E. Automatic Diaphragm and Return System
When Connection Plate begins to move in the direction of the arrow mark, Return Lever will
move in the same direction via MP Moving Lever. P Lever Adjuster Pin will move Preset
Lever in that direction, too, via P Connection Plate. Then Lens Side Preset will be freed, and
the lens will be set to the prescribed aperture.
The movement of Return Lever in the direction of the arrow mark will be retarded by P Brake
Lever, Wheel G and Fly Wheel, and the aperture of the auto preser lens will be stabilized.
When Last Blade closes following the operation of the shutter, Return Lever will move in the
opposite direction to the arrow mark and shift Preset Lever in the same direction via P Con-
nection Plate and P Lever Adjuster Pin. Then Lens Side Preset will be pushed back, and the
diaphragm will be opened.

tion of the shutter, SW 2 and SW 3 will be turned on, while SW 4 will be turned off.
