The Voigtlander Bessa-R3M Rangefinder Camera is a modified version of the Bessa R3A camera. While being identical in all other aspects to the R3A model, the R3M features a mechanical shutter release. This makes it possible to use the camera even without batteries, albeit without metering.
The Voigtlander Bessa R3A/M is an improved version of the Bessa R2 rangefinder camera, which in itself is an advancement over the original Bessa R camera. All of the original Bessa R's outstanding features are retained; an exceptionally bright viewfinder, quiet shutter & simple LED metering system.
In addition, the Bessa R3A/M series is the first M mount camera ever to feature a 1:1 viewfinder. As a result, shooting with both eyes open is now possible. Also, when bundled with a 50mm lens, the frame lines will show a bigger area in the viewfinder.
