Focusing/Diopter Adjustment - Leica DUOVID 8+12x42 Manual De Instrucciones

Notes:
Intermediate settings are possible, although
identical magnification in both optical systems
cannot be guaranteed in this case. Furthermore,
the automatic diopter setting (ADC™ – Auto-
matic Diopter Compensation, see also the next
section "Focusing/Diopter compensation") only
applies in the two end positions. Incorrect set-
tings can therefore quickly lead to a strain on
the eyes and to fatigue.
As the left ring is linked to the automatic diopter
setting, its movement is slightly stiffer than that
of the right ring.

Focusing/Diopter adjustment

With the Leica Duovid the central focusing ring
(6) is used to set the focus for variously distant
objects.
Note:
The focusing of the Leica Duovid is retained after
the magnification is changed. However, a slight
adjustment can be required in practice. This is
especially true when changing to a higher magni-
fication after having focused with a lower magni-
fication. The reasons for this are the larger depth
of field at lower magnification, which often leads
to slightly less precise focusing, and the eyes'
accommodation capacity.
