Bronica ETR-Si Instruction Manual

30

One of the greatest attractions of the ETRSi is complete film back interchangeability which
makes it possible to detach or attach the film back at any time, in daylight and/or in mid-
roll, and use different film types interchangeably. Thus, an extra film back or two will let a
single ETRSi do the work of several, such as, for example:

1.Take color and black-and-white shots of the same subject.
2.Reload without losing a shot, even when shooting fast action, by using preloaded 
film backs.
3.Use different film speeds in the same session, by changing film backs.
4.Use a single ETRSi in common, but with personal film backs, in the studio or at 
home.
5.Use of 35mm films broadens the choice of film widely. In addition to the standard 
35mm format, a new panoramic 24 X 54mm wide format is also available.
6.Use Polaroid® pack film back E for instant pictures for previewing lighting and/or 
exposures.
