Foreword

Dear Customer,
Worldwide, the name Leica stands for superb
optical quality, close-tolerance precision
engineering, absolute reliability, and long product life.
We wish you a great deal of enjoyment and
success with your new Leica Duovid. The outstanding optical properties and the variable
magnification allow you to adjust these handy
binoculars to various viewing situations.
So that you can use them properly, we recommend that you first of all read these instructions.

Nomenclature

1. Eyepiece cups
Position a: unscrewed for viewing without
glasses
Position b: screwed in for viewing
with glasses
2. Adjustable rings for selecting the magnification with indexed markings
3. Fixed rings with markings for the two magnifications
4. Lockable diopter adjustment ring
5. Eyelets for carrying strap
6. Central focusing ring
7. Hinged joint for adjusting the eyebase

Warning notice
As with all binoculars, avoid looking directly
at sources of bright light with your Leica
Duovid as this could cause eye damage.

Possible applications

The Leica Duovid is a high-performance set of
binoculars with two magnifications that can be
selected as required. The lower magnification
provides a bright, stable image with a large field
of view and a large depth of field. The higher
magnification offers outstanding recognition of
details of distant objects and in conditions of
poor light. The balanced weight distribution and
the perfect ergonomics combine to give an
extraordinarily stable image despite the high
magnification.
The Leica Duovid has a hermetically sealed, nitrogen-filled, and die-cast aluminum housing.
It is therefore suited for rough outdoor use. There
is no need to be concerned with moisture as it is
100% waterproof to a depth of 5 m and the internal optical system is not subject to fogging.

Attaching the carrying strap

Attaching the protective eyepiece cover

The eyepiece cover is placed over the eyepiece
cups. It is fixed using the carrying strap.

Care and maintenance

Your Leica binoculars need no special maintenance. Use a soft lens brush or a blower to remove large particles of dirt, sand, etc. To remove
fingerprints etc., first wipe the eyepiece and lens
with a damp cloth, then dry them with a piece of
clean, soft chamois leather or lint-free cloth. If
the binoculars, particularly the telescopic eyepieces tubes, are very dirty, rinse them in a basin
of water rather than under a running faucet.
Always rinse off salt water.
Moisture inside the central focusing unit (visible
through the scale window) will dry quickest when
the diopter adjustment ring (4) is pulled up, i. e.
unlocked.

Tripod Adapter

This practical tripod adapter is equipped with a
1
/4” thread for all Duovid models and allows
long-term shake-free viewing. In the case of the
Leica Duovid 10+15×50 it is included in the
scope of delivery.

Carrying case

The soft leather carrying case supplied with your
Leica binoculars protects them from dirt. A flap
with snap fasteners is provided at the top of the
case, through which the carrying case strap can
be fed.

Adjusting the eyecups

The eyepiece cups (1) can be easily adjusted by
turning them and they lock securely into the
selected positions. They can also be completely
removed for thorough cleaning.
For viewing with eyeglasses (Figure A) they
remain in the fully screwed-in position. For
viewing without eyeglasses, they are unscrewed
by turning them anticlockwise. Two positions are
available for optimum adjustment (Figure B, C).
If the eyepieces are very dirty, it is recommended
to remove the cups for cleaning (Figure D). To
do this, they are turned slightly back clockwise
and gently pulled while in the fully unscrewed
position.

Adjusting the eyebase

To set the eyebase, adjust the binoculars at the
hinged joint. The left and right fields of view
must merge and produce a single circular image.

Setting the magnification

The Leica Duovid offers the user a choice of two
magnifications. The magnification is adjusted
using the adjustable rings (2) below the two
eyepiece cups. Both rings must always be completely moved into the appropriate end position.

Notes:

Intermediate settings are possible, although
identical magnification in both optical systems
cannot be guaranteed in this case. Furthermore,
the automatic diopter setting (ADC™ – Automatic Diopter Compensation, see also the next
section “Focusing/Diopter compensation”) only
applies in the two end positions. Incorrect settings 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 magnification after having focused with a lower magnification. 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.


Leica Duovid

Compensation for individual defective vision for
viewing without eyeglasses is made using the
diopter ring (4), which is normally locked.(Figure
A). First of all, the central focusing ring is used to
focus the right barrel on an object. The diopter
ring is then released by pulling it up. (Figure B).

Attention:

If the left magnification adjustment ring is not in
an end position, i. e. at 8x or 12x/10x or 15x, the
diopter ring is locked and cannot be released.
The diopter ring is then twisted to set the optimum focusing for the left barrel. Pressing the
diopter ring back down locks the set value.
Defective vision differences of up to ±3 diopters
can be compensated in this way.


Leica Duovid

Attention:
Do not adjust the magnification with the diopter
ring released. The left ring for adjusting the
magnification is locked when the diopter ring is
released.
For viewing on just the left or the right side, the
other eye should be kept closed or the appropriate half of the binoculars simply covered at
the front on the lens.
The set value can be conveniently read from the
accurate scale on the diopter ring.
