My DA*16-50 is currently at CRIS for SDM replacement.
The repair bill = $195 [includes return shipping & 6 mo. warranty]
It was about 6 months beyond end of the warranty period
.
I sent the lens in on July 12th, so it has been gone just over 4 weeks so far.
I got the repair invoice on July 25. The CRIS repair includes a 6 month service warranty.
update 8/18: CRIS just charged my CC, so that means the repair is finished and the lens is on it's way home.
update 8/19: The lens arrived last night. It performs just like new. Auto-Focus is performing flawlessly again. Cudos CRIS!
