I have the * 50-135mm. It failed a few weeks after the warranty period. The SDM died. Until that time I have not used it for more than a couple of times (less than ten, I believe). Unfortunately, Pentax strictly forbids using it as a screw driven lens on recent bodies. The screw drive mechanism sits there in perfect order but this does not make one happy!
Optically, it is simply superb. Ergonomically, it is fine. Autofocus is not stellar (slow), SDM (at least as implemented on this lens) is terrible. I have dropped mine a few months after it was fixed in Germany. Now, it is my most expensive manual zoom lens :( Bulent --------------------------------------------------------------------- http://www.flickr.com/photos/bc_the_path/ http://photo.net/photodb/user?user_id=2226822 http://www.pentaxphotogallery.com/bulentcelasun 2011/5/11 Bruce Walker <bruce.wal...@gmail.com>: > On 11-05-11 2:06 AM, Brian Walters wrote: >> >> G'day all >> >> My son is looking at this lens for his K20D. >> >> The reviews look good but I'm just wondering if anyone here has any >> experience with it. > > Brian, I can't recommend it more highly.
