Catalogue information
The Canon EF is an SLR camera that can be used to photograph both manually and with automatic exposure control (time priority). Canon Camera Co., Japan introduced it to press and public in 1973 as a simpler and electronic version of Canon's top-of-the-line, the Canon 'F-1'. But because almost all controls of the EF correspond to the Canon FTb - sometimes in a different place or of a different shape - the Canon EF was therefore seen by many as an improved and electronic version of the 'FTb'. The only real differences between the 'EF' and the 'FTb' are the types of shutters - a mechanical horizontal shutter, 1 to 1/1000 sec. in the FTb and a mechanical vertical travel shutter in the 'EF', also 1 to 1/1000 sec., but with extra long electronic delay times from 2 to 30 sec.
