CanonEX is the first and last SLR camera Canon with gateohm built into the lens (central gateOhm-diaphragm Copal-X). The work order was designed for the production of about 20 thousand cameras.

Production was discontinued six months later due to unreliable design. gatenode and a large number of returns. Cameras of this model can be found under other names.
I came across three cameras - Porst Auto-Reflex, Mamiya Auto-Lux 35 in one of the variations and Canonex. Cameras differ from each other only cosmetically. Perhaps they were sold in different locations. At the expense of the main manufacturer - the debate continues to this day.

One thing is known - Canonex was actually produced at Canon factories.
Basic modes of operation - shutter priority... The mirror in the apparatus simultaneously served as a shutter, tightly closing the hole in front of the film, protecting the photographic material from light.
