[QUOTE="Marcel, post: 120651, member: 3903"] You know what, everybody is right. But we don't have the same words to express what we know. There are many factors in play here. Let's start by defining some of the words we use. When we compare FX and DX, it is true that to obtain the same picture (Field of View or FOV) from the same distance of the subject, we have to use a different focal length of lens. So, in reality, when you want to have a certain FOV with both and are using the same aperture, you would end up with a little more Depth of Field (DOF) with the cropped DX version since the lens focal length would be smaller by 1.5. But, if you use the same focal length on DX and FX and you move away from your subject with the DX to get the same FOV you would still get a little more DOF because you are further from the subject to start with and distance and aperture do affect DOF. Now the rest is a question of taste. Some photographers do prefer to have everything in focus and others want to have the background out of focus to feature the subject a little more. This is where you can benefit from a narrower DOF. As far as the difference in quality from DX and FX, I'm a strong believer that FX makes better larger prints specially at higher ISO. I have both formats and can attest to that. [/QUOTE]
