I see a lot of the old "there are no lenses good enough for 36MP!" cries going on in this thread.
That is just not true. The final resolution of a camera system is a function of all of the pieces in that system. A higher resolution sensor will increase the overall resolving power of the system.
But don't take my word for it. Go see the tests here:
Note that the Nikon 24-70 by itself is less sharp than the Canon 24-70. However, when fitted to a D800 it out-resolves a Canon 24-70 on a 5D Mk III... the higher resolution of the sensor making up for some of the inherit deficit in the lens.
I just can't wait until a ~36MP Canon comes out and we can stop seeing all of these ridiculous "I would never use 36MP!" posts. Everyone can use more resolution, regardless of your style of shooting. Now whether you truly "need" 36MP (to the point where you would put down your money for it) is something else...
The D800 is certainly a nice camera, I wouldn't think there is any argument there.
I paid $3,000 for my D8oo last May, and its dropped in value by $800 more or less. I paid $2700 net ($50 Rebate) at Adorama for my 5D MK III last September after selling the D800, and the average used 5D MK III now sells for almost $2800 on ebay.
I was asking why users thought the D800 price had dropped so much in comparison. Even if you consider that the 5D MK III has dropped $800 from its original selling price, it isstill a lower percentage price reduction.
