  • Excerpt: I guess I got stuck with one of the bad ones. The AF is locked up right out of the box and not functional. As for MF it seems quite nice - but not really going to test since I have to send back. There really seems like it is a mixed bag for this lens. I have found quite a few reviews that have this lens' AF functionality failing quite often. For the price, Pentax should really do better. I love every other Pentax lens I own - This one left me quite a bit disappointed.
  • Cons: AF does not work

It broke immediately following the return period.

  • Summary: Lens was perfect. Not a mark on it. Performed faultlessly, until 30 days after I got it, then focusing motor quit altogether. Now I wonder how much repairs will cost. Hope that "great price" I paid plus repairs is still less than the cost of a new lens.

Looks great, arrived non-functional

  • Summary: Bought this lens to go with my wonderful Pentax DA* 50-135. Unfortunately the lens that was delivered did not work right out of the box. The focus is stuck at infinity. When in AF the motor makes a quiet squeaking sound as it tries to change the focus but that is all. When in MF the focus ring turns but the elements do not move. Evidently Pentax is still having quality control issues with this lens.

auto focus has failed

  • Summary: I have been using this lens with a K5 in Alaska to take moon-lit night landscapes, in temperatures as low as 20 degrees, for periods as long as 3 hours. Of course I only manually focus-- I haven't even tried to auto focus at night. Shooting in raw mode, the photos are amazing. They look too much like daylight photos.

Dead

  • Summary: I bought this camera in June of 2009 from Amazon. At first I was very impressed with it; it's a great focal range and the fact that it's f2.8 throughout that focal range is wonderful. However, I was never quite satisfied with the pictures I got from this lens, even during optimal conditions (bright sunlight, outdoors)--they always seemed a tad out of focus. I have never before paid this much money for a lens, and I guess I expected excellent results.

Bad quality control

A. Arena, Amazon

  • Summary: After buying this lens I noticed that most pictures were "soft" on the right side. Not on the left. I then did some more specific testing at all focal lengths and aperture values, and found out that the lens was decentered. This lens has had a very big quality control problem that you can read about all over the net. I thought I might get lucky, but I was wrong. Luckily I bought it from Amazon. They have such a great return policy.

Bad QC

Frank Wolffe "HaventGotMyStuff", Amazon

  • Summary: I'm very disappointed with this lens. The subject of every picture I took on my K10D with this lens was out of focus when shot on auto. The focal point seemed to be 3m behind my subject. None of my other lens have this problem. My DA* 50~135 consistently hits focus on the target and is ridiculously crisp. I could manually focus on my subject and produce a reasonable image if the aperture was dialed down enough, but the point of this lens is the ultrasonic auto focus.

Massives Qualitätsproblem

thomas, Amazon

  • Summary: Nach Rücksendung des ersten Objektiv wg. erheblichem Back-Focus leidet das Ersatzobjektiv an SDM squeaking (siehe Pentax Forum). Beide Modelle weisen eine hohe Seriennummer auf (Status Nov. 2011) welche entsprechend der Serial DB im Pentax Forum eigentlich nur noch vereinzelt Probleme machen sollten. Im Vergleich zu den Ratings mancher Kit Objektive ist man bei Pentax offenbar besser aufgehoben im unteren Preissegment zu investieren.
