5D3 vs D800: fun vs sensor quality
May be 5D3 is fun to use, but D800's sensor is superior to that of 5D2. Actually Canon did not improve the old 5D2's sensor, and in the review there is no indication that the 5D3's AF or metering is superior to D800's. Add extra money and be happy:). That is not to say that 5D3 is a poor camera, I just do not understand why upgrade to it from 5D2 for $2000 (used D2 vs new D3) or buy it for the first time over D800. That would be a rather specific decision, so I doubt that the sales of D3 will be high.
