Cosina's compact film SLR — the C1 with basic features at minimum cost.
The Cosina C1 is a compact 35mm film SLR from Cosina, a Japanese manufacturer that produced cameras under both the Cosina brand and as OEM for many other labels. The C1 is a basic automatic exposure SLR with manual override capability.
The Cosina C1 provides standard SLR operation with aperture-priority automatic exposure, a proprietary or Pentax K-compatible mount depending on version, through-the-lens metering, and 35mm film transport. The specific mount version determines lens compatibility.
Cosina produced the C1 in multiple configurations for different markets — some versions used Pentax K mount, making them compatible with a wide range of K-mount lenses. Verify the specific mount from physical inspection.
Identify the mount type from the lens coupling. Test shutter and AE operation. Check film transport mechanism. Verify metering accuracy.
