shouldnt the lens distance scale go all the way to the end, infinity, if you aim the AF sensors at infinity?

It would seem that the DOF is so extensive at that focal length, even at f2.8, that it would be nearly impossible to determine accurate focus. I don't think I've ever attempted infinity focus at 16mm on my lens. I'll have to try it and see what happens. Paul On Feb 11, 2009, at 11:59 AM, jtainter wrote: > My K20D came back yesterday.
