Origin: Soviet-era 35mm SLR, produced primarily in the 1980s by KMZ and Belomo.
Lens Mount: Uses the widely popular M42 screw mount, allowing for interchangeable lenses (often paired with a Helios lens).
Operation: A fully mechanical, manual-focus camera that requires no batteries to operate the shutter.
Metering: Features a distinct, uncoupled selenium-cell light meter (external, no batteries needed) that provides readings which the photographer must manually set on the lens and camera.
