Bolex Front

Controls on the Bolex, front:

a. run button
When this button is pushed the camera will run for as long as it is held down.

b. turret lock
The turret lock can be used to lock down the turret, and is helpful for heavy zoom lenses, but tends to get in the way at other times.

c. turret handle
This handle is used to rotate the turret. It can be folded away, as pictured here, to allow easy winding of the camera.
