This lens is killing me

JP, B&H Photo
23 June 2014
  • 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. Now after a few months it started acting up, then ok for a while and now just refuses to work. The photos are sharp and I love the output, but Pentax cannot get this lens right. They should take it off the market and FIX the problem.
  • Pros: Nice Bokeh, Sharp
  • Cons: Af Problem, Poor in Low Light, Slow Focus

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

  • 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? an upgrade from f4 to f2.8. After taking some pictures I discovered lots of problem. 1.

  • Excerpt: I've found this lens to have great build quality and the weather-sealing is a boon in a damp climate. The autofocus isn't the fastest but it is fast enough and accurate and I've had no problems with it. There is more flare and CA than I was expecting, but then as with any lens these are only hassles if you are not prepared to work around them and/or correct in post.
  • Pros: Build quality, performance at f5.6
  • Cons: CAs, poor to very poor below f5.6

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. I also experienced back-focus issues, that were not consistent over the zoom range. Pentax fixed that under warranty as well.

unexpected inner focus

Skytree, B&H Photo
26 January 2011
  • Excerpt: using Camera: K-7 situation: inside of house with natural light/fluorescent lamp I did not expect that the length of the lens became extended as I recognized that this lens was inner focus type. When I try to change the focal point distance from 16mm to 50mm, the lens is getting extended by about 10cm. For focusing, it is too difficult to focus accurately with AF. So my feeling is a kind of disappointed.
  • Pros: Metal Mount
  • Cons: Blurry Focus, Expensive

  • Excerpt: My experiences with this lens have been negatively traumatic, to the point where I have the dreaded "Fear of Using this Lens" syndrome. Sure, if I am in snapshot mode why not. But considering that it failed for me after it had just had a new motor installed of the newest generation (apparently) before I began my shoot for Harper's BAZAAR Magazine. NO WAY JOSE...
  • Pros: Optics are excellent BUT...
  • Cons: SDM failure is endemic

Dud if you ever saw one!

Anton Punt "AGP", Amazon
22 August 2010
  • 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! With subjects 3-4 ft away the focal point is between 2-4 inches behind and on portraits 6-10ft away the focal point is between 2-4ft behind! PENTAX very disappointing!

  • Excerpt: seriously, mine was the worst copy of any pentax lens i've ever used. i was so looking forward to it as a companion to the 50-135 (which is a very fine lens). i have both new and old primes and quite a few zooms from various manufacturers, and this particular copy of this lens was just awful.
  • Pros: nice range, weather sealed
  • Cons: CA, barrel distortion, intense contrast, focus hunting
