THE BRIGHT-LINE VIEW AND RANGE FINDER
This camera’s bright-line view and range finder is not only a very
high-quality, large, brilliant and bright viewfinder, it is also a highly
accurate range finder coupled to the lens. All lenses with focal
lengths from 16 to 135mm connect automatically when fitted on
the camera. The viewfinder has a magnification factor of 0.68x.
When using lenses with focal lengths of 28 (Elmarit from serial
number 2 411 001), 35, 50, 75, 90, and 135mm, the relevant
LED-lit frame is automatically illuminated in the combinations
28+90mm, 35+135mm, and 50+75mm - in a choice of red or
white. This enables it to be seen perfectly in all lighting conditions
and for all subjects.
Selecting the bright-line frame color
1. In the main camera menu, (see p. 154/248) select
Frameline Color
(page 3,
SETUP
section), and
2. select the desired color in the sub-menu.
The size of the bright-line frame corresponds to a sensor size of
23.9 x 35.8mm at a range setting of 2m. It is linked to the range
setting to ensure that the parallax - the offset between the lens and
the viewfinder 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 diagram). These slight variations, which are hardly
ever critical in practice, are due to the operating principle.
