Distance Metering/Focusing; Superimposed Image Method (Double Image); Split Image Method - Leica MP Manual

Distance metering/focusing

Due to its large effective metering basis, the
rangefinder on the LEICA MP is very precise. The
benefits of this are particularly noticeable when
using wide-angle lenses with their relative steep
depth of field.

The 0.85x viewfinder's higher magnification with its longer base
width results in a further increase in focusing accuracy.
The rangefinder metering field is visible as a
bright, sharply defined rectangle in the center of
the viewfinder. If you keep the large viewfinder
window (8) closed, only the activated bright-line
frames and this metering field remain visible. The
focus can be set using either the superimposed
image or split image method:

Superimposed image method (double image)

In a portrait, for example, aim the rangefinder me-
tering field at the eye and turn the distance setting
ring on the lens until the contours in the metering
field merge. Then choose your subject trimming.

Split image method

When taking photographs of architecture, for
example, aim the rangefinder metering field at a
vertical edge or another clearly defined vertical
line and turn the distance setting ring on the lens
until the contours of the edge or line can be seen
at the limits of the metering field with no misalign-
ment. Then choose your subject trimming.
In practice, there is often no clear distinction be-
tween the two methods. Both methods can be
used very effectively in combination.
