Thinking about 7Artisans lenses on GXR + A12 M mount module.

I wonder if any of you GXR + A12 M mount module users have tried out the 7Artisans 50mm F1.1 or 35mm F2.0?

I'd like to know if these Artisan lenses are compatible with the A12 - do they fit correctly without touching the shutter curtain.
I understand that they are soft wide open but sharp at F5.6, but would really like to know how you rate them.

(I already use the GXR + A12M + PK-LM adaptor to use with my many Pentax lenses and am now looking for an affordable lens to connect directly to the A12 without need for an adaptor).

Many thanks for any feedback you can give me.
