Myer,
<p>
I don't mean to be a pain, and I certainly don't mind being
corrected. However, it still sounds like you are describing center-
weighted metering rather than partial. The center five focusing
points would constitute more like 50% than 10% of the frame.
<p>
The Canon USA website Elan7/7E Specs
(http://www.usa.canon.com/camcambin/cameras/35mm/slr/elan7_specs.html)
has this to say about metering: "TTL max. aperture with a 35-zone
silicon photocell. Three metering modes available: (1) Evaluative (2)
10% partial metering linkable to the focus point by Custom Function
control (3) Center-weighted average metering."
<p>
"10% Partial metering linkable to the focus point" has got to mean
that the 10% area can be assigned to any of the focus points. It's
not that I don't believe your quoting of the manual. Perhaps it's
classic Japanese-English mistranslation? :-)
-
Jim,
<p>
The the various T-mounts should all be designed to maintain the same
focal distance from the film plane, regardless of the 35mm body the
adapter is for. This being the case, you should get identical image
size & shape on your negative. This of course assumes that the
manufacturer actually pays attention to such small details as
consistancy. The build quality of the lens may give some indication?
It sounds like a fun lens - and at that focal length, who needs AF?!
<p>
Have fun :-)

Kristin,
<p>
I concur with Jim. You say you are "taking pictures at night using
the automatic setting and flash" -- I assuming you are using the full
program mode that has an icon depicting a person and a crescent moon.
That would be the mode that Jim refers to. You would want to use the
icon of the person running, or the green box (Full Program mode, non-
shiftable). "P" will also work for you (Full Program, shiftable) but
you would have to remember to manually raise the flash (are you using
the built in flash or a shoe mounted one?). Are we correct in this? I
look forward to your response.

<p>
Yes, forgetting to turn off exposure compensation is a danger that
you must be aware of. The reason the camera is not designed so that
you must press a button every time you want compensation is the basic
assumption that you will be taking a series of photographs all
dealing with the same lighting situation. For example snow scenes,
where you may want 1.5 to 2 stops compensation every time. The other
reason it is done this way on the Elan 7 � this camera is considered
to be at the level of serious amateurs moving up to pros (& some pros
use it for a light weight backup) and all of the pro cameras are
designed with exposure compensation in this manner. The assumption is
that a professional (or someone learning to be one) will be more
aware of his/her camera settings and how to adjust them as the scene
dictates. If you are looking for a down and dirty �one shot� method
of controlling exposure value, utilize the AE Lock/F Lock button on
the back of the camera. It�s the one with the asterisk (*). It will
lock focus on whichever point you selected, and will lock the
exposure reading of the metering mode you have selected. If using
Partial, it will lock on 10% around the AF zone selected. Push & hold
the button with the target to be exposed for in the AF zone, then
recompose the scene to you desire and fully depress the shutter
button. When you release the AE Lock/F Lock button, control goes back
to the camera.

<p>
Does it say in your manual that Partial only works in the central
area? It was my understanding that the computer adjusted Partial
metering to be around any focus point. The system is well able to
read all of the 35 evaluative metering zones (& indeed does when left
in Evaluative metering mode) � when set to Partial, it just chooses
to ignore a large subset or give them reduced importance to the
exposure calculation.
<p>

<p>
I�m a little confused here. The Elan 7 has 3 metering modes:
Evaluative, 10% Partial & Center Weighted. Center Weighted is just
that. It stays in the center of the viewfinder like it always has.
Partial metering selects value from whichever one of the 7 AF points
you�ve chosen, the value coming from an circle consisting of
approximately 10% of the viewfinder area. In ECF it moves to where
you look. Otherwise it moves to where you assign it with the command
dial or the cool new AF point selector arrows within the command dial.
<p>
You can buy books concerning your Elan 7 that is more informative and
laid out to teach you all of the features of the camera and their
uses. The manual is just meant to instruct you on the cameras
features and how to activate them � it isn�t designed as a tutorial
on their use. Magic Lantern is one such publisher of tutorial books
on cameras. If they don�t have one on the Elan 7 yet, the will soon.
I�ve not used any of the guides personally, so I can�t give you my
opinion on them.
-
Thierry,
<p>
You say that your shooting habits have not changed. By this, I assume
that the weather has not become drastically colder either. Cold temps
drastically reduce battery life. You are being sure to use alkaline
batteries rather than mercury, yes? I would recommend cleaning the
battery contacts, and the ones in the battery housing with a rubber
eraser (such as on the end of a pencil). All batteries emit a slight
gas discharge when in use, and can coat the terminals and reduce
effective voltage. Make sure the camera is set to "L" for Lock when
not in use. Carry a spare set of batteries. If the problem persists,
then you must have some internal short & the camera will have to be
serviced.
-
Steve,
<p>
You may very well be correct about the link referring to the older
Canon D6000/Kodak DCS560. However there have been a great deal of
rumors flying about regarding an upcoming "pro" level 6MP EOS digital
to compete against Nikon's D1. Fuji, Pentax & a few others have also
made rumblings about 6MP cameras. I'd be really suprised if Canon did
not make an official announcement of a release date within the year.

>From the many posts I've read, I understand that primes are
>unbeatable.
<p>
This is a matter of hot contention � you�ll often see discussions on
whether the slight image quality gain on a prime lens is worth the
inconvenience of not being able to compose your shot without running
back & forth or switching prime lenses. On the high quality lens end
of things (yes, the L series) the more balanced reviews give a slight
nod to primes for image sharpness & contrast.
<p>
>followed by a couple of strategic primes and a teleconverter. Since
>this is a (budding) hobby and not a profession, I can't justify
>buying an L series zoom.
<p>
I took this as a rather strange statement, as one quality L series
zoom might run you $1500 US � but depending on the focal length & f-
stop speed of the prime lenses you are wanting to add to your
collection, you could be spending several thousand dollars! A new
50mm f/1.8 will run you $80 US, but a Macro 50mm $295, a Macro 100mm
$600, a Macro 180mm $1375, a 200mm f/2.8 $700 (f/1.8 $3900!), 300mm
f/2.8 $4650, 400mm f/2.8 IS $7500, 600mm f/4 IS $8650 � even an 85mm
f/1.8 will run you $390! So before you plan on gathering a nice
collection of primes, consider what your needs are, what they are
likely to be, and whether a nice L series zoom would actually fit
your needs & budget better.
Just what kind of photography are you interested in? The answer to
that will more truly dictate what kind of lens(es) you should acquire.
<p>
>I have my eyes upon the Canon 24-85, the Tamron 24-135, and the

<p>
I�ve owned the 24-85mm USM zoom for quite some time, and very much in
enjoy it � especially compared to its lower priced cousins. Some
reports put it down with excessive barrel distortion at the low end.
I don�t tend to spend too much time taking pictures of grids, brick
walls, or Venetian blinds � so I haven�t noticed the problem. It does
have an odd-ball lens filter size. I�ve decided to get a larger
circular polarizer filter for it (i.e. 77mm) and use a step-down ring
to fit. Then I could use the polarizer on the 70-200mm f/2.8L IS that
I will purchase (as soon as I inherit money, rob a bank, whatever).
<p>

<p>
You must weigh cost, convenience, & acceptable lens quality. You
should also try all 3 lenses on your camera, noting the balance,
focusing speed, noise, configuration, etc. Then you should by the
lens that you like best.
<p>

<p>
No. You get what you can afford. Just remember to be satisfied with
whatever you get that exists.
<p>

<p>
Sounds like you�ve already kinda made up your mind.

<p>
It just depends on what kind of photography you do.

You�ll be looking for quite some time, before you see a Canon EOS
digital down at the consumer price points!

Jim,
<p>
You were right when you thought that you'd be stirring up a hornet's
nest! :-)
<p>
Gary,
<p>
The A2/A2e (EOS 5) is still around becuase good photographers such as
yourself keep it in demand, it sits at the right price point (now in
contention with the Elan 7), and it is a good design. One must admit
however that it is getting a bit long in the tooth, and could do with
an update -- no?
<p>
The fact that it has a brighter viewfinder, higher top shutter speed,
PC flash socket, and slightly better low light AF make for a hard
choice between it and the Elan 7.
-
George,
<p>
I have the big brother to this drive (the 1 GB). You say that the G1
is reporting 0 Kb used. Have you looked at the microdrive via a PC? I
assume that your Microdrive came with a PC Card adapter just as mine
did. Are you not using a PC to manage and store your images? As long
as you don't do any actions that cause information to be written
(including creating new folders, optimizing the drive, adding files)
to the Microdrive you will be fine.
<p>
What I'm suggesting is that perhaps your G1 interface with the
Microdrive is out of sync, but the images still exist. If you find
folders &/or files on the drive, move or copy them over to the PC's
hard drive. You could then reformat the Microdrive and put it back
into the G1.
<p>
If the worst has happened, and the files on the Microdrive have been
deleted by the G1 or your PC -- all is not lost. What generally
happens is that the directory information is deleted, but the files
actually remain until written over by other files. You may be able to
recover some or all of them using a program like Norton Disk Doctor,
which can search for erased files and "unerase" them. The program may
ask for help in determining the file extension to assign the
recovered files (jpg, tiff, raw, etc.) -- don't worry if you get it
wrong, you can simply rename the file extension later.
<p>
Baring that, you'd have to do what Isaac suggests and go with a
professional data recovery outfit.
<p>
Good luck, and do let us know what transpires!
<p>
PS Isaac, I hope you had a good flight! :-)

Tim,
<p>
In response to your question about whether Canon will stop producing
35mm film bodies because of digital � I�d say it�s an
unequivocal �Absolutely not!� At least, not for many, many years to
come.
<p>
Although digital cameras in general, and digital SLR�s in particular,
are increasing in sophistication they still have a very long way to
go to even come close to replacing film. Even then, I�d see the slow
phasing out of smallest negative sizes to largest. APS will fall,
then 35mm (except for us die-hard enthusiasts), 2 ¼ x 2 ¼ �. Can you
imagine a 5 x7 or 8 x 12 CCD or CMOS sensor?
<p>
What digital has going for it is: Convenience. The ability to
directly port images to your computer (with no lag for processing,
like film) and edit it in PhotoShop, then send it off to a bureau or
print it on your personal color printer.
<p>
What it lacks is:
<p>
1. Resolution (even the 6 MP cameras coming don�t come close to fine
films)
2. Dynamic range (may match slide films, but doesn�t yet come close
to print films)
3. Capacity (high capacity digital media, like IBM�s 1 GB Microdrive
cost upwards of $500 US � for just one CF II module. If you�re
traveling in the bush, you could carry a whole lot of rolls of film,
but likely can�t afford a whole lot of CF modules).
4. Print quality (even though color printers are getting nicer all
the time, prints on photographic paper from slides or negatives still
rule -- especially when it comes to large size prints).
<p>
I�m sure there�s more pros & cons, but that should do for a quick run-
down.
-
Argh, choosing optics based on their looks?!? I'm mortified!
Hmmm...on the other hand, I do lust after those pretty white
ones...perhaps I should keep my mouth shut! :-)
<p>
Sam, In all seriousness - I've only heard good about this lens, and
am sure that you will be pleased.
<p>
PS The double posting - I also sent Bob Atkins an e-mail. I know he's
still involved & active - he replied to my thread about TC's a short
while back. He is the one with site authority to delete threads,
though. My my post to him bounces, I'll try to track down a different
e-mail address for him.
-
Puppy Face,
<p>
Thanks for the clarification! It sounds to me like the most important
decision making factor, Sam, is the purchase price of the two
versions before you! :-)
-
Puppy Face,
<p>
An EOS 5N such as you describe sounds like a dream camera. Then
again, the EF 70-200mm f/2.8L IS USM was a long standing dream that
has become reality. Maybe there's hope for such an ideal body yet. A
film body specifically designed to accept a digital back would rock!
It could automatically lock open the shutter, disable motor drive,
etc. Even more ideal, the film back could be a full frame CCD or CMOS
sensor (while we're dreaming & all)!
<p>
At this point -- and perhaps more likely -- I'd really love to see an
updated 3, i.e. an EOS-3N. If it were able to incorporate all of the
advancements of the 7E (faster & more precise ECF, diopter
adjustment, Focus point selector arrows within the command dial,
etc.) while maintaining it's own very unique capabilities (AF with up
to f/8 lenses, 7 cross type sensors, fastest AF of all EOS bodies) --
then I'd just skip the Ellan 7E and save up. Before I wake up, let's
add features from the EOS-1v, like EOS Link Software & more custom
functions! And why not bring back the integrated near IF emmitter
(can be disabled via custom function, of course)? And give it a super
user-friendly LCD interface like Minolta's Maxxim 7! Man, I'm just
getting warmed up! I'd better quit while I'm ahead. :-)
-
I'm glad to see real units becoming available so quickly. Hopefully,
the retail shelves will get some soon!
<p>
BTW -- Isn't it rather an abuse of eBay purpose/policy, to have an
bid item that you can't really bid for, and is only there for a
commercial annoucement? Kinda takes the fun out of an auction site,
I'd think.
-
Sam,
<p>
As far as I've heard, the two lenses are identical optically. The Mk
II is only a slight change -- primarily the new finish you noted, I
believe a wider focusing ring, and all Mk II's have a 7 bladed
aperture diaphram (whereas the older Mk I's have a 5 bladed design &
newer Mk I's have the 7).
<p>
I would not worry too much about which factory your lens comes out
of, when it comes from a major lens maker such as Canon. These
companies are very interested in keeping up their reputation for
quality, and all companies (whether they are based in Japan, USA, or
elsewhere) are relocating to China/Taiwan/Vietnam/etc. to reduce
labor costs. I'm sure that if they had ISO 9002 (et al) ratings
before the move that they will make sure to maintain the same quality
assurance ratings. As far as the glass goes, I think it is still
being manufactured in Japan -- it's just final lens assembly &
perhaps some parts that are being done in Taiwan.
<p>
The 28-105 USM is well regarded at its price point. I'm sure that
you'd be happy with either one. I'm not sure how you'd figure out if
the Mk I you are looking at has 5 or 7 blades, short of taking it out
of the box -- if it's even important to you (the 7 bladed diaphram
should be better for portraits).
-
Sam, it looks like you posted twice by mistake. Is it possible to
delete a post? Maybe that question should be posed to Bob Atkins, our
knowledgeable & friendly site moderator.
-
Yes, that is quite a blast of questions! I have some of my own. What
are you looking to do with this new lens that you can't do with your
zoom? 28mm is considered by most users to be wide angle! :-) [The
range of the zoom below 50mm are all "wide angle" focal lengths.] Are
you needing wider focal length? Faster apertures? Higher optical
and/or build quality? Are you looking for a better zoom, or a fixed
focal length lens?
<p>
You obviously have web access (or is it e-mail only?) For
specifications, start with the Canon lens section of the Canon
website. Then try third party makers if you can't find what you are
looking for. Sigma, Tamron & Tokina all have their own websites to
provide information on their products.
<p>
For pricing & purchase availablity, the online mail-orer houses such
as B&H Photo (www.bhphoto.com) or CameraWorld (www.cameraworld.com)
would give you both. The prices will have to be converted to your
country's currency, as they are in US dollars.
-
Myer,
<p>
It is indeed likely something very simple. It is very possible to
have your own digits get in the way of pop-up flash. I'd suggest that
when you hold the camera vertically, you are cupping the zoom in you
left had with your thumb sticking up (and partially obscuring the
flash tube). Hold the camera in your hand, in vertical framing, with
the flash up and I believe you will see what I mean. I'm always
getting on my sister-in-law about this -- she's even worse because
she rests the lens on her left thumb, with her four fingers sticking
straight up and completely obscuring the flash! :-o
<p>
The slight darkening you are seeing on the bottom/right edge of the
film is also very likely your lens partially obscuring the flash
pattern. I have the same problem when using my 24-85mm USM past about
40mm with the built-in flash. Check your lens when zooming -- some
(like my 24-85) will stick way forward at certain focal lengths. That
action, along with increased lens barrel diameter, add up to lens
shadowing with the pop-up flash. With some experimentation, you will
learn at which focal lengths each lens you own might be a problem for
you. Lens hoods will definitely make matters worse!
<p>
No, the built in flash is not completely useless. It's amazingly
convenient when compared to bulky shoe mounted flashes -- but
convenience was definitely the primary design consideration. The
engineers couldn't design a bulky, telescoping flash unit that would
detract from the sleek styling of modern cameras, it couldn�t be too
powerfully without sucking the camera batteries dry, etc. The flash
is designed primarily for use with small prime lenses or a compact
zoom like the EF 28-90. It has a narrow lens barrel, and doesn�t
stick out very far. The flash does not cover lenses wider than 28mm
(so I have light fall-off at the edges when using my 24-85mm at it�s
widest settings). Some reports say the flashes can�t really cover the
full 28mm specified either.
<p>
When used properly, the flash can be very effective � especially for
daytime fill flash. It absolutely is not meant to take the place of
shoe mounted flashes (like the 420EX or 550EX). Not only are they far
more powerful, and use their own batteries, but their tall position
makes it nearly impossible for finger or lens shadowing to occur (OK,
OK, if you have a 500 f/2.8L your going to want to take the flash off
camera)! The EX flashes also give you near infra-red focus assist (a
big plus, even if you plan to use existing light only when you take
your shot), and the 550EX can cover out to 17mm with it�s built in
retractable diffuser. Their disadvantage is added cost, and bulk �
which leads many people not to have them when they suddenly find the
need for a flash (hence the pop-up flash was born).
<p>
I hope that I have solved your mystery! :-)
-
I have heard that there is a significant flare problem with the lens
when pointed toward bright lights. With light behind you, the lens
is incredibly sharp. The flare correction may take quite a while
yet, which is why Canon has not put out more information about this
lens.
<p>

Warren, Thank you for your e-mail. I also clipped & pasted it to the
400mm f/4 DO IS thread, so that it could be shared with everybody.
What you said makes perfect sense to me, with all of those added
planes & angles to factor in. I would love to see test photos taken

In response to the Leica lovers postings...
<p>
The Leica R6.2 is going for $1895 to $1995 in the USA, which equates
to 89,160R to 93,865R -- body only. The Leica R3 body only, used,
goes for about $695 US, which equates to $32,700R. A used 50mm
Summilux f/1.4 is over $400 US, which is over 18,000R
<p>
If you look at 5th sentence of the post, Vivek has only 25,000R to
spend -- for body, lenses, filters, flash, etc. $350 CAD still comes
out to 10,720R for body only -- leaving Vivek 14,280R with which to
buy Leica lenses, compatible flash, et al (and that's if by some
miracle he finds a fully functional R3 at that price in his country).
<p>
The Leica/Leitz/German optics are truly renowned for good reason, and
the R3 & R6 bodies manufactured by Minolta (to Leica specifications)
are very nice. But it all comes at a price that does not truly fit
the constraints of the poster's situation. Please do not let your
devotion to a truly fine camera optics maker blind you to the
requirements of others seeking advice. Or am I mistaken, and you were
actually offering up your kits to Vivek for 25,000 Rupee (including
shipping)? :-)
<p>
Vivek, the advice of the other posters are quite sound. A new or high
quality used 35mm body from one of the major brands should do very
well for a first camera. Sticking with the same manufacturer label is
usually nice � but not always within budget constraints. Most
importantly, take your time, educate yourself with the help of
friendly and non-pushy salesmen, fellow students, and/or instructors.
Don�t bring money with you on the first visit. Handle the cameras you
are considering & even perhaps run some film through them. Get used
to the various control layouts, and pick the one that most appeals to
you. Something else to consider is how easily & inexpensively a
camera can be repaired in your country. Very rare or very expensive
cameras may cause you grief in the future.
-
Ah, the F1...I remember positively drooling over that camera when it
was released! The ruggedness, interchangeable viewfinders & screens,
the handling. I use to stop by the local pro shop twice a month just
to hold one in my hands. I should look into finding one, as a solid
cornerstone to my collection! Isaac, you are right. That thing was
absolutely cutting edge when it came out, and Canon really played it
up. I still remember the ads with engineering grids and lists and
lists of specs. That camera is probably solely responsible for making
me the photographic technophile I am today! It does my heart good to
know that these tanks are still out there, capturing images even
after all of these years! ;-)
<p>
As much as I love modern photographic technology, with its
electronically controlled shutters, aperatures, exposures, etc. --
I've got to say that there's something magic about a well engineered
mechanical marvel that can still function without a battery. We gave
all of that up for our EOS bodies, there being no point in having
manual film advance and shutter trip when aperature control &
shutterspeed control depend on electrical current. Thankfully, modern
35mm cameras seem amazingly reliable, and carrying a spare set of
batteries isn't too difficult.
<p>
* Isaac, my appologies for getting off subject -- and thank you for
posting a question that has led to passionate & interesting exchanges
of viewpoints!
-
Your brother is going from a manual focus AE1 to an AutoFocus Elan 7.
Why is your concern AF in low light? Is it due to lack of split
focusing screen on most AF bodies? How much low light photography
does your brother do?
<p>
I only ask this to place the capabilities of the Elan 7 into
perspective. If low light AF is a priority, and a fast lens + AF
assist on the 420EX is not sufficient, then you must simply settle on
a different body. Keep in mind that 1 EV change is a one stop
difference. Get a cheap & fast prime lens (like a 50mm f/1.8) for use
in such situations & it'll more than make up the difference of 1 EV +
the 28-135 f/3.5-5.6 IS (as far as autofocusing is concerned. You
might get lower shutterspeeds while hand-holding with the IS).
<p>
It comes down to whether the positive features of the Elan 7 are
worth the disadvantages, bearing in mind that there no perfect
solutions.
-
Speaking of masking, does anyone know if the 35mm EOS cameras
actually mask off the 35mm negative, or if they just have guide
markers in the viewfinder? If they do mask, is there a selector
switch to move back & forth between panoramic & full frame modes --
or do you have to shoot the entire roll in one mode, open the back
and add/remove the mask?

My apologies, Kristin, the program mode icon I was thinking of
depicts a person with a star over their shoulder, not a crescent moon
(I should have looked at a camera instead of relying on faulty
memory)! In any case, is that the program mode you were using for
your night/dark scenes?
