Adapted Blotar f2. 58 mm carl zelss lens

[Chris…]

I found this lens at a garage sale. Will this work on a canon R7 with an adapter?

Firstly. No comment of adapters.

The markings on the lens indicate a possible manufactured date 1950-1960.

It needs some careful cleaning. No comment on whether the internals will function.

YMMV - good luck!

Isn't that the original Zeiss lens that the Soviet Helios 44 was copied from? The one with the swirly bokeh?

I have a Helios 44-2, in M42 mount with an M42 to EF adapter and the EF to RF adapter. It works fine. A but milky when wide open, but stopped down to 2.8 it cleans it up.
