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.

Pros: Sharpness, lightness

Cons: Low quality materials

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.

Pros: Price, size, sharpness, brightness

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

Pros: Low price

Cons: Unable to open all-open focus

Opinion: Comes enticed by modest cost and good brightness. In practice, I can not use it at All Opening because it fails to matter properly. Working on the front / back focus (inconvenient since it is run by an eastern program where you have to enter and exit in a less practical way) the problem (to a lesser extent) moves to the other openings that being more closed benefit from the Depth Of Field greater. Bad buy but maybe the K10D camera in part could be guilty considering the proper fb / focus adjustments with all the targets though not with such poor results.

Pros: Sharpness, light, color rendering

Cons: perhaps too much plastic

Opinion: Great 50cc Pentax. I use it for outdoor portraits / studio and still life and is a great goal. The color rendering is excellent and as good contrast. Precise focus and detail very very good product. The construction is made of plastic (including attachment K) but it just will not be as delicate as King Kong and there will be no problem of mechanical reliability. Great bokeh at f2.8 (in rare cases go under, but by choice).

Pros: Clarity, weight, contrast, color

Cons: plasticky, noise autofocus

Opinion: I own this lens for about eight months and are satisfied with it. I mainly use it for portraits and low-light situations. Things I have been hit are the sharpness this lens is able to produce, contrast and brilliant colors. Not the best optical Pentax but certainly I noticed a significant difference compared to 18-55 by kit, in the positive sense of course. So, overall, I am fully satisfied and the only flaws I see are the construction plasticky and the annoying noise of the autofocus; but you can not have everything in life ...

Pros: great sharpness, accurate focusing

Cons: rather expensive compared to the competition, autofocus noisy, lacks the AF / MF switch on the lens barrel

Opinion: I have this lens recently, but so far I can only name a bene.rnGrazie to its simplicity is very sharp even wide open, and vignetting is barely visible, but it disappears already at f / 2,8. In my case, using a K-5, I had to work with great attention to fine-tuning autofocus because it showed some back-focus, but once it's done me no more problems since. To detect the noise a bit 'annoying autofocus, which is not recommended for use on stage and in the environments silenziosi.rnLo I exploit very well in night photography, focheggiando manual with the live-view, and I must say that the lack of the switch on the barrel is an inconvenience because it forces you to use the lever on the body macchina.rnInfine the price rather high compared to several competitors, who more often than not also cost € 50 less, or at a similar price offer an aperture of f / 1,4.
