If you can't figure out where Pentax's warranty repair center is, I'd also recommend Peachtree Camera Repair in Marietta, GA.
http://www.peachtreecamerarepair.com/ He was the second guy who tried to fix my Tokina 28-70 f/2.8 ATX Pro, and although he was ultimately unable to do so, he did show me exactly what was wrong with it & what (unavailable) part would be needed for the repair. There's also a guy in Knoxville who does Pentax stuff: http://www.pentaxs.com/ He was the first guy who tried to repair my Tokina 28-70. Nothing wrong with either of their work, the Tokina is just so old you can't get the part that needs to be replaced. On 9/28/2015 2:10 PM, Igor PDML-StR wrote:
Larry, Bipin gave an interesting idea. I had one experience with KEH repairing SDM. I had one used SDM lens purchased in early 2014 from KEH, and the SDM AF failed right away. I sent the lens back to KEH and they repaired it within a week or two. I don't know what they actually did with it. (Did they replace the motor, the chip?) In the past month, I have had 2-3 occasions when the lens wouldn't start focusing when I mount it on the camera, but then, after I turn the ring manually (no obstruction, even slightest is felt), - it starts working. I suspect it's at the verge of failing again. I have only one other data point for comparison: The lens where the SDM chip was replaced by CRIS under warranty, hasn't shown any problem over 3 years since the repair. In any case, I have too few data points to make any conclusions. But maybe those are helpful for you. Igor Bipin Gupta Mon, 28 Sep 2015 07:18:32 -0700 wrote: Hello Larry, suggest you try KEH. I have had some lenses repaired from them, though not SDM related. Rergards. Bipin camp: San Mateo, CA
