Re: SDM issue????


The SDM motor failed on my DA*16-50/2.8 after about 1500 shots. That's a first hand account and not hearsay. I could still use it as a manual focus lens and I could still use it on my *ist DS, but I could not use it on the K10D.

I sent it to Pentax USA 3 weeks ago. A replacement lens arrived today. I've taken a dozen shots with the new one, but I haven't had a chance to put it through its' paces yet, but it seems much more quick and responsive than the previous lens, even when new.

My DA* 50-135/2.8 is still fine, but I've not used it as many shots as the other. I do know that Jim's (Rupert) 50-135 is also at Pentax USA for a similar failure. I love my DA* lenses and I'm not sorry I bought them. I just hope they can figure out what the problem is.
