ok so here are some 5d mk II samples from this weekend. they're all either shot ISO 3200 or 6400, but mostly 6400.
all shot full raw and converted and resized with lightroom. some have noise reduction applied through lightroom, mainly the darker ones. the bright pictures with even lighting were left as is.
1. my favorite of the night
sigma 30mm f/1.4 cropped
30mm @ ISO 3200 f/4 1/50s with flash bracket and 580ex set to 2nd curtain sync & lightsphere attached
2. i really need to get the battery grip. i'm terrible without it.
70-200mm f/2.8 IS @ 85mm ISO 6400 f/2.8 1/60s
3. 70-200mm f/2.8 IS @ 70mm ISO 6400 f/2.8 1/30s
4. 85mm f/1.8 @ ISO 6400 f/1.8 1/125s
5. 30mm f/1.4 cropped to an 8x10 you can see the vignette from the aps-c lens
30mm @ ISO 6400 f/2 1/40s helped with someone else's flash
6. 30mm with no crop at all so you see the full effect of the aps-c lens on the full frame
30mm @ ISO 6400 f/2 1/40s
7. 85mm ISO 6400 f/2 1/100s
8. i'll round it off at 8
85mm @ ISO 6400 f/2 1/100s
as far as the 5d II is concerned, IMO it has to be the best wedding camera out there. the ISO 6400 capabilities are AMAZING! i didn't even try the 12,800 or 25,600. the autofocus is fine, definitely slower than my 40d, but not as bad as i'd expected from what people said. i'd say it's comparable to my 30d's autofocus..and i never had a problem with that. once it locks it's dead on. it fits great in my hand. the lcd is far better than anything i ever expected to see in a camera. on my 30d and 40d zoomed in all pictures look soft, on the 5d II you can definitely tell if they're sharp or not. other than that, everything else is just bonus.
