What I mean by L mount lenses is next: This is copy from Voigtlaender web site, precisely from:

I bold part which write about L mount lenses. And that is part which confuses me.
Thanks for answers.
Richard, thank you, I thought the same, but I have no experience with Voigtlaender and wanted to check before buying.

Hi Haris !
If my memory serves me right, there is one adapter specifically designed to fit 21 to 28 mm lenses. So there are 4 of them. I think the difference is in the rangefinder coupling amplitude.
Georges, thank you, I initially tought there is one adapder for all 6 lenses, and only when saw your post I saw there is one adapter per combination of lenses, so there are three (four if you are right about 21 to 28 lenses).
The only difference between L39 to Leica M adapters is the way in which they make frames pop up in a Leica M viewfinder. If like me you have a Voigtländer T camera, you can use any adapter with any lens. I know the earlier Voigtländer R series cameras had manually-selected viewfinder frames, maybe they all do - if so, any adapter will do. The choice of adapter has no effect on rangefinder operation.
Thanks David, I will get Bessa R2A (or R3A) and as I can see viewfinder frames are manually selected.
The "L" mount is what Cosina ( Voigtlander) is calling their lenses with the Leica Thread Mount.
