Good lens for Pentax cameras

Operate this lens very much on a Pentax K-5th At maximum aperture very soft, from Aperture 2 good sharpness, from 2.8 aperture very crisp. All in all, a good alternative to the DA * 50. Use it very much!

+ Good price / performance ratio
+ Good processed
+ Small and light
+ Faster AF
- Plastic housing (based on price / performance but acceptable)

All in all there is to the lens, even if the design already has several years under its belt, absolutely nothing to complain about. As already written, as measured by the price (it was some time ago for something under 300 purchased) the performance of the lens is very good. Anyone who wants to afford a (significantly) more expensive DA * 50 or Limited, makes nothing wrong here.
