Leica thread(screw) mount to M adapter question...

Also- The new 7Artisans 50/1.1 arrived, new version. It now mounts onto the M3DS, BUT the locking pin does not engage. The original one would not mount as the lens body hit the collar around the lens release button. The new one has been cut to clear it, but the shape "or something" of the locking pin keeps it from settling in place in the groove of the lens. Thickness is correct, the radius of the tip of the M3DS locking pin is different from my other Leicas. The M3DS will get the 50/1.1 Nokton for super-speed, but usually gets a Summarit or Summicron.

No issues with fit with the 7Artisans on M240, M7, M5, M4-2, M3ss. On an M3ds really tight fit and the lens release button collar scratched the body of the lens just above the base.
My impressions so far with it is it is a spectacular lens for the money. It's on my M7 right now, the only images I have with it are on digital, which is verbotten on this site. (But can be found on fredmiranda.com)

"missed it by that much" on my M3DS. I know exactly where to file. Would use a tool from a dremel, but file by hand. We're talking a fraction of a millimeter.
