[QUOTE="WayneF, post: 199507, member: 12496"] You are kidding yourself. The crop factor does exist, and is an overwhelming major factor, regarding exactly your point. You can shut your eyes, but it does not go away. If you cannot understand why it is called "crop factor", see [URL="http://www.scantips.com/lights/cropfactor.html"]FX - DX Lens Crop Factor[/URL] Which is precisely the 1.5x crop factor. It is hardly rocket science, the details are this: D7100 - 6000x4000 pixels (24 mp) on a 23.5x15.6mm sensor (prints have to be enlarged 1.5x more). D800 - 7360x4912 pixels (36 mp) 50% more pixels, [B]which is resolution[/B]. 35.9x24 mm sensor (1.5x larger). (this 50% more pixels is NOT due to the same 50% crop factor, it is just a coincidence of design parameters). D800 will shoot DX too, 4800x3200 pixels (15 mp). If compared this limited way (to see the same view as the cropped FX), yes, then, D7100 is about 60% more pixels. But compared this way, the DX has to stand back 1.5x farther (which you did not do, you did not compare the same image view). The crop is a plus if seeking telephoto, but it is the pits if you want wide angle. It is really hard to accomplish wide angle from the DX crop factor. The lens may see wide angle, but the DX sensor crops it away. It seems quite reasonable if to compare images, that it is only meaningful to demand comparing the same actual view, which means the DX stands back 1.5x farther, and the D800 FX still has 50% more pixels (in the same view). Also the uncropped FX frame needs less enlargement to print same size. D7100 certainly has many fine features, but 24 mp being more resolution than 36 megapixels is not one of them. [/QUOTE]
