[Leica] IMGS: Animals

[Frank Filippone]

There are at least 3 issues with lens mount adapters
1) flange register. Distance from mount to film plane. Looking this up on Wiki, the SL mount has a register of 20mm. Sony E mount (A7 etc family) has a register of 18mm. From these numbers, an adapter could work
2 & 3) Electrical and mechanical interface for iris control and AF capability.   Zero compatibility.   All setting must be done on the lens.   No AF. 
On older lenses, this can be manually coordinated. But since SL lenses have no on-lens aperture control, whatever the lens does at rest is what you must use it at. F2.8?  F16?
Some of these issues have been overcome in other cameras (Hassy lenses fully coordinated with the Leica S bodies or Canon lenses on Sony bodies) but it is rare. 

The bottom line is that it is possible to put SL lenses on another body, but don’t hold your breath. 

Maybe Leica will make a 50mp SL2?
