Fixing Mirror Upwards
In case the Canon Lens FL 19mm F 3.5 is used,
the mirror should be fixed upwards . For mount·
ing 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 fixed-up position.
• Attach the lens quickly in the shade. The
film will sometimes become foggy if the lens
is
left unattached.
• When the mirror is locked, combined usage
of the separate viewfinder for this lens becomes
necessary.

Do not use the mirror lock for ordinary photog ·
raphy w ith the automatic aperture. When its
use becomes necessary, however, release the
pre· set aperture 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 be-
ing burned.
• After the mirror lock device has been used,
be sure
to return the mirror lock lever com-
pletely to its original position . Failure to do
this will result in inexact focusing .
