BRIGHTLINE VIEW- AND RANGEFINDER

The camera’s brightline view and rangeﬁ nder is not only a very high-quality,

large, brilliant and bright viewﬁ nder, it is also a highly accurate rangeﬁ nder

coupled to the lens. It has a magniﬁ cation factor of 0.68x. The brightline

frames are illuminated in white by LEDs.

The brightline frames are linked to the distance setting to ensure that

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 frames, 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.

Brightline frames on a viewﬁ nder camera must be coordinated with the

angle of view of the relevant lens focal lengths. However, the nominal angles

change slightly when focusing due to the changing extension, i.e. the

distance between the optical system and the sensor plane. If the set range

is less than inﬁ nity (and the extension correspondingly greater), the actual

angle of view is smaller - the lens captures less of the subject. In addition,

the diﬀ erences in the angle of view 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 rectangular 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 distance and exposure metering, and on

ﬂ ash mode, refer to the relevant sections on pages 92/96.

Brightline frame

Actual image ﬁ eld

Set to 0.7m: The sensor detects approximately one frame width less.

Set to 2m: The sensor detects exactly the image ﬁ eld shown by the inner

edges of the brightline frame.

Set to inﬁ nity: The sensor detects approx. 1 or 4 (vertical or horizontal)

frame width(s) more.
