Pros: Light weight, fast
Cons: Poor and noisy auto focus. Not better than the SMC 50mm 1.4
Sharpness: 8    Aberrations: 9    Bokeh: 8    Autofocus: 3    Handling: 10    Value: 7    New or Used: New    Camera Used: Pentax K-1   

This will be an unpopular opinion, but I don't think this lens deserves it's reputation. Before trying it, I was shooting with the SMC FA 50mm 1.4, a lens that I think is actually underrated. I was expecting to be impressed by the 77mm, but I found it to be overall a mediocre lens. It's sharpness and bokeh were about the same as the 50mm, and the auto-focus is terrible, like most of the film era lenses. I think that much of the praise of the older auto focus lenses comes from people who have likely never shot a modern camera with a modern lens. I was doing a demo of the Sony FE 85 mm 1.8 on a Sony A 7 IV at the same time, and the Sony lens outperformed this lens easily. When Pentax updated this lens, it should have gotten a modern auto focus motor. If you are on full frame, the SMC FA 50mm is about as good for 99$ used. The HD 50mm 1.4 totally destroys the 77mm limited. If you are on APS-C you are better off with the DA* 55mm. The only place for this lens is really film, and even then, I prefer the ?SMC FA 50mm.

This is lens just does not deserve it's reputation. It is sold on the nostalgia of older users.

Pros: small size, image quality, build quality, coatings
Sharpness: 9    Aberrations: 8    Bokeh: 10    Autofocus: 10    Handling: 10    Value: 8    New or Used: New    Camera Used: K1II   

This is my second FA limited after having the SMC 43 for a number of years. I like the improvements in this iteration, in particular the SP coating on the front element. Otherwise, it's all the same as before and that's a good thing. I even like having screw autofocus because it keeps the lens extremely compact and feeling similar to my 43. Perhaps my favorite aspect in terms of image quality is color rendering; in good light, everything pops without being too high contrast. It's very sharp, but has flaws in fringing, this lens really wants good light and then it is fantastic.

Pros: construction, very nice focus, size and weight.
Cons: purple fringing
Sharpness: 9    Aberrations: 8    Bokeh: 10    Handling: 9    Value: 10    New or Used: Used    Camera Used: k1, k70   

I'm a little embarrassed to be the first to review the lens here. I bought used this lens a few months ago to complete my trio with the 31 and 43 that I owned not in HD version. I had never used the FA version so nothing I can say about this comparison. The first thing I noticed is that the wonderful lens retains some defects that were already their own (at least from I read). The appearance of purple fringes in high-contrast situations has been highlighted since the first tests. It made me a little curious because I had not encountered these problems, or very small size for brothers 31 and 43. In real tests, however, the lens turned out to be for what it is. A great portrait lens (less for landscape but I don't practice it). its bokeh is truly breathtaking.

I haven't done the updates yet because I wanted to see if there were actually improvements by trying better on the two bodies.

It has a beautiful focus and I love the softness at the right point of the shots with very open apertures. Just close two to three stops and the lens becomes very sharp. I found a good reactivity of the af, especially on the k70, even on moving subjects like my dog. On k1 it is precise and effective on static subjects, a little less reactive on dynamic ones. It is a pleasure to handle and carry around. I am a lover of the 31 which remains my favorite lens for the greater use of my way of photographing, but I must say that for portraiture the lens has that very special fairy dust for me. I am very happy and satisfied. If someone hates the imperfections that may arise in certain circumstances, look elsewhere or may think they have spent their money badly. For all the others, I see no particular reasons not to swear eternal fidelity. I gave nine overall only because for me 10 only has 31, but I'm a fan.
I recommend the goal only that the option above leaves me alone no, I don't know why.
