The Pax M2 was the second in the Pax series of compact fixed-lens 35 mm rangefinder cameras made by Yamato in the 1950s. The main difference from the previous model is to the shutter, which is now cocked automatically by advancing the film. The film advance knob is also improved. The name is engraved on top of the rangefinder housing, together with the serial number. 'Pax' is impressed in the leatherette of the back.
