It varies.With the long lenses, I start by setting it for the mid range, then check to see how accurate it is at the focal length I use most. With a wide to mid range, it’s easiest to see differences in focus at the long end, so I set it there, then check for the mid range. The DA* 16-50 needed a plus 4 adjustment. That would be enough to make it seem soft without correction, and backfocus isn’t always easy to recognize in daily use. Most of my lenses required no adjustment with the K3, so I’m going to recheck the DA* 16-50 after using it for a while, but I think I nailed it at plus 4. Each generation of Pentax cameras has seemed better than the previous in regard to not requiring a lot of adjustment.
