K5 IIs AF problem
I have a K5IIs which I had kept unused (locked up in a cupboard) for about 6 months. Recently I took it out only to find out that the camera has developed some kind of serious focusing problem. It does not lock on focus even in the day light outdoor conditions instead hunts a little and gives up.
I tried with Pentax 100mm Macro, Tammy 18-250 and Sigma 12-24 all of these showing the same behavior. This should rule out problem with lens.
All these lenses (and even the camera) was working properly few months back. I have used this combo many times before, it used to work like a charm.
