As usual only boring pictures just to show some capabilities of this lens.
As many of you already know, the pictures taken with LTM lenses are always out of my Ricoh GXR-M 12MP/APS-C camera.
All pictures shot RAW and converted with minor adjustments in LR. However, no sharpening at all.
Resized for presentation with some crops for pixel peeping.

Overview infinity F5.6 followed by 100% crops center/right corner/left corner:





Some few meters distance at F4 followed by a 100% crop of the upper center:



Fully open for bokeh testing:


Only apprx. 1 m distance F5.6 (the wine is looking promising this year):



Infinity F4:



My final judgement is that this lens is certainly usable and doesn't show any major defects.
For the time being I am not able to tell how it compares to my 5 or 6 (not sure yet) other lenses in 28 mm.
The crop factor of my Ricoh turns it rather in a "universal" lens in 42 mm FOV equivalence (based on FF).
It's the predecessor of the presently available Ultron 28/2 in Leica M mount and was introduced in 2000.
Details of the lens can be found here:

Cheers,

Indeed. I am more than satisfied with all of my CV lenses and particularly this 28 mm one is almost perfect (for my taste). At least on APS-C/Ricoh GXR. Wink
