Canon FT QL - Lens Mount (FL and R Series Lenses)

■ Canon FL lenses let you see the actual sharpness
through the viewfinder by turning the manual aperture
ring or the A-M ring.
■ Although air bubbles may sometimes be seen in a lens,
they do not affect the resolution power or the sharpness
of the picture.
Lens fyiount (FL and R Series Lenses)
All Canon FL lenses which have the FL mounts can be used
with the Canon FT, except the FLP 38mm F 2.8.
■ It is also possible to attach and use all the R lenses
for Canonflex use. However, as the pre-set aperture
mechanism differs, pictures must be taken by controlling
the aperture manually.
