I purchased my Pentax DA*16-50mm and DA*50-135mm in November of 2013. I haven't really taken them out too much since but yesterday I was supposed to take pictures at my friend's wedding and the two lenses I took which were the 16-50mm and 50-135mm did not autofocus at all. I heard the high pitch sound on my 16-50mm lens but nothing was happening. Also the 50-135mm lens made no sound or even attempt to autofocus on my K5ii.
After taking the camera and lens home I thought it could be my k5ii so I put it on my k200D and still the same results.
Did I just have the dreaded SDM motor failure on both of my lenses on the same day?
I put in a quote request at the Ricoh repair website and it said $200 to inspect it. So I'm assuming $400 for both plus whatever they find out after inspecting it. Also does Ricoh honor any type of warranty repair even though it's been over 1 year?
I liked Pentax for their quality but it seems this SDM motor failure hasn't been completely fixed yet. Any thoughts from others experiencing the same thing?
The warranty is only good for a year, so you may be out of luck. The SDM motors tend to fail after prolonged periods of no use, so once you get the lenses repaired I'd recommend taking them out for a spin every once in a while. Ricoh claims that a design issue with the SDM has been addressed in newer production models and in replacement parts, but I'd still take the aforementioned precaution.
