BRIGHT-LINE VIEW AND RANGE FINDER
The camera’s bright-line view and range fi nder is not only a very
high-quality, large, brilliant and bright viewfi nder, it is also a highly
accurate range fi nder coupled to the lens. It has a magnifi cation
factor of 0.68x. The bright-line frames are lit in white by LEDs.
The bright-line frames are linked to the range setting to ensure that
the parallax - the off set between the lens and the viewfi nder axis -
is automatically compensated. At a range of below 2m the sensor
detects slightly less than shown by the inner edges of the bright-
line frame, and slightly more at longer ranges (see adjacent dia-
gram). These slight variations, which are hardly ever critical in prac-
tice, are due to the operating principle.
Bright-line frames on a viewfi nder camera must be matched to the
image angle of the relevant lens focal lengths. However, the nomi-
nal image angles change slightly when focusing due to the chang-
ing extension, i.e. the distance between the optical system and the
sensor plane. If the set range is less than infi nity (and the exten-
sion correspondingly greater), the actual image angle is smaller -
the lens captures less of the subject. In addition, the diff erences in
the image angle tend to be greater at longer focal lengths, as a
result of the greater extension.
In the middle of the viewfi nder image is the square range metering
image, which is brighter than the surrounding image fi eld.
If the exposure meter is turned on, the exposure meter LEDs and
the fl ash symbol LED appear at the lower edge of the viewfi nder
image. For more details about setting the range and exposure
metering, as well as fl ash mode, refer to the relevant sections on p.

Set to 0.7m: The sensor detects approx. one frame width less.
Set to 2m: The sensor detects exactly the image fi eld shown by the inner
edges of the bright-line frame.
Set to infi nity: The sensor detects approx. 1 or 4 (vertical or horizontal)
frame width(s) more.
