The Minolta Riva Zoom 90c is an 35mm auto focus zoom camera made by Minolta. It is also known as the Minolta Freedom Zoom 90c and may have been used as the basis for the Leica C2-Zoom. Camera is notable for the Auto Standby Zoom (ASZ) system which Minolta claimed could automatically set zoom based on subject distance. This system included the Eye Start (hence ES) moniker on camera where a sensor would detect and activate when held to the eye. As typical of the era had DX coding and flash with a red eye reduction mode.

Was sold with optional IR control in some retail boxes
