Pros: Lightweight, robust, sharp images, bokeh

Cons: No AF

Opinion: I bought Pentax because I already had lenses that my father used in an analog, including this one. First of all, I am first of all a landscaper, so for this kind of photo this lens is not ideal because it cuts the image too much, but I use it for portraits and I must say that it does its job very well. Sharp images and a bokeh that has nothing to envy to other lenses. On a constructive level and very solid and light. Unfortunately being an old lens does not have AF, in fact the first times I had difficulty in focusing. All in all it is a lens to have if you are not a beginner.

Pros: Price, compactness, bokeh

Cons: Chromatic aberration, poor sharpness

Opinion: Used for a short time, I was disappointed not a little. Manual fire is inaccurate, image quality is barely acceptable. Not recommended for those who do not have experience with manual fire and vintage furniture. Suitable for portraits and macros (when used with the specially made inverter ring), but absolutely not subject to long distances and landscapes. Chromatic aberration makes it almost unusable in backlight

Pros: Bokeh fantastic, small, easy to manage manual focus, three-dimensional image, already at f3.5 image detail is impressive, precise ring with the right resistance.

Cons: For those who start doing photography, manual focus can be complicated, no photos to landscapes (size too and it is not clear to TA as all other objectives so open after all, lose detail at the edges to TA in a landscape)

Opinion: Purchased this lens because I wanted a fifty "pushed" manual, I had the pleasant surprise of sharply focused images, many friends have apprezzato.rnCattura lots of light (being a f2) with a bokeh effect impressionante.rnPosso say that to understand the love that is born, you have to try it, and that if used on Pentax as usual, delivery stunning image seen by few lenses simili.rnPeccato you landscapes TA lose much sharpness, and the edge is not detailed, but we all know that opening is so high almost always the case, and for landscapes would never use a 50 mm because it cuts the image too much in my opinion, for the sharpness and details just get to F4.5 / 5.rnin Summary: macro, Si Portraits, No paesaggi.rnrnPer Finally, excellent lens, is located at little expense, great for advanced photographers since it's only manual AF nothing
