Canon 577 G - Manual (Page 37)

Wide Adapter 577G-20
This accessory performs the same
function as Wide Adapter 577G-24
except it makes it possible to use the
577G with lenses down to 20mm in
focal length. It should be attached in
the same way as Wide Adapter
577G-24 and also has color-coded
distance ranges on its side which re­
place those on the flash. In all other
respects, the flash may be used as
usual. With this accessory, the
577G’s guide number becomes 24 at
ASA 100.
Sensor Unit G100
This accessory assures correct ex­
posure measurement when the flash
is detached and used up to about
one meter away from the camera. It
may be attached in the same way as
Sensor Unit G20.
Flash Coupler F
This accessory is specially designed
for mounting the 577G’s sensor on a
Canon F-1 camera. Further details
may be found in its individual in­
structions.
Adapter for Motor Drive MF
With this accessory, the bracket may
be mounted on the base of a Canon
Motor Drive MF. Screw it into the
socket on the side of the camera
support section of the bracket as il­
lustrated. The pin should be inserted
into the socket on the side of the
motor drive. Position the motor drive
properly on the support before final­
ly tightening the attachment screw.
Tele Adapter 577G
This screen is for using the 577G
with a lens having a focal length of
100mm or more. Simply slide it over
the flashhead in the same way as the
Wide Adapter 577G-24 so that the
colored distance ranges on its side
can be seen from the back of the
camera.
