  • 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.

disappointing

  • Excerpt: The copy of the DA* 16-50mm I ordered was a huge disappointment. It front focused dramatically, and when it did manage to find focus, there was severe purple fringing. The overall image quality did not seem as good as my Pentax primes, even when neither of the above-mentioned problems reared its head. I returned my lens for a refund (thanks to B&H for making that process easy and stress-free).
  • Cons: Blurry Focus, Heavy

Unfortunately, a Piece of Junk

Retired in Idaho, B&H Photo

  • Excerpt: This is the second copy that I have bought in hopes that Pentax had cured their autofocus failures in the earlier units. I was wrong. To make matters worse, I also bought a K-5. I own two other DA* lenses and they are great! However, my new 16-50mm DA* started to fail on autofocus within 20 shots. The only smart move I made was to buy B&H's extended warranty. The first copy failed at 90 days and Pentax replaced it with an older (lower SN) copy. It failed 60 days later.

Very disappointed with f/4.0 and wider

Packer Bob, B&H Photo

  • Excerpt: I had high hopes for this product, but they didn't come to pass. I have a K10 and wanted a fast lens for low light so I could avoid using a flash. I used the lens after installing the updated firmware, version 1.31. While using the lens at a number of different events, I noticed that at wider apertures, for a significant number of the images, the main subject is completely out of focus. For some reason, the focus point ended up being somewhere in the background.
  • Pros: Durable, Rugged, Strong Construction
  • Cons: Blurry Focus, Heavy, Poor in Low Light

A Problem Lens

Greg Gilbertson, B&H Photo
30 October 2011
  • Excerpt: I photograph events so the 16 to 50MM is a great range for getting the shot without moving. I sent the lens in for repair during the first year due to the zoom locking. The auto focus was average at best and now hardly works. I will send it in for another repair. If the repair cost is high, I will probably junk it and go with Sigma.
  • Cons: Blurry Focus, Poor in Low Light, Slow Focus

auto focus has failed

jrak, Amazon

  • 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.
