Default To markogts: diffraction problems

Hello Mark !
I set F/29 for better DOF. The difraction is depending on the kind of the light. Could you explain more ? (what's the problem ?)
Regards, Agnes

Well, theoretically, the maximum resolving power of a lens is strictly connected with it's aperture. If the aperture is too small (beyond f/16) the blur caused by the small diameter of the lens is bigger than the pixel size, so you get a loss of sharpness. Here you can find a better explanation.
