Canon Kwanon Camera
Canon was founded on September 2, 1934 in a garage to make an inexpensive copy of the
horribly expensive new LEICA. The idea was to make the same camera, but at a price people actually could afford.
The Kwanon used a NIKKOR lens. Garage-shop Canon made no lenses, and since Nikon made no cameras, Canon simply had Nikon make lenses for them.
The Kwanon prototype came out 80 years ago, and production started in 1936.
These "Kwanon" cameras became very popular because they worked about as well as a real LEICA, and they cost much, much less. As always, Canon expanded the limits of technology and made cameras far more advanced than LEICA. For instance, Canon rangefinder cameras of the late 1950s and newer had life-sized viewfinders, something LEICA has never been able to do, and the Canon viewfinders changed their magnifications to match the lens used, something else LEICA has never been able to do.

No official correct pronunciation exists, as both seem as logical.
EF is an acronym for "Electro-Focus". The EF lens mount permits all Canon EF lenses ever produced to be mounted on any
Canon EOS camera manfactured by Canon Inc. Different from the the FD mount, EF's breech-lock ancestor, the EF mount employs a bayonet-style mount. EF
lens auto focusing is controlled by a dedicated electric motor
configured in the lens. The interaction between the camera and lens
occurs through electrical contacts without benefit of plungers or
An offshoot of the EF mounting system, Canon added the EF-S lens support, in 2003, designed only for EOS digital cameras featuring a 1.6x crop produced after 2003. Any other Canon EOS camera that features an EF mount only will not permit mounting of EF-S lenses.
