The bright-line measuring viewfinder
The bright-line measuring viewfinder of the
LEICA M4-P has been designed to combine
the functions of a coupled rangefinder and
of a viewfinder of outstanding quality.
Whatever you see within the bright frame
will appear on your exposed film. The
bright-line frame is coupled with the range-
finder so that the parallax - the difference
between the lens axis and the viewfinder
axis - is automatically compensated.
The measuring field, brighter than the
surrounding field, is located in the centre of
the viewfinder field. All the lenses of
21-135mm focal length are coupled with the
rangefinder on insertion in the LEICA.
When lenses of 28 (from serial No.
2314921), 35, 50, 75, 90 and 135 mm focal
length are inserted, the appropriate bright-
line frames will automatically appear in the
viewfinder image in the combinations 28 +
90mm, 35 + 135mm, and 50 + 75mm.
