After a little reading and reviewing the RAW files I have canceled my pre-order here in Thailand. I was caught up in the hype. hummm
Here is some good reading about the AF systems on EOS cameras if anyone is interested.
I just wonder what the expectation everyone had with 7D2... it's quite obvious that this camera is not IQ priority... the 7D2 is all about speed... speed to capture the moment.
I sold my 6D once 7D2 is announce... 6D is an excellent camera with very good IQ, but since I use my camera mainly for birding, I had a problem with 6D: 6D don't focus well when subject is small and most birds are "small" especially for FF camera... even my old 60D focus better than 6D for birds. So basically:
1) 6D will give an excellent IQ, but high chance of out of focus image, Or
2) 7D2 had high chance of getting an in focus image, but there will be a lot more noise.
So my conclusion is to sell the 6D and get the 7D2 (since I can't afford 5D3 or 1Dx) because as noise reduction algorithm and computation power improve, the possibility of cleaning up a noisy image is higher than to make an out of focus image in focus.
Have a nice day.
