OOC JPGs? If so, that is a big part of the improvement, the JPG and NR engine finally got a facelift a few models ago.
I don't know what you in the bolded section? Shutter speeds have nothing to do with your camera, are you saying that before you would shoot at f2.8 and faster shutter speeds, and now you can run at f4 at slower shutter speeds? Again, that wouldn't be a camera thing. The ISOs you run at would be camera-related.
I would use ISO 6400 on the 7D quite often, but 12800 required finesse with settings and post processing. I can do ISO 25600 on the 5D3 and get close to the same results now with almost the same kinds of post processing steps. Nice!
Totally OT, TeamSpeed, but how has Tony Mitchell looked this year when he's played for the Mad Ants? I was psyched when the Pistons drafted him, even if he is a bit of a project.
