The rangefinder lens
The rangefinder lens forms two-part images. These are moved towards or away from each other by rotation of
focusing ring (22). If the outlines join precisely where the two sections meet, the images is in correct focus. This can
be observed best on straight vertical lines.
The focal plane shutter
The focal-plane shutter of the Pentacon Six gives exposure speeds ranging from one second to 1/1,000 of a second
and B (any desired length of time). For exposure times longer than one second 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 analogously. If the light value is to be maintained
the next more aperture has to be employed for twice the exposure time, or vice versa.
