That Rikenon is really producing some great results.

I had the 49mm-filter-thread version and it was quite poor. Pretty sharp in the centre wide open but the edges never got really sharp, even at f/8, and that was on APS-C. It's a lovely lens to use simply because it's a Takumar, but optically not great. My M 35/2 is better.
The larger filter thread version may be better, but I haven't tried it.
