My Rikenon XR 50mm f/2 arrived. It's the steel (I guess that's the first) version. I guess similar performance can be expected from the later plastic versions.
Comparison is against:
- Auto Yashinon 5cm f/2
- Auto Mamiya/Sekor 50mm f/2
- Minolta MD 50mm f/2
First an infinity test @ f/2:
ComparisonF2 by devoscasper, on Flickr
Best center resolution from Rikenon and Mamiya. The Rikenon image is low contrast though and has a slight glow over it. Mamiya shows best center image.
Corners of 4 lenses are comparable. A bit glowy, with quite a bit of vigneting, but decent resolution actually.
Infinity test @ f/2.8:
ComparisonF28 by devoscasper, on Flickr
Most crisp center results from the Rikenon and Mamiya (check blinders on left window). Real high resolution. At his aperture, the far corners of the old Yashinon actually look the best to me.
Center image of the Minolta and Yashinon are comparable.
Infinity test @ f/4:

Differences are small, but Rikonon en Mamiya still have the best center image IMO.
Corners are difficult to judge: it's a bit of a mixed bag of results. I think the Minolta MD is best here in terms of resolution and contrast. The Rikenon also good, but with slight glow. The Yashinon has lowest resolution, but stays most uniform into the far corner.
Infinity test @ f/5.6:
ComparisonF56 by devoscasper, on Flickr
Center performance of all 4 lenses is comparable. Best corners of Rikenon, no glow anymore, very good resolution. Minolta is very close.
Infinity test @ f/8:
ComparisonF8 by devoscasper, on Flickr
Best corners of Rikenon and Minolta. Hard to chose.
Infinity test @ f/11:
ComparisonF11 by devoscasper, on Flickr
Centers are comparable. The Rikenon and Minolta have comparable corners. The Yashinon is not far behind; the Mamiya is a bit less in the corners.
Bokeh test @ f/2:

Draw your own conclusions.

Again, draw your own conclusions.
