The diaphragm
The diaphragm is set by rotation of the diaphragm ring (his 20) on lens mount. The diaphragm numeral required for
the exposure has to be brought to meet the red index mark. Lenses with automatic spring diaphragm allow for full
aperture focusing. Not until the shutter is released, does the diaphragm close down to the preset aperture. To check the
depth of field during focusing, you simply depress lever (19) on the lens mount. This causes the diaphragm to close
down to the value preselected by means of setting ring (20).
