Pros: Impeccable (metal) construction, small and light, always sharp in the center, aperture ring

Cons: Autofocus to be adjusted well in-camera, price from new

Opinion: Taken used but like new in black version, it is a lens that does not disappoint, if used correctly. It's not very suitable for action photography even though the autofocus is quite fast, but in ambient portraits or wildlife photos it's some of the best I've ever tried. The important thing is that the autofocus is well calibrated through the in-camera fine adjustment, because with an aperture of f/1.9 getting the part of the subject in focus wrong is a moment. However, it must be said that in the center of the frame it is always sharp, regardless of the aperture, the detachment of the out-of-focus planes is very nice and personally I prefer to use it at short distances to bring out its character. The presence, far from obvious, of the aperture ring for a possible totally manual use is appreciated, and in general the metal construction, even if the lens remains small and light. Grafted onto the K1 it almost disappears, even leaving the small screw-on lens hood mounted. It's not cheap, but if you find it used and if you have a certain idea of photography, it's worth having

Pros: Really pro construction. Pretty fast, build quality, light, sharp, aperture ring available, remarkable center sharpness

Cons: Lack of tropicalization (from what I understand).

Opinion: Tested on KP and K3 III monochrome. For portraits and photos of the figure I find it an excellent lens considering that I am not a professional but a medium-low range amateur photographer I am not well enough to define the chromatic aberrations that it could introduce.... obviously even less on monochrome.... having said that... The sharpness in the center is exceptional from f/1.9, and maintains a fairly soft blur and offers a very good three-dimensionality in my opinion, The vignetting is present at full aperture, but it contributes to the charm of this lens that winks at vintage
