In its normal position, the setting wheel turns readily, but without altering the eyepiece setting. When the wheel is pulled out, you feel distinct click stops as you turn it.

Focusing with the universal screen

The LEICA R7 includes a universal focusing screen as standard feature. This produces a bright, high-contrast image and is suitable for photography in most of the situations that are normally encountered. When the image is out of focus, the edges and lines of the subject are discontinuous in the upper and lower semicircles of the split-image focusing screen (i.e. the smaller circle).

A ring formed by a screen of rectangular microprisms surrounds the central split wedge. When the image is out of focus, this screen appears to flicker. The outer circumference of this ring also marks the outline of the field

for selective exposure metering.
