Showing 1-10 of 14
Really don't worth the price and the DA* sign.
16 April 2013
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.
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...
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
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.
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. The images showed that the focus was unacceptably out of alignment from left to right and also a bit out from bottom to top.
Summary: The built quality is exceptional. sharp, smooth and fast AF. Be sure to update your k10D firmware to v 1.3 before using this lens, so you wont be like me at first scratching my head wondering why a lens this expensive is noisy and vibrates. The lens is made in vietnam-nothing wrong with that, for some reason I was under the impression it was made in Japan. 7/16/11 Update This lens did not last, been repaired/replaced twice already because it quit autofocusing.
