Last night I tested the new lenses for focus adjustment. The DA* 50-135 benefited from a -1 adjustment. No big deal.
To my surprise, the DA* 16-50 needed no focus adjustment. Today I took the DA* 16-50 outside again to see if it still has the problem of not autofocusing to infinity at 16 mm. I first focused on a distant building, and it focused to infinity. Pleasant surprise. I then focused on some distant bare branches, and it displayed the problem of focusing only to just beyond the 2 m. mark. I then focused on a different set of branches and it focused to the far end of the infinity mark. I'll try to find time soon to give both lenses a brick wall test to make sure there is no decentering. If the 16-50 is okay on this score, then I'll just try it for a while, but checking to make sure that it focuses to infinity properly at 16 mm. It may still go back to Pentax to be looked at. Or maybe not.
