[QUOTE="WayneF, post: 199843, member: 12496"] I am just saying that trying to compare your two images is very frustrating to me (as impossible), because the larger D800 image is obviously shown smaller (harder to see any detail), and also shown brighter, missing some of the shadow that would have helped to define the small fur strands. Compare the noticeable greater brightness of the yellow background for example. Simply not the same exposure. I don't know why not, but there it is, and I cannot see it as a valid comparison of anything, esp not resolution. I'm not sure what you did to confuse it so much. We know the cropped DX frame is obviously smaller than an uncropped FX frame. We also know the same lens standing at same place will show a wider scene view in the larger DX frame (1.5x more angular width shown in 1.5x larger frame). But using the same lens from same location, the bears head obviously ought to be projected on the sensor at [B]the exact same size though[/B] - the lens is what it is. But we do not look at the image on the sensor. We must enlarge both images to the same screen or paper print size to compare them, the DX must be enlarged 1.5x more to be same size, so it then appears enlarged, or telephoto. You are arguing in favor of this telephoto effect. Many people do like it. The DX image does appear with this telephoto effect. But this is hardly a resolution test. [/QUOTE]
