Congratulations on your choice of the Zenza Bronica ETRS| single lens re-
flex camera. Based on the technology and experience gained with the
ETRS, the ETRSI offers you high quality performance, handling con-
venience and the versatility required for professional photography.
TheZenza Bronica ETRS| has been developed as a "system" camera, with
a very high degree of modularity, with interchangeability in lenses, finders,
focusing screens and film backs. We have also refined our professional
features including flash synchronization at all shutter speeds up to the
fastest 1/500 second. Also, full auto-flash control, based on TTL-direct
light measurements at the film plane, with an exclusively-developed
SCA386 System Adapter. Furthermore, the Zenza Bronica ETRS| is sup-
ported by a complete range of accessories for use in day{o-day assign-
ments, as well as for special camera work.
Although the following instructions are based for convenience on a stand-
ard combination consisting of the ETRS| main camera body with the
standard Zenzanon-E ll 75mm lens, Film Back Ei 120 and Waist-Level
Finder E, the choice of lens, film back and finder is left to your discretion
and to suit your picture-taking needs. To insure the best results from your
Zenza Bronica ETRSI, may we suggest that you read this instruction
manual carefully, before you even assemble the camera and accessories.
