[QUOTE="Mycenius, post: 173007, member: 14714"] That's not quite true actually, is it...? If a DX camera and an FX camera are both 16MP then the DX should in theory have more detail per pixel, as it's captured a smaller image area in the same number of pixels (e.g. the DX has 1.5 pixels per blade of grass while the FX has only 1 because there are more blades of grass in the image)? I am not 'hands on' familiar with the Crop Factor option (haven't played on my D7100 but that's possibly different to FX anyway) but as I understand it it on an FX it just crops the sensor area down to the same area as a DX - so it is doing exactly what BC says, and it's not actually increasing the pixel density, but that is only half of the story of what DX does...? You get the zoom effect, but it won't be the same as if done on an actual DX camera because you don't get this increased pixel density? e.g. In my example above the FX camera will only use 10.6MP in DX Crop mode, so it's image is zoomed more than with full FX and the same lens, but the detail/pixel density is no better (i.e. even though it gains the zoom effect to reach out it's reduced the pixel count used to capture it) - so it's kinda halfway in-between (more zoom than an FX but not the full effect of a DX)... ...or have a missed something completely? :) [/QUOTE]
