Canon Interchangeable Lenses FD System

The Canon F-1 has adopted the full aperture
metering system which boasts an accuracy
‘equal to, if not better than, the stopped-down
metering system employed in the Canon FT.
It incorporates a transmitting mechanism for
aperture signals in the lens and camera body.
In order to expand the F-1 system, Canon's
Optical Department, making full use of
electronic computers, developed a series of
high performance interchangeable lenses of
the highest quality. The newly designed
lenses boast high quality and preeminent
performance and are clearly classified. The
FD series of lenses also include special lenses,
In the wide-angle lens series, lenses for every:

10 degrees in angle of view were produced,
while on the telephoto side, lenses for every
100mm in focal length were provided to
greatly strengthen the photographic range.
Besides these, aspherical lenses, fluori
lenses, and fisheye lenses were developed.
Furthermore, the use of multilayer antire-
flection optical coatings and the adoption of
Canon's unique focusing mechanism have
contributed to the strengthening of the series,
of FD lenses. This new group of lenses can be
used not only for the Canon Fl, FTb, TLb
but also for the Canon FT, Pellix and models
with R lenses.
