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:
“Good speech need not be behind other’s backs; speech behind other’s backs is not good.”
—Chinese proverb.
“Men’s hearts are cold. They are indifferent. Not all the coal that is dug warms the world. It remains indifferent to the lives of those who risk their life and health down in the blackness of the earth; who crawl through dark, choking crevices with only a bit of lamp on their caps to light their silent way; whose backs are bent with toil, whose very bones ache, whose happiness is sleep, and whose peace is death.”
—Mother Jones (1830–1930)
