Canon FT - Fixing Mirror Upwards for Specific Lenses

Fixing Mirror Upwards
In case the Canon Lens FL 19mm F 3.5 is used, the
mirror should be fi xed upwards . For mounting the lens,
turn the mirror lock lever in the direction of the arrow.
The mirror is thus fixed to a position under the focusing
screen. The lens is then attached and used with the
mirror in the f ixed· up posi tion .
• Attach the lens quickly in the shade. The film will
sometimes become foggy if the lens is l eft unatta ched.
• When the mirror is locked, combined usage of the
separate viewfinder for th is lens becomes necessary.
Do
not use the mirror lock for ordinary photography with
the automatic aperture . When its use becomes necessary,
however,
release the pre·set ap e rture and take the pictures
under" manual" conditions.
• When the mirror is locked, always keep the lens
covered when not in use. If it is turned in the direction
of the sun without the cap , there is the danger of the
shutter curtain being burned.
• After the mirror lock device has been used, be sure
to return the mirror lock lever completely to its orig inal
position. Failure to do this will result in inexact focusing .
