The Cosina Voigtlander 21/4 is a rangefinder coupled lens that comes with an auxiliary viewfinder. It is relatively inexpensive and will work on both screw mount and M-mount leicas with the M-adapter. It is a pretty sharp lens. CV also makes a 15mm lens that is not coupled that has a very good reputation.

My current knowledge of these cameras lead me to believe that there are not many or any that are coupled and adjust for parallax in the 15 -21mm (or even 24mm) range.

Am I terribly wrong or am I stuck with a bessa l?
