Also the depth of definition can be read from the focusing ring. To the left and right of the red indicator are
diaphragm numerals. The distance figures standing against the diaphragm numeral required for the exposure show
the range of definition.
For example:
For a distance setting of five meters (16 feet 8 inches) and a f8 aperture that depth of definition reaches from
approximately 3.5 meters to 10 meters (11 feet 8 inches to 33 feet 4 inches).
When using the sports finder you may either determine the sharpness on the ground glass beforehand or adjust the
focusing scale on the lens mount to the distance estimated or measured.
The rangefinder lens
The two part images in the rangefinder lens are moved towards or away from each other by rotation of the focusing
ring (20). If the outlines join precisely where the two sections meet, the image is in correct focus. This can be
observed best on straight vertical lines.
Exchanging field lenses
Remove the finder element from the camera and then loosen the screws on the three remaining springs with a
screwdriver. Swing the springs aside, take out the spring ring and tip out the lens. Fixing any one of the other field
lenses is performed in reverse order. The thinner part of the lens must lie towards the back of the camera.
Setting the diaphragm
Turn diaphragm setting ring (17) is to bring the diaphragm numeral required for the exposure against the red mark.
Lenses with automatic spring diaphragm and automatic pressure diaphragm allow for full aperture focusing. On
release of the shutter the diaphragm closes to the pre-set aperture.
The shutter
The focal plane shutter gives exposure speeds ranging from one second to 1/1,000 of a second and "B" (any desired
length of time). For exposure speeds longer than 1 second it is advisable to use a special wire release with locking
device.
The speeds are graduated so that each figure indicates double or one half of the speed marked by the next figure on
the scale. The diaphragm scale works in a similar manner. If the light value is to be maintained, the next smaller
aperture has to be employed for twice the exposure time, or vice versa.
Setting the shutter speeds
Rotate speed setting disk (11) in either direction, before after the shutter has been cocked, to bring the desired
exposure speed against the red triangular mark.
