Ok, I keep hearing about how smaller apertures give greater depth of
field and apparant sharpness to a point, and then the increase is
nullified by a rise in diffraction.
My question is this: at what point does this happen? I'm not looking for
the mathematical equation to figure it out, I just want to know for a
given 35mm lens of a given length, say 25, 50, 100, 200, or 300, what
would be the best aperture for sharpness.
Thanks, Steve Goss, Dallas Tx usa
