[QUOTE="WayneF, post: 205035, member: 12496"] Each of us should use what we prefer of course. My own choice for high resolution would be the opposite. But if you fill the D800 frame, you have 36 megapixels. That is resolution! As of today, nothing DX can come close, not 12 mp, not 16 mp, not 24 mp. Yes, you might compute that 24 mp DX has pixels closer together on the sensor. But so what? The small DX sensor has to be enlarged more, and the pixels are wider apart then, with smaller CoC. The DX will never be 36 mp. There is no way you can show in 16 or 24mp what can be shown in 36 mp. I think you must not be taking advantage of your 36 mp. I think you said that a 36 mm long object in 36mm wide frame is 1:1. Yes. In a 24mm wide DX frame at 1:1, it is cropped off, incomplete, so if you have this 36mm subject size, then you must back away with magnification, and use only 1:1.5 or 67% magnification. You do this by standing back 1.5x farther. Which longer focal length could be said to be greater DOF, but the smaller DX frame has to be enlarged 1.5x more, and CoC is 1.5x less, so there is no advantage. But it is overwhelming that the D800 can be 36 megapixels, and the DX can not. [/QUOTE]
