br>
For the F3? I recommend an AS-17 adapter and any of the SB-24, 25,
26, 28, 80 and SB-800 speedlights. I think the best would be the
SB-25 or 26 for price and SB-800 best over all.<br>
<br>

nikon 100 - 300 mm zoom lens 1:5.6

<em>But for me the 5.6 aperture, causing split prism
blackout, and dim overall focussing, was the real roadblock.
-- Neil Parker<br>
</em><br>
There are two possible solutions to this problem: the R screen
and the U screen. The R screen is like an E screen with a spit
image rangefinder designed for f/3.5 to f/5.6 lenses. I think the
A and K screens are designed for f/2.0 to f/3.5 and acceptable
for f/1.4 to f/4.0. This is my general feeling and not an official
Nikon specification. The U screen has a Fresnel lens designed to
gather light more efficiently from longer focal length lenses,
100 or 200mm and up depending on the camera. The viewfinder is
much brighter and some cameras require focus screen
compensation. The F4 requires removing the prism and a tool
such as a TV tuning tool. A special tool was supplied with the F4s/F4.
The F5 uses custom function 18. The R screen is available for the
Nikon F through F3 and can be adapted for the F4 and F5. The U
screen is available for the F through F6.<br>
<br>
F/5.6 is pretty slow for a 300mm lens, too slow for a general
purpose lens at least for me. I don't like using a lens slower
than f/4.0 with a split image rangefinder. The slowest I can live
with if I must is f/4.5.<br>
<br>
