The Pentax 18-135 and 17-70 are both very quiet.
Much quieter, in fact, than the little 'bzzt' the K-5 makes when you switch it on.
I've had these only for a few weeks in total, so I can't comment on how reliable they are if unused for a long time.
Obviously the 18-135 will be more 'general purpose' simply because of its greater reach, but careful of the edge sharpness.

As Chris says both the 18-135 and the DA 17-70 are extremely quiet.
Since the 18-135 uses a DC motor rather than the "dreaded" SDM it should be reliable even when left unused for a considerable length of time.
Having said that I have never had a problem with any of my SDM lenses and a couple of them aren't used for months at a time.

Hmmm, i did not consider the DA 17-70 because I thought the Sigma 17-70 is was a better alternative ( smaller/lighter/close focus)
I must say, I am leaning towards the 18-135 WR

I would love to have an 18-135mm, but it will just have to be added to the list. The lens is virtually silent and one of the fastest focusing I have used.

Did you have to give your review copy back then? That's a bit mean!

I would be cautious with DA 18-135 as it has horrible reviews on photozone as well as user reviews on pentaxforums. And the dreaded SDM issues might be an overblown problem....anyway 17-70 looks to be a very decent lens

I do think SDM has improved, as I don't seem to read as many horror stories as I used to. Didn't someone mention a professional's blog where he talked about Pentax changing the SDM motor design and fitting an upgraded one to any lens sent in for repair?
