The Fujica G690 was introduced in 1969 as an easy way to take high quality photos of Tokyo tour groups. Intended to mimic the handling of a Leica and with clear inspiration from the Combat Graphic rangefinder, the G690 combined easy flash use with interchangeable lenses and the ability to use the quick-developing sheet film that was the lifeblood of the Japanese tour industry at the time.

This lens mount would be used for a few more cameras, such as the GL690 and GM670, before being retired in favor of lighter fixed-lens models like the Fuji GW690.
