Seeing both lenses a few questions arise inmediately:
Who is the manufacturer?
I´m sure none of them was designed in Leica M Mount, so probably the RF couldn´t be operated, am I right?
If yours, do you have some test pictures?
This pictures show me that something I´ve been thinking for some time is possible at the extent of loosing the RF, it is to use M42 lenses with an adapter to Contax / Kiev mount.
