Re: RO109-1A - adapted to m42

I recently got a copy of this lens, adapted to M39, and with an added aperture.

Some pics I made wide open:

Even on APSC, there is very substantial distortion at the edges and corners. If you want a subject with some semblance of sharpness, it's recommended tot put it near the center of the frame
