Operating Instructions

Focusing/diaphragm setting
Focusing is only possible with a mirror swiveled in and, thus, the shutter cocked. For the purpose, turn the focusing
ring (23) until the object to be taken is sharp in the field lens. The depth of focus can be read on the depth of field
scale (21). Example: distance: 5 meters; aperture: 8; depth of focus 3.5 meters to about 9.5 meters. Turn the
diaphragm setting ring (20) to set to required diaphragm number opposite to the red mark. Automatic diaphragm
lenses retain full aperture when the diaphragm number is set. The diaphragm is stopped down releasing the shutter.
Press lever (19) to check the depth of focus for the set diaphragm number in the field lens. The built-in field lens can
be replaced with other suited for specific photographic fields (see operating instructions, accessories for close-ups).
