Lens Review Date: May 24, 2021 I can recommend this lens: Yes | Price: $1,111.10 | Rating: N/A 

 
Pros: Sharp enough, bokeh is nice when wide open
Cons: Vignettes under f2.8, some purple fringing below f3
Sharpness: 9    Aberrations: 8    Bokeh: 9    Autofocus: 9    Handling: 10    Value: 7    New or Used: New    Camera Used: Pentax K-1 II   

A brand new 20 year old lens. Must be knocked down a few stops to avoid pretty poor vignetting. Purple fringing is visible in high contrast areas, but not too bad even wide open, pretty gone after about three stops. Must use camera body switch to change into manual focus mode, you cannot just override the focus by turning the lens. If you want a prime wide angle for your K-1 then this does get you the best one available from Pentax, but still can't be used in the care-free way the state of the art D FA 50 1.4 can be. In return, it's not the size or weight of the 50 either.
Remember to update your firmware before use.
