[QUOTE="BackdoorArts, post: 122747, member: 9240"] My understanding is that resolution, in terms of MP's, shouldn't change as you use the crop modes on the D800 (FX, 1.2, DX) if the resulting image is then cropped to an identical size and nothing else changes (i.e. focal length of the lens). For example, in the Cockatoo photo, the bird is within the confines of the DX box in the viewfinder, so the only thing that would change in each of the 3 shooting modes is the size of the initial RAW/JPEG file. Once cropped down and exported at the same dimensions (100% crop?), the resulting images should be identical in every way. In other words, when shooting in DX mode you get the full resolution of the middle 43% of the D800 sensor. There are fewer MP's only because the area of exposure is smaller, but the resolution within that area is identical to what you would have gotten in FX mode and then cropped to 1.5x. The sensor doesn't adjust to the mode, the camera just adjusts which portion of the sensor is used. IQ should be identical. [/QUOTE]
