My K-5 required minor adjustment. It's important if you use autofocus wide

I had three suspect
Does any one on the list use this setting on their bodies, to adjust the AF
setting on the lens.
I was having trouble with AF on the K7 with the Pentax 16-50 2.8. lens..I

It's a somewhat lengthy process Mary, especially if you have a few
lenses to do, but it's *well* worth the effort. I have done it with
all my oft-used glass on my K20D and I will do it all over again
if/when I upgrade. You need a solid floor and a well-settled tripod to
do it accurately.

I dial in the autofocus on all my lenses. It's fairly simple and well worth the
effort. You can find instructions and targets for doing it online.
With that 16-50/2.8 you should also check to make sure the focus field is flat.
You can do that by shooting a brick wall off a tripod at f 2.8.

Step #1: choose AF point = SEL. Don't use Auto. That's what I find so
frustrating with Point'n'Shits, they *always* focus on the wrong

That's pretty much what I do. It's not entirely accurate to say that I never
