Product Overview
Extremely satisfactory photography, with a compact design emphasizing great handling
ease. Creative picture-taking can not take place, even when the powers of expression
are rich if there are too many limitations placed on the photographer. In the
case of the ETR-Si however, special importance has been placed on this point and
there is a high degree of system flexibility. Not only has a compact and light-weight
camera been developed, based on Bronica's exclusive lens shutter system, but Bronica
has advanced the use of electronics in various sophisticated functions, resulting
in enhanced precision. And, the pursuit of greater holding stability has also
lead to an improvement in handling ease. Furthermore, the very flexible "system"
design of the ETR-Si, in which lenses, finders, film backs and focusing screens
can be freely exchanged, as well as full range of valuable accessories makes it
possible to customize the "system" to match the user's intention in
picture-taking. These versatile functions in a very compact camera have been successful
in greatly increasing the creative freedom in photography.
