Focusing / Diopter adjustment
With the Leica Ultravid binoculars the central
focusing ring (4) is used to set the focus for
variously distant objects.
Compensation for individual defective vision
for viewing without eyeglasses is made using
the diopter ring (4), which is normally locked
(Figure A). To unlock the two rings the diopter
ring is pulled up (Figure B). Now, the central
focusing ring only effects the focus of the left
optical system, the diopter ring only that of
the right system. Using one of the rings, then focus the respec-
tive barrel on the desired subject. Continue
by setting the optimal focus for the second
barrel with the other ring. Pressing the diop-
ter ring back down locks the set value. The
set value can be conveniently read from the
accurate scale on the diopter ring.
