Hi
Went to the bird park to check out the 50D.
All af is AF AI Servo Single center Point
ISO 400, 300 F4 using 1/1000, F7.1, size Reduced, unsharpened, Manual Handheld, IS set to PAN
Highlight recovered on head via PS .. This is on shot in focus out of 10 shots. .AF gets easily
confused.
** seems dynamic range improved, I can recover all of the 'blown head' **
Photos on Tripod, no shutter release with and without TC all using 400 F5.6
Bird under shade, Side light
ISO3200 - Denoised and sharpened - Very little noise when there is enough light.
400 F5.6, 1/250 F7.1 No TC - However shorter exposures will bring up ugly Luma and
red noise!
ISO 800 Crop and 1.4tc.. the 1.4tc adds a little softness. ISO 800 Photos at F7.1 and F8
Photo with TC was downsized by eye to match the Eye size of the bird without TC.
Rescued Vulture in flight, sharpened, a bit of Velvia, ISO 400 300 F4
Without any TC, the 300 F4 had a hard time locking on to the birds at the
Raptor Arena area because there are so many leaves, people etc.. I think
bird against the sky its very good. Its a hard place to focus. However under
the same situation the D300 AF works!
However in contrast my D300 can track on coming birds the 50D, so far
it has failed to do that under the same conditions.
* I found an annoying issue with the 50D. IN Manual Mode Auto ISO is FORCED
into ISO 400 unless you set it manually. So basically there is NO 'auto iso'
in manual mode.
I think this is a very limiting factor given that we have improved noise qualiies
and is not able to take advantage of it on the fly. I would have liked to
set a Shutter of 1/1000 and F5.6 + ISO = Auto so that I can catch flying
birds at the lowest possible ISO depending on the lighting situation..
Too bad I cannot.
Anyway hope these photos help you make the decision to buy one.
