Pentax DID come through!

Pentax received my DA* 50-135/2.8 on the 16th. Today it arrived back here. No charge. Here are the appropriate comments from the shipment. I mounted the lens, and we have snappy (for Pentax, of course) AF again.

RE-DO

GEAR PLATE A ASSY
AUTO FOCUS SYS ADJUSTED
MOTOR REPLACED

TOTAL Parts 0.00
INVOICE TOTAL 0.00

Congrats Albert! I am glad to hear the good news. I am just curious what is the problem with your 50-135 before it got repaired (the 2nd time)?

It was the standard SDM failure - would not AF when first mounted on the camera, requiring minutes of fiddling with the focus ring to get it going. It was first sent in with this problem, and Pentax tried adjusting things, but that did not work. It started acting up again almost immediately. I contacted them, and got the OK to send the lens in. They did what they should have done the first time around, replaced the in lens motor.

I currently have the 50-135 and no problem so far. The SDM just works fine, sometime it take a bit longer to focus (1-2s) but still working

They don't all break, for sure. My DA* 16-50/2.8 has never even twitched, and it has taken 44% of my shots with the K10 - almost twice as many as the 50-135. Mine did break, but shortly before the 2 year warranty ran out. I sent it in, along with the camera which needed repairs (not warranty - don't drop them hard enough to break the top plate!). It came back with the same symptoms, after the warranty had run out. I asked for, and received a re-do on the warranty fix, and they returned the lens very quickly. I am pleased with the second go around.

I would like to add that even if the lens were not repaired, it is superb optically and would lose nothing of that when use in MF mode. I like it very much. I admitted same to Pentax - worst case I have a very, very good manual focus lens.

Very good to hear

Excellent Pentax Canada

I'm hoping for a 50-135mm myself once my CRA comes though.
