[QUOTE="§am, post: 120646, member: 9187"] I too am not here to argue, but I am here to learn :) An 85mm lens on DX is equivalent to 127.5mm on FX (or 35mm) due to the crop factor, and don't these calculators take that into consideration when calculating these results? From my understanding, to get the same picture (frame) on FX you have to move closer than DX (due to the 1.5x crop), so that you can get the exact same pic. At which point your DoF then changes, and its this that is taken into consideration when calculating the values from the various online calculators? I'm sorry if I've confused you or even myself now, just trying to learn more about photography in general. [/QUOTE]
