USING THE RANGEFINDER
IMAGE FIELD (BRIGHT-LINE FRAME)
The bright-line rangefinder of this camera is not just a very
high-quality, large, brilliant and bright viewfinder – it also doubles
as a highly precise, lens-coupled rangefinder. All Leica M lenses
with focal lengths between 16 and 135 mm are coupled automati-
cally when they are attached to a camera. The viewfinder has a
magnification factor of 0.73x.
The bright-line frame is coupled with the focusing function in such
a way that the parallax – the offset between the lens axis and the
viewfinder axis – is compensated automatically. At ranges under 2
m, the sensor captures slightly less than indicated by the inner
edges of the bright-line frame, and slightly more at longer ranges
(see adjacent diagram). These slight, almost negligible deviations
are systemic. The bright-line frame of a camera with viewfinder
must be adapted to the view angle of the relevant focal length of
the lens. The nominal view angle changes slightly when focusing
due to the changing draw-out, i.e. the distance of the lens system
to the sensor level. When the set distance is below infinity (and the
draw-out accordingly greater), the actual view angle also decreases
– the lens captures less of the image object. The view angle
differences at greater focal lengths tend to be larger due to the
greater draw-out.

Notes
• The bright-light frames illuminated by white light LEDs appear
alongside the exposure meter LEDs at the lower edge of the
viewfinder image, once the camera electronics are activated.
• The rectangular distance measuring field, which is brighter than
the surrounding metering field, is in the center of the viewfinder
frame. Please read the relevant sections for more information
about distance and exposure metering.
