Thanks to Gary R. and John Hudson for pointing me to the URLs for 50mm lens
comparisons. Funny thing is that I have looked at Gary's tests dozens of
times but never taken the time to browse the 50mm lenses. Oops!
Okay, so here is my new question:
I'm getting into macro work and have noticed a somewhat annoying phenomena.
If I maximize depth of field (or at least preview to get the subject in
focus), the subject is in focus but definitely muddled. With a shallow DOF,
the subject is out of focus, usually, but the parts that are in focus jump
out at me.
I have three thoughts on the source of this:
1) a loss in contrast of a particular lens at smaller apertures
2) some sort of optical trade-off of a larger DOF in all lenses
3) or just my own eyes distracted by other items in the frame becoming more
in focus
Any thoughts on the cause and solution to get the subject in focus and
preserve 3D effect? I am trying to solve the problem by using lenses at
their optimum aperture and also trying to set the depth of field for just the
subject. Two tasks which are not exactly complementary in macro work.
Anybody else have/had this problem? What are/were your remedies?
