[QUOTE="J-see, post: 424605, member: 31330"] Look here's the Wiki on DoF: [URL="http://en.wikipedia.org/wiki/Depth_of_field#Close-up_2"]Depth of field - Wikipedia, the free encyclopedia[/URL] The DoF in macro is a fixed formula with an outcome depending upon magnification and aperture alone. Changing one of both, or both affects the DoF which implies that you can get the same DoF by using a low magnification wider open or a higher magnification closed down. That's why the DoF of f/8 and f/32 at their different magnifications is identical. You can use other settings too and get similar results. So in the end this is not about DoF differences since there are none but about quality loss. How much quality do I lose when shooting close down fully embracing diffraction versus how much quality do I lose by shooting a bit further and cropping. I'd say at worst you lose the same quality cropping than shooting closed down. Here's about diffraction too: [URL="http://en.wikipedia.org/wiki/Depth_of_field#Diffraction_and_DOF"]Depth of field - Wikipedia, the free encyclopedia[/URL] [/QUOTE]
