The Memo Clip on the back of the
Roll Film Holder Cover accepts the
box top of the film carton and can
also be used for other reminders.
Each film holder has this important
feature. It electronically interfaces the
film holder with the AE Prism Finder,
the focal plane shutter and the lens
diaphragm, for exposure automation.
This eliminates the need of having to
manually reset the meter, every time
you change film holders loaded with
different films. Therefore make it a
routine to always set this dial with the
speed of the loaded film.
