[QUOTE="Kaleun96, post: 7996234, member: 92635"]That's a good point as the effective aperture of the lens is likely much higher than f/10 and probably well into diffraction territory. It's probably easier to just test different aperture settings and see what gives you the best balance of sharpness vs depth of field but if needed, Nathan, you can calculate the effective aperture using the following: [B]N' = N*(m+1)[/B] N' is the effective aperture N is the actual aperture setting m is the magnification To get an estimate of the magnification, the easiest method is usually to take a photo of the ruler and divide the actual width of your camera sensor by the photographed width as measured on the ruler. So if the ruler measured 10mm across in the photo on a sensor 35mm wide, the magnification would be ~3.5x.[/QUOTE]
