Sanei Sangyo, made in 1956, rangefinder camera. Lens: C. EZUMAR ANASTIGMAT 50mm F3.5 I used this camera for several years, but I'm selling it to organize my belongings. The shutter speeds change accordingly. You can see the double image in the rangefinder. However, I haven't measured it accurately. The lens has age-related dirt and minor scratches, so I recommend it to those who can enjoy the charm of an old camera. It's a compact camera, measuring 8.5cm x 10.5cm x 7cm.
