I have a project which requires an SLR with a very long focal length
lens mounted in a difficult to reach location.  I would like help
choosing a camera and lens that would allow me to take photos from a
little distance away, connected with a data cable.  Here are my

Does anyone know of the fastest shutter speed (on a Canon 20D) that the
580Ex flash will sync with?
Thanks

Note the use of UD and aspherics, as all good DIGITAL lenses have.

Too bad it won't work on a 5D though.

I purchased a 17-40mm f/4 L lens - It arrived yesterday - I mounted it
on my new Canon 20D. The results are very disappointing...
I have put some of the focussing tests on a web site:

With more pixels being squeezed into Nikon's DX format (10.2 with the
D200), and the pressure from Canon with their attractive (and somewhat
affordable) full-frame censor cameras (e.g. Canon 5D), I'm beginning to
feel concern that my investment in DX lenses will go to waste in a ...

... about the D200.
I think that, on reflection, the 17-55mm kit will suit me for everyday
purposes, and the 85mm f1.4 will be great if I ever have to shoot bands in
low light or very tight headshots. Recent personal revelations about the

I was thinking of buying one of these from a store but don't know the
differences, if any, between a Digital Rebel 300D and a Digital Rebel KISS.
Can someone clarify?

I know that this has been debated ad naseum but once again into the fray.
Since purchasing my 20D I have taken all my shots in RAW.  The files are all
about 7 - 8 mg and I back up to two hard drives and one external hard drive
(Maxtor and love it). The camera is used primarily in ...

Has any one tried out any of the Pentax Digital SLRs and how do the old
style lenses from say a Pentax SF1 work on the new Digital Models
Thanks Don

Hi, I have a Nikon D-50 with a Sigma 70-300mm 1:4-5:6 lens.  I am
trying to photograph my daughter at ice skating events.  I have used
monopod and also a tripod, with flash off for athlete consideration.
The pictures are never clear. Very blurry.

It seems as if everyone is trying to squeeze the last pixel out of the
sensors, but then the cameras are almost universally sold with zoom
lenses.
My experience has always been that prime lenses provide better detail

I am going to buy an entry level dslr in the next month.
We spend a lot of time in the gym watching high school volleyball and
basketball, and you can imagine the results with a regular compact
digital camera.

OK so I tested JPS's claim that overexposing a sunset won't lose
saturation if you darken in post-processing. It worked. In daylight
conditions there is a risk of irretrievably losing blue in the sky
before the blown highlight warning flashes but in a low contrast sunset
