My DA*50-135 had been behaving erratically, refusing to AF-C and often refusing to lock focus with AF-S too, even under excellent high contrast situations.
It was also making squeaking noises sometimes when hunting for focus.
It's still under warranty, so gave it to Kevin for a checkup last week, and today, I learned that it has gone to Japan for repairs. It will be 4 weeks before I get it back
There are quite a few failures reported on DPreview for both the 16-50 and 50-135. The 300 and 200 primes seem to be relatively immune so far.
Anyone here have problems with their SDM lenses?
