Speed Booster for NEX bodies and Leica R lenses, uncomplete compatibility list ...

My Summicron R 1:2 35 mm could not fit in the Speed Booster.

There is a part in the Leica mount to protect the rear glass.

David (Leitax) wrote to me that I could file it a bit and sent me the link to do it.


I did that and now it works !

I have to find the right way for a Vario-Elmar-R 4,0/35-70mm ROM.

I guess I have the same problem; how much did you have to file?
