The flat plane of focus is an idealized situation, few lenses actually
have a rally flat focus plain. Most exhibit some curvature.

fail. I move the focus point and carefully focus on subject's eye.
Many thanks to both you and Matthew! I really hadn't understood about
the flat-plane focus, and I appreciate the mini-lesson. I should do
some experiments to get more of an intuitive understanding of what's
going on.
For the above, do you only do that with a tripod, or do you also do it
with handheld shooting?
