Note: I think it failed due to my error of not turning the camera off during lens swap. Never had a problem prior to or after that one time, but I cannot specifically verify whether it was my fault or not because I don't remember whether I turned the camera off during swap or not. so I'm not considering this a real lens failure, and it has worked flawlessly since.

Which ones have failed after SDM repair?
N/A

If it failed on you would you send it in for repairs? If no, why?
Yes for all

No. Mechanical parts fail, sometimes with greater statistic probability and sometimes not. Sometimes you get a lemon, sometimes you don't. Now if they said it was not a warranty repair, I might make a little noise, but on the whole I expect repairs to be the cost of owning anything. Overall I'm happy with the quality, build, and performance of these lenses. Most of the photographs I get the most compliments on are taken with my 50-135.

50-135

Which ones were bought used and which ones are bought new?
50-135 new

How long have you owned which ones?
50-135 for just about 2 years

Which lens have not failed on you?
50-135

Which ones have failed on you once?
none

Which ones have failed after SDM repair?
none

If it failed on you would you send it in for repairs? If no, why?
Yes - it's a great lens optically, and I like the AF (if a bit slow) - but even MF it rocks!

If one failed on you, how would that change your view on Pentax if it does all?
Not at all. It's a consumer good and I got it for a fair price for what it does, so I also got a warranty with it to guard against mechanical failure, the same as with any expensive electronics purchase. Not sure how I feel about it only being electronically controlled on my current camera, since it is a lens and I expect to keep it for a good long time... but until recently the same could be said for camera bodies which currently cost as much as this lens and yet people are surprised if someone uses the same one for 6 or 8 or 10 years without "upgrading."

Not sure. Yes, I would be displeased, but I know that most companies have occasional issues with QC to save a $ or two.

Which ones have failed after SDM repair?
none. I haven't sent it in for repair (yet)

If it failed on your would you send it in for repairs? if no, why?
the 50-135 failed once. It now squeaks but focuses. It is out of warrenty so until it fails again (or I get fed up with the noise), I'll live with the noise rather incur the expense and time.

If one failed on you, how would that change your view on Pentax if it does at all?
I've been a loyal Pentax customer since the ME, but I do hesitate to buy another SDM lens. That is very unfortunate since the weather-seals are a main attraction for me.
