Backs
The F-1's back was removable. A Data Back F (for the original F-1 and F-1n) or Data Back FN (for the New F-1) (which being mechanical is now incapable of putting the current year on a photo) or a bulk film back that could hold 250 exposures could be attached. The Film Chamber 250 could be used alone or with the Motor Drive Unit or Motor Drive MF (the MF's grip had to be removed and coupled via a dedicated cord).

Famous quotes containing the word backs:
“The trouble about soldiers in Mr. Siegfried Sassoons poetry ... is that they are the kind of people who in a railroad train have to travel with their backs to the engine. Peace can have but few corners softly padded enough for such sensitives.”
—Rebecca West (18921983)
“Those who work their minds rule; those who work with their backs are ruled.”
—Chinese proverb.
Mencius.
