For many years it 'has been the desire of camera fans for telep hoto
lenses with increased optical performance and maneuverability and
more compactness , However these features were not realized due to
limitations in design and manufacturing techniques,
The Canon telephoto lenses were designed in combination with the F 1
system With the intensive use of an electronic computer the antici ·
pated aims were achieved. Also, by separating into the lens section
and the focusing unit , it is now easy to change the focal lengths by just
interchanging the lenses. In addition to improved optical performance ,
maneuverability and compactness , the group of Canon telephoto lenses
were
greatly up· graded with portability and economy in mind .
Telephoto lenses, which are indispensable for photograph ying those
subjects which the camera cannot close up on, are very eff e ct iv e in a
wide range of fields such as shooting sporting ev ents , news photog -
raphy and recording wild life.

Features of FL 400mm, 600mm and 800mm Lenses
1 Optical performances were greatly increased with the help of an
electronic computer
2. Photography can be immediately performed by simply connecting
the lens and the foc using unit.
3. The telephoto ratios were made as small as possible so that the
overall sizes of the lenses would be small.
4. With the focusing unit as the base, focal lengths can be easily
changed by just int erchanging the lenses.
5. The automatic aperture mechanism , with which stopped-down
metering can be performed , was adopted .
6. The
rack and pinion system was adopted so that focusing can be
smoothly performed even when the camera is heavy with various
attachments (Motor Drive Unit, Film Chamber etc.) It is designed for
safety and reli ability .
7 When the focal length changes by interchanging lenses, the aper -
ture scale indication automatically changes with the manipulation of
the focal length shifting ring.
8. An ordinary and compact 48mm filter can be used by inserting it
into the lens barrel.
9. Hoods, indispensable for telephotography , have been built in (FL
600mm F 5.6, FL 800mm F8)
10 . Due to the compactly designed telephoto lenses, on lyon tripod
is necessary .
11 A
neck strap has been attached to the focusing unit for con-
venient portability . Of course , this neck strap is suff i cient for also
holdin g the lens and the camera.
