Anyone else had this kind of problem? Anyone know how long the (UK) warranty period is on DA* lenses?
Yes, I had two from early batches that suffered focussing problems after varying lengths of time. My third one is fine. Fortunately I bought from SRS and the two duffers were replaced without any problems.

Standard warranty is 1 year. If bought from a Pentax Pro dealer its 2 years. If bought used, none at all.

You could make the 'fitness for purpose' argument if you bought it new from a recognised dealer. Claims can be made up to 6 years but after the warranty period, the onus is on you to prove that the item was inherently defective from new.

Which shouldn't be a problem, since you can get info about that problem on hundreds of post on the internet.

yikes i just bought an sdm lens!!!!!
Whilst accepting that some people have had proplems with SDM. I have a DA*16-50, DA*50-135, DA*55, DA*60-250, DA*200, DA*300 and have had no problems with the SDM on any of them using a K10D, K20D and K-7.

Each of these lenses (except the 300) was bought as soon as they were availlable in UK so are early versions of each model (e.g. DA*50-135 bought Sept 2007 and the DA*16-50 bought Oct 2007).

A few percent of people who have had SDM problems make an awfull lot of noise about it and in my oppinion are unnecessarily downing the product and scaring of new buyers.
Good luck

We did have a non-scientific straw poll about this a while back. Sadly, I am one of the people for whom the SDM failed and as I have only one SDM lens that makes it a 100% failure rate.

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

I had my AF Motors replaced on both my 16-50 and 50-135. My 16-50 was acting up and the new motor works perfectly now. I was told that it is the newer version AF motor. I had the 50-135 AF replaced just in case.

I have very occasional (and I mean very occasional) AF issues with the 50-135mm, where is will not focus in either AF or MF. However by switching the lens with another and switching back, it works. It is a fault, but not to a point to affect me at the moment.
