When I mount the DA* 16-50 F2.8 on the K20D and focus on something far away, the autofocus will move the focus point to just short of the 2 m. mark. It won't focus to the infinity mark. If I manually focus to infinity, distant parts of a scene noticeably sharpen up. If I zoom to 50 mm, the lens autofocuses to infinity just fine.
The lens works just fine on my K10D. Does anyone know if/how the K20D's autofocus adjust works for zoom lenses that focus correctly at one end of the zoom range, but not at the other end? I suspect that I have a defective K20D, and that I have to send it to Pentax.
