Depth of Field vs difraction
how u choose the aperture for a close (2m) and inf focus. on a 27mm lens. if i choose aperture 11 i get a "big" Circle of confusion (0,03) but if i choose f16 i will probably get difraction. whats the better compromise? considering no shortage of light
So what conclusion did you come to? I would have said go for f16 (if necessary) and get everything within the depth of field. Whilst diffraction will reduce the sharpness of an image, it is less noticeable than something that is out of focus.
