The Leica M3 is a 35mm film camera with a rangefinder focusing system. Featuring a 0.91x viewfinder and auto changing frame lines for 50mm, 90mm, and 135mm, this camera has perhaps the most accurate focusing system throughout all Leica cameras. This camera also features the Leica M bayonet mount, which is compatible with more recent Leica M mount lenses as well as classics. It features a chromed brass body with Vulcanite grip.
