The ETR Motor Drive E has been specifically designed and developed as an integral accessory
in the Zenza Bronica ETR System of Photography. lt provides the'photographer with
complete motorized film winding and shutter cocking operations, which leaves the user free
to concentrate on the subject. Furthermore, when used in combination with another
important ETR accessory, the AE Finder E, there is complete automatic exposure control,
which totally frees the photographer to concentrate on his subject and allows him total
creative control.
To get best results, please read this instruction manual carefully before using the equipment.
Thoroughly familiarize yourself with its controls and operation before loading your first roll
of f ilm, and your pleasure in using the Motor Drive E on the Zenza Bronica ETR (or ETR-C)
will even be greater.
