Many users of the old Leica R system will no doubt be glad of any opportunity to imbue new digital life into their excellent and much loved (R ) lenses. This is one such opportunity!! For technical reasons that most will appreciate this is best married to the Leica 240 camera (or later--when it comes)---with live view or using the EV to see through the lens. It is a reasonable and cheaper alternative to the Leica adapter.It may also be worth remembering that there are other adapters (metabones) available for the R lenses to match them up with the Sony mirror-less camera.
