Is it possible to mount via adapters a Leica R super angulon (R mount) 21 mm f/3.4 on a Sony NEX 5n or 7? I have this lens and an R to M adapter. Was wondering if it would fit using a second adapter (NEX E to Leica M). I've read some reports about the rear lens element sticking out and not fitting in the camera. I was planning on buying a Sony NEX and wanted to see if I could use this lens. I'd appreciate any input.

Thanks!
