Instruction Manual

B. All Bronica interchangeable lenses for the ETRSi have fully auto-

matic lens diaphragm which means that the focusing screen is always

viewed at the full aperture, with the brightest possible image.

However, depressing the depth of field preview lever will stop the

lens diaphragm down to the pre-selected lens opening (aperture),

permitting the photographer to check the depth of field effect on the

focusing screen.

* The aperture ring must not be adjusted while the depth of field pre-

view lever is being depressed.

* Furthermore, the depth of field preview lever must not be used for

taking an exposure reading, with the AE-III Finder E, in both automatic

and manual exposure operations, the indicated shutter speed setting

will not be correct. This is because the Bronica ETRSi has been

designed for full aperture metering and over-exposure will result, in

this case.

15. Waist-Level Finder and Interchanging Magnifiers (con’t)

D. The standard magnifier supplied with the waist-level finder has a

power of -1.5 diopters, which can be exchanged for others with pow-

ers o f -4.5, -3.5, -2.5, -0.5, +0.5 and +1.5 diopters. These optional

accessories should be purchased to suit the user's eyesight, if neces-

sary. Simply rotate the magnifier frame in the counter-clockwise

direction to unscrew. Attach in the reverse manner.

16. Setting the Aperture

A. The aperture ring is rotated, in either direction, to set the required

f/number opposite the white index dot. The aperture ring click-stops

at the numbered settings. Intermediate settings are also possible.

* Intermediate settings can be used with PE series lenses when the

finders with built-in exposure meter are used.
