DA*16-50 focusing test

Starting to sound like a serious issue...

...well now we have 3 reports of the same problem. Now - sure every once in a while the AF will be off - that is a given but this much inconsistency is unacceptable IMO. Now I am starting to wonder if the lenses SDM's were underdesigned somehow? Have badly calibrated AF mechanisms? A body + lens issue? A firmware issue? Whatever it is Pentax should take note and do something about this.

Also, I still have my doubts of this being a universal DA*16-50 problem - there are quite a good amount of users of this lens now who I think should have noticed something strange if all lenses had this issue. Interpix - is your AF as inconsistent as mine? (ie. at all focal lenghts, close focus, long focus, etc.?)
