I have a question for those people who had SDM (or in general, lens chip) failed and replaced.
I see that with one of the SDM lenses my K5 has the aperture and speed settings rapidly (as in crazily) fluctuating. (And the focus shows "MF", regardless of the focus selector position.) I was wondering if this is one of the symptoms of the failed chip or that could be for a different reason. When I had a previous chip failure, I didn't see anything like this. When the chip failed in your lens, did you see this type of a fluctuation? I wonder if could be something else that happened to the lens.
