Time (T) Exposure; Exchanging Lenses - Zenza Bronica ETRS User Manual

12. Time (T) Exposure

Time exposures are made with the time exposure lever on the lens, regardless of the setting
on the shutter speed scale. However, the lever is locked to prevent accidental movement
and must be unlocked for use.

13. Exchanging Lenses

The lens cannot be attached or detached unless the shutter is cocked.
Therefore, first, rotate the film-winding crank and cock the lens shutter.
A. Unscrew the set screw on the time exposure lever until further rev-
olution is not possible, which will permit the lever to be moved freely.
* Except for time exposures, always shift the time exposure lever so
that "A" is visible on the lens barrel and keep it locked with the
setscrew to prevent accidental movement.
B. Next, cock the shutter with the film-winding crank and then shift
the time exposure lever to the left (looking from the body towards
the lens), which will expose a red-colored "T" on the barrel. The shut-
ter will stay open when the shutter release button is depressed in this
condition. Shifting the time exposure lever in the opposite direction
and exposing the letter "A" once more closes the shutter.
A. To attach the lens to the main body, align the red dots on the lens
and the main body and then insert the lens fully into its mount.
Rotate in the counter-clockwise direction until it stops, with an audi-
ble click, which will indicate that it is securely locked.
B. To detach the lens while sliding the lens release button backwards,
rotate the lens in the clockwise direction until it makes a full stop, at
which point it can be detached.
