The lens cannot be attached or detached unless the shutter is cocked and the reflex mirror
charged. Therefore, first, rotate the film winding crank to cock the lens shutter and charge
the reflex mirror action before attempting to remove the lens.
B. To detach the lens, rotate the lens in the clockwise direction while
depressing the lens release button until the lens makes a full stop, at
which point it can be detached.
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.
* Should the lens release button appear, or feel pre-activated at this
time, this will indicate that the lens attachment is not proper.
The 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.
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. The shutter is closed by shifting the time exposure lever in
the opposite direction and exposing the letter "A" once more.
A. First, cock the shutter with the film winding crank and then pull up
the time exposure lever release.
* Except for time exposures, always shift the time exposure lever so
that the letter "A" is visible on the lens barrel and keep the time expo-
sure lever release pushed in all the way.
