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

Oh and just out of interest, did you get infinity on APSC?

Don't suppose it matters too much, as i've found I don't even need infinity for astro photography, let alone portraits!

Due to the "character" of the lens it most certainly is not usable for Astro-Photography (or landscape or architecture for that matter). So in my opinion it isn't at all important if it's usable at infinity. I is an interesting choice for portraits or macro-ish (flowers etc.) subjects.
