Best 24-70 f/2.8mm for handholding on D800?

Isn't it true that with the D800 at the pixel level the FX and DX modes have the same basic resolution. They are the same pixels. DX has 1.5x less FOV for an apparent increase in the telephoto effect. The only advantage I see for the DX mode with a DX lens is that it crops the image in the camera instead of you doing it in PP. Of course, the other potential advantage is smaller file size.

Another point to be made is that the basic resolution of the D800 and D7000 is the same. The pixel pitch is close to the same for both cameras. Only the amount of pixels in the picture is greater for the D800 because the sensor is larger. Therefore, for a given size print from both with the same FOV the D800 has more pixels in the print and can look sharper. The greater number of pixels in the D800 image gives it more leeway when cropping to achieve a different composition.
