Hi Guys,
I shoot a lot of film, but I have a Canon DRebel with kit lens that I'm thinking of getting new lens for. The
kit lens is too slow, so I want to get a faster lens at a reasonable price. I have the 50mm f1.8. I'm looking
at the Tamron 17-50mm f2.8 and the sigma 28-70 DG f2.8. I have an EOS film camera that I don't use
much but if I did get the sigma I believe I could use it.
Functionally, I have the 18-55mm range covered with the kit lens. If I'm shooting really wide I could still
use the kit. I'm concerned with image quality wide open primarily.
Anyone use these lenses? Any thoughts?

Although this camera isn't exactly super light weight, the concept is that a 4/3 camera
could be smaller and lighter than the equivalent 3:2 camera. With a 2x crop factor on a
fast lens like their 90-250mm f2.8 you could have a really fast 500mm f2.8 equivalent
lens.
I like the idea of the light weight, not so sure about the increased DOF and the effect it will
have on portraits. For some it may be a bonus. I recall somebody shooting photos in Iraq
with all point and shoots who was using the small sensors to get incredible DOF images.
I think the system is interesting, another option to consider. As with everything, its about
the right tool for the job.

Interesting note - no info about the product on the Japanese homepage. An unusual move
for a Japanese company.

amazing folder - check out the whole set.

D300 vs D2x
in Nikon
I was reading a Japanese photo mag in which one of the Nikon marketing guys was answering
Q&A. If I read it correctly he observed that the D300 is the best DX format camera that Nikon
has produced. D3 is the best FX format, D300 is the best DX format. food for thought.

Sorry David,
not sure why it doesn't work for you from the link above.

Some flat bed scanners come with slide and film holders. You can get decent scans this way.
Otherwise your best bet is a dedicated film scanner; as far as scanner options go anyway.

The list price in Japan is 33,000 yen with shipment expected around now.

open up the lens means setting it for the widest aperture. The widest aperture is
represented by the lowest f number. f2.8 is your widest aperture. R Jackson explained the
issue you may be having, as caused by depth of field. When you shoot wide open, you can
use a faster shutter speed because you are allowing the most light in at once. But, you
depth of field (imagine a football field) is the shallowest this way. For instance you may be
shooting from the end of a field with a wide aperture, f2.8, and everything from the 20
yard line to the 30 yard line is in focus. But, if you use f16, maybe the whole field is in
focus.
When you start focusing closer to you, 5-6 feet away, this effect is compressed so that
people standing in rows may be in and out of focus depending on your depth of field.
look into aperture and depth of field in any of those field guides you see for cameras at
your local book store.

Don't bother with a G3 ibook; if you don't want to deal with a second screen get a G4 ibook
or above. If you have a second screen kicking around then get a mac mini used or new. this
is the cheap solution anyway.

Alessia,
There is a brochure available for Bogen Elinchrom light modifiers shot by Joe McNally. It is
a neat brochure of how you can use different lighting setups to achieve different effects. It
may help just give you some quick ideas for lighting and model positions.
email Bogen and ask for it; it is a beatiful large print brochure.

scanning then printing works well. Get a good scanner though; ideally a 35mm film scanner
if that is all you shoot.

despite the obvious chellenges, I have done quite well with a large coffee can as my mixer/
container and portioning out Microdol-X. Is it perfect? I don't know. But it does what I want
it to. More on that buried somewhere on my website.

Thank you Garry. For sake of clarification:
who are the moderators for the News section? Currently listed are
News - Bob Atkins, Patrick Hudepohl
-
perhaps I misunderstood - is it not to be deleted?
-
If it is incorrect, then the information listed under the "about us" link at the bottom of every
page is incorrect. I guess, as a general concept - how should I rephrase this post to make it
acceptable in a more general form?
I am of course concerned that my post is to be deleted.

The member who submitted the news (Bob Atkins) is one of the two moderators for the
News section - which presents an interesting issue in this case. He is also an official
contributing editor (1 of 3), as well as the official technical editor for PN.
I don't have a problem with Mr. Atkins, and I certainly don't want to create an unintentional
animosity. I find his writing amusing at times and his knowledge to be very helpful. But, I
have strong opinions about the reporting of news - and this is an important issue to me.
It is somewhat inevitable that reviews will have opinion - I tend to read the conclusions of
reviews first. But, news is a different animal and so that is why I post my concern.
-
as a subscriber for the past year, I am concerned that this site seems to have a bit of a Canon system bias.
I don't speak of the clientele, but rather of the reviews and now the news.
"Nikon catches up--finally adds VR to their telephoto lenses"
This isn't a news headline - it's tabloid journalism.
It would be like saying "Ford catches up - finally adds power steering to car." It makes assumptions that
may or may not be true. It assumes VR is a necessity and not a feature; and that by not having it the
lenses have been somehow deficient.
Now, this may or may not be true - it is a matter of opinion. But, that isn't the point. The headline should
read "Nikon adds VR to new telephoto lenses."
Don't shrug it off - consider the impression you are giving your readers. You should be reporting the
news, not interpreting it. That's what the rest of the forum is for. Join in the discussion if you want; but,
let the news stand on its own.
note: I use a Canon DSRL for most of my work, and Nikon & Hasselblad for fun. So, I don't want to be
accused of being a Nikon proponent either. My choice of primary camera could change tomorrow (and
may); whatever does the job well is the right camera.

This is a list of cameras used by ISS and shuttle according to:<br><p>

this information on the ISS: from <a href="http://earth.jsc.nasa.gov/newsletter/Health/
shuttle.pdf">http://earth.jsc.nasa.gov/newsletter/Health/shuttle.pdf</a><p>
The International Space Station (ISS) has an average altitude of 407 km (220 nautical
miles) with an orbital inclination of 51.6?. The U.S. Laboratory Module on the ISS will
have a window, with a clear aperture 50.8 cm in diameter, which will be perpendicular to
the Earth?s surface most of the time. The window?s three panes of fused silica give it
?optical quality.? Instrumentation for Earth observation will include, but not be limited
to, Hasselblad, Linhof, and Nikon hand-held cameras, plus sensors and imaging systems
still to be developed.

upgrading from kit - tamron/sigma 17-50/28-70? opinions needed
in Canon EOS Mount
Posted
Hey Guys,
Just a follow-up. Picked up the Tamron. Debated a slightly less expensive Promaster
(supposely the same lens as the Tamron w/ a lifetime warranty), but opted for the
namebrand (offbrand?).
Used it the same day for a shoot. It allowed me to do what I wanted to be able to do.
Good amount of light in a dark room, sharp photos. I ended up needing the added wide
angle over the 28-70. Shot some with strobes at f4.5 but looking at the results, I think
this still beats the kit and was worth it. The constant aperture over the entire zoom range
was the key. Using manual flash ratios, didn't need to worry about the F changing over
the zoom range.
