Digital
Pictures taken with a Canon 500D at ISO100 and I used a M42 to Canon mount adapter
The aperture ring on this lens unfortunately hits the Canon M42 mount adapter so I couldn't focus to infinity.

Build quality

Really good!
Robust and got a nice feel to it.


Conclusion

Great lens!
Nice and contrasty at all apertures.
Really good center sharpness but you have some corner softness and not that great flare.
Another thing is that the aperture ring have a little edge that will hit if you try to use this on most m42 mount adapters.
This will prevent you from focus to infinity.
So you can't use this lens on most modern cameras unless you file down this edge.

Thumbs up:
Center sharpness
Contrasty
Build quality
Nice bokeh

Thumbs down:
Flare
Can't be used with most m42 mount adapters.
