So far I love the camera--very fast. My 70-200 EF f/2.8 IS II with the 2X TC focuses much faster and more accurately than with the 7D. I'm amazed in the noise improvement. Will take me a while to get used to the placement of the AF change buttons--I was so used to the 7D after using it for 5 yrs. Here's a couple of ISO 12800--yes, 12,800!! taken with the 70-200 + 2X on manual and dev with NO changes in DPP except adding the lens correction. It think they are pretty incredible for the ISO. They would have been so ugly before.
Are these 100% crops or are they the whole image resized down 3-4 times.
