Spot-Matic
(1960)
World's first SLR featuring TTL metering and spot metering. Also, the exposure meter was
already coupled with both aperture and shutter, thus fully anticipating modern camera
meters. |

Metalica
(1960)
Built around the then new Copal Square vertical running metal blade shutter (giving the
name to the camera), it featured 27-cell non-TTL selenium meter on pentaprism and bayonet
mount. That metering system was already surpassed by the Spot-Matic concept. |
