THE EOS CONCEPT: ELECTRO-OPTICAL SYSTEMS
When
Canon introduced the EOS 650 and 620 in early 1987, this new
camera system represented a departure from the technology of the
past, with a view toward new capabilities, accuracy and precision,
and potential for system development.
While these two models were clearly designed for the amateur
market, they also gave a clear indication of future
possibilities. The new EF mount system, with its improved
strength over the FD mount and precision of electronic aperture
control was a breakthrough in lens design.
Other features such as the Evaluative metering system, A-TTL
flash, and Depth of Field AE control showed how technology could
be successfully used to make the photographer's job easier, and
actually to take better photographs.
Even with these features, though, neither camera was appropriate
for daily professional use. However, development of lenses such
as the superb EF 300mm f/2.8L and 600mm f/4.0L, and later the EF
200mm
f/1.8L, indicated that plans were under way within Canon's
development group for a future professional camera.
In early 1989, the EOS 630 gave another indication of the
direction in which Canon was heading. By upgrading its focus
tracking ability with "predictive focus, "and speeding up its motor
drive to 5 frames per second, it became a camera with features
much more attractive to the professional.
Most significant though, were the changes incorporated into the
the camera to make it work more easily in a professional
environment. Based on input from CPS members here in the United
States, and other pro users around the world, Canon's engineers
were able to provide small touches that significantly improved
performance. Particularly interesting was the Custom Function
control system that lets the photographer set up basic camera
functions for each particular kind of shooting situation.
But the EOS 630 was still not Canon's professional camera.
THE EOS-l: CANON'S PROFESSIONAL AUTOFOCUS CAMERA
The EOS-1 is the pinnacle of the design effort that began nearly
five years ago. Created especially for the demanding professional,
the EOS-1 introduces a new standard against which all other cameras
will be compared.
Innovative features that combine automatic operation with
sophisticated manual control put you in command. Designed for
improved operability and ease of use, the EOS-1 allows you to
concentrate on composition and capturing the decisive moment.
