Pros: Sharpness, build quality
Cons: None unless you don’t like manual
Sharpness: 10    Aberrations: 10    Bokeh: 7    Handling: 10    Value: 10    Camera Used: K-30/K-50   

I lucked into a copy of this lens in a thrift shop without knowing anything about it other than it had a K mount and a nice feel to the construction and smooth focus and aperture rings. It was also in mint condition. Who would argue with $10? On APS-C it is a great normal lens and fantastic for just walking around and taking snapshots. Also handy for my old K-1000. I had a chance to try Ricoh’s GR once and I would put this Rikenon on my K-50 up against a GR for sharpness any day. My only negative observation is the zone focusing scale doesn’t seem quite calibrated to my digital bodies. I’m not technically savvy enough to understand why that might be. In any event, it is certainly the sharpest prime I own to my eye, vintage or otherwise.

Pros: Sharpness
Cons: No "A" setting
Sharpness: 10    Aberrations: 9    Bokeh: 7    Handling: 10    Value: 10    Camera Used: Pentax K10D   

I've bought this nice piece of glass for 8000 HUF, which is about $29 currently. It is fully manual, without an "A" setting. It has a 52mm filter thread.
The focusing ring turns 90° and does so very smoothly. I received it without a front cap, but that is easy to replace... otherwise mine is almost like new. This lens is already fairly sharp wide open. Stepping down a bit improves it even more. I didn't notice any visible distortions. It's a nice replacement for my 18-55mm kit lens for landscapes, which is hardly sharp and also has nasty distortions.
All in all, this lens fulfills its intended role in my gear as a wide angle lens, and I already like it pretty much.

After about one year of using this lens, this has became my go-to landscape lens. This lens is just so wonderfully sharp at all apertures, it's amazing!
Put it on a film camera and you got an UWA lens. Put it in an APS-C camera and it becomes a good normal. Either way, for landscapes, it is amazing!
