I used manual focus exclusively until about five years ago. But I'm
over sixty and my eyes aren't good enough to focus accurately when
quickness is an issue. More importantly, autofocus has progressed to
the point where it's very good, and even someone with good eyes can
benefit from electronics that allow one to be instantly reactive.
I can walk, but a still drive a car much of the time.

If you look at my photos on my page on Photo.net all my photos are
shot with manual focus except the photos that say test under them,
that were shot with the 70 - 200 mm Simga lens. Now I understand
when someone's eyes are not as good as they used to be, you will
tend to use auto focus, but they do make contact lens and the like
to improve your eyes. We as photographers and people are getting
lazy and not using our brains.Sorry if I offended anyone on the
list. I will admit there is times when I try the auto focus, but I
go back to manual focus all the time...Joe

My K20D front focused with the FA 50/1.4. I had to adjust the the
camera using the menu option for focus fine tuning.

When I was shooting with my pfa-50/1.4 tonight, there were several

A lot of the shots with that lens seem to be way out of focus. Are
any
lenses particularly prone to tricking the camera into thinking that
they are in focus, when they actually aren't?
I don't seem to have this problem on other lenses.
It doesn't seem to be a motion blur issue.
I was shooting tonight, in raw, in several modes of high iso noise
reduction at ISO 3200. At first glance it doesn't seem to make any
difference, though I'll still have to test more scientifically.
I got a call from Mark Davis at Pentax today to discuss my
issues. Without looking at my pictures he seemed to think that my
camera sounded like it was performing nominally. After the
conversation, I emailed him the links, with explanations, to my
various test sets, but I haven't heard back.
A lot of frustrating things may be happening with my camera, many of
them quite likely my doing, but I must commend Pentax, and especially
John C, because they seem to be making every reasonable, and perhaps
even some more than reasonable, effort to resolve the issue.
On the bright side, I seem to be learning a lot about my camera.
