Pros:Light, good value for money, sharpness in general, good yield all over the frame (f2.8 onwards), blurry, autofocus
Cons:Limited sharpness range f1.8-f2, plastic attachment
Opinion:Tactasi of economic alternative for portraits but with good value/quality price. CONSTRUCTION: Plastic (also the attachment...) and light. Although the external structure is made of plastic, the elements are well fixed and do not have any play that can compromise the optical yield (diffraction, out of focus, etc...). I mean, it looks like the internal mechanics are good. OPTICAL PERFORMANCE: - sharpness present only in the center in the range f1.8-f2.4 with a pleasant blurry that makes it suitable, in my opinion, for artistic photos; - reaches a good level of sharpness over the entire frame already at f4; - at f8 you have excellent sharpness It generally has a good contrast. AUTOFOCUS: Because of the little mass it has, it turns out to be fast.
Opinion:It is in my opinion the Pentax lens with the best value for money. I was often amazed by the three-dimensionality and the colors. From a low end lens one does not expect much, this instead amazed me. Always keep in the bag for any eventuance. I don't find any big flaws except that it's all plastic and sometimes it's noisy in the focus.
Pros:Price, size and weight, yield from 2.2 onwards
Cons:Plastic connection, very noisy autofocus, longitudinal AC in out of focus areas
Opinion:Taken for a friend and tried on the fly, is the 50ino honest with which to start experimenting a little on the portrait (and not only) on APS-C: A ta you see a bit of coma (in vintage style) but just close a little and from 2.2 the lens behaves quite well , in any case there are longitudinal AC (green in the background and red in foreground) in the areas out of focus but not particularly annoying; In short for the price there is everything... Sin attack plastic bayonet (CMQ weighs little) and the AF slow and noisy.. Too bad it's not WR.
Cons:For someone I would say the plastic attack, autofocus a bit noisy, not WR, not quick shift
Opinion:Recommended for anyone who wants a fifty bright AF cheap (if one does not have problems with manual focus then I would recommend the Pentax A50 F 1.7). I was very impressed by the rendering and the sharpness of the image at the brighter openings. Sometimes it tends to have problems of front/back focus easily correctable in the car since almost all the Pentax machines allow it, except the old entry level. The plastic attack I have never found a problem since it is very durable and does not creat or anything. If he had the quick shift or at least been a WR it would have been even better since they were technologies already put at the time on the 18/55.
Pros:Price, size, significant performance in relation to the cost
Cons:for the price none
Opinion:Purchased for low-cost portraiture, I had to ask for the replacement because of problems of front / back ficus and chromatic aberration, evident at larger openings.rnThe new article was extremely bright and usable already af 1.8, with excellent color rendering and chromatic aberrations almost nulle.rnLent quite defined and clear, with excellent rendering of details.rnThe autofocus is fast and accurate, although noisy compared to the standard lens 18-55 (kit of my K-50), becomes slow with light poor, but always hooks the subject well.rnPeccato for the plastic construction and the fact that it is not WR, but for its cost I would say that money is really well spent.rnConsigliatissimo, and indeed, mandatory, for those who want to take the first steps between the fixed and experience a beautiful bokeh without fainting.rnrn
