SDM failure is real and there is a cure

  • Summary: What you have been reading about this lens are mostly true. SDM failure being the biggest issue. When I was doing my research, I read something like Pentax has addressed the issue (though never officially announced) and you will be fine. Not true!

This lens is killing me

JP, B&H Photo

  • Excerpt: Optics are fantastic and no complaints there. The problem is the AF. It only works when it wants. I am on my third lens and same problem every time. Well, the first one the AF never worked, second was great and then a week later died.
  • Pros: Nice Bokeh, Sharp
  • Cons: Af Problem, Poor in Low Light, Slow Focus

Really don't worth the price and the DA* sign.

Ford, Amazon

  • Summary: I was willing to get this lens because it has a DA* sign on it, which make me think it should be one of the best lens produced by pentax, however, I was wrong. In order to get this lens, I sold my 17-70 f4. This is really stupid action and I really regret doing that. It looks pretty good right?

Unreliable mechanics

Pete, B&H Photo
8 September 2011
  • Excerpt: The results are outstanding when the lens works. Unfortunately I had the SDM fail for the second time, with less than one hundred shots. The lens was used only in benign environment, never abused. At [$] per repair, it's not sustainable.
  • Pros: Nice Bokeh, Sharp
  • Cons: Backfocus, SDM failed twice

Good optics, weak mechanics

Reviewer, B&H Photo
4 April 2011
  • Excerpt: Sharp pictures, good colors; some chromatic aberrations at 16mm. Big problem is, that the autofocus motor died in the middle of a vacation. The lens is now off to Pentax for warranty repair. My experience, unfortunately, is in line with other users' experience in that respect.

unexpected inner focus

  • Pros: Metal Mount
  • Cons: Blurry Focus, Expensive

Dud if you ever saw one!

Anton Punt "AGP", Amazon

  • Summary: The lens initially really impressed in build quality and the packaging was good. The moment I started shooting however it was evident the lens consistantly focussed behind the focus point. This is very dissapointing!

Nice while it worked

Cesar H. Perez, Amazon
27 May 2010
  • Summary: As with many others my SDM died. The lens will no longer auto-focus, only works on manual. I guess I'll send it in for repair or buy something else. It did take beautiful pictures while it worked though so I'll give it 2 stars.

Disappointing

Robert Petkus, B&H Photo
24 April 2010
  • Excerpt: I tortured myself over the purchase of a high quality zoom that would compliment the focal range of the DA* 50-135 f/2.8 (I own this lens and am more than satisfied in all aspects). Another candidate was the Tamron 17-50 f/2.8.
  • Pros: Durable, Quality Construction
  • Cons: Chromatic aberration, Soft wide open, Vignetting

I sent the first two back

George E. Robertson, Amazon

  • Summary: They are still having problems with quality assurance. This lens arrived and it looked great. I took several test images of a large 2 foot square black-on-white ink line drawing. It had sharply defined ink pen lines all over it, all the way to the edges.
