I suspect a relatively small number of cameras with a real problem got
repaired and the pixel peeping madness fizzled out.
AF is not perfect. Like DOF, it just needs to be close enough, which
varies with use. I've noticed with complex subjects that putting the
central point directly centered on the point I want to be the focal
plane that I sometimes get instead something nearby, and slightly closer
or further away. Generally, moving the focal point slightly and
half-pressing again will do the trick in a try or two. With
close-up/macro, sometimes it just needs MF.
I find the ability to select AF AOV on the E-3 interesting. I wonder if
it would be much use in practical field conditions.
A perfectly accurate AF, when you located the AF point on your subjects
eye, would ask you whether you wanted the focal plane at the nearest
point of the roughly spherical object it detects, the deepest visible
point of it, or at an average. Then it would want a discussion of the
amount and desired direction of DOF.
I don't think I could deal with that for regular use.Would it sound like
a GPS navigation system?
