I like this little lens. It was the first lens I bought for my X-T20. The ONLY thing that's been bothering me is the heavy purple fringing it produces. This lens has WAY more fringing than ANY other lens I have used on this system or my old Pentax system. Other than that, it's great for sharpness, size, weight, handling, etc. One downside vs. a sea of positives makes it a pretty good lens if you keep in mind this one weakness and shoot accordingly.

I have to say this was not my experience at all with this lens. I don’t recall it producing any CA (or certainly none that I noticed).
I’d add that this is probably one of Fuji’s best primes (for the money) with no flaws to speak off. Super sharp right through the aperture range (until diffraction set in), superb micro contrast and blazing fast AF. The only reason I no longer have one is I wanted something faster - so I snapped up the Sigma 56mm as soon as it was released.

RedDog, the only way it would show visible PF or CA is if you were processing a RAW without the Fuji profile - and even then it should be hard to spot. Certainly on C1, it is totally corrected. I have several Pentax lenses (majority of them film era though), and they all show far more PF than the XF 50f/2. You might have a defective sample, unfortunately. Do you see any softness to one side when shot wide open?

My sample is easily the best overall Fuji lens I own (two zooms, four primes), although none of the other five are less than "good" optically.
