Leica 21mm SA on a Bessa R4?

[erik]

I just want to be sure-- will the Leica 21mm SA f4 work with full metering on the Bessa R4?

No- the rear element of the SA protrudes too deep.

Don't try. You might get your 21SA rear element scratched by the shutter blade.

wow, worse than I thought. Thanks for the info!
