This is also my question - comparison between the new Mark 5 III and DX? I am a wildlife photographer who specializes in Africa but during the "off season" I shoot mostly mountain landscapes. I have several questions - 1. What are we getting by spending $2000 more dollars to buy the DX? Yes, 12 frames per second, but most of the time the 6 frames per second that the new 5D III offers will be good enough. Weather proofing - a bit overrated in importance in my opinion. Better metering? And obviously the big question 22.3 MP vs. 18 PM and all important IQ - this is what really matters. I have the money to buy either camera but not both. I have a 5D Mark II (which I really like and it focuses fine if you only use the central square) and a Mark IV which I also like. I sold my extra Mark IV to buy new technology. I want outstanding focusing speed and high IQ but I am leery of the $6500 price bump for the DX UNLESS it is significantly better than the new 5D Mark III. I don't really get Canon's marketing strategy and OMG I want to see images from both cameras in real life tests side by side. Oh, VIDEO - I could care less about this - I shoot stills and this is what I love to do. Oh and finally if I have to shoot above 3200 ISO it is raining and I am back at the lodge drinking Tuskers.
