HOW TO USE BINOCULARS
This is the proper way to adjust a
binocular for outdoor use.
1.
Look through the binocular, and adjust
the spread of the eyepieces
until you see one circular image.
2.
Close your right eye and look through
the left eyepiece. Use the focusing ring
to focus sharply on the subject.
3.
Close your left eye and look through the
right eyepiece. Do not turn the center
Designed specifically for the 18x50 IS AW and
the 15x50 IS AW binocular, these eyepieces
prevent condensation and fogging. Useful in
warm, humid and cold weather.

focus ring any further. Turn only the
right-side eyepiece diopter ring as
necessary.
4.
The binocular should now be adjusted
for your eyesight. When you move the
focusing ring for different distances,
the image will remain sharply focused.
Please note that eye spacing and diopter
adjustment is different for each person.
Another person would have to adjust the eye
spacing and diopter again.
For eyeglass wearers
If you look through the binocular while
wearing eyeglasses, your eyes will be further
away from the eyepieces, causing the image
to gradually shade off at the edges. To
prevent this, use the foldaway rubber
eyepiece rings if available.
For added comfort, eyeglass wearers can adjust the
eyecups on IS series binoculars by folding back the
rubber eyepiece rings or by twisting the eyepiece up or
down in the case of the 10x42L IS WP.

through the binocular and second, that
there’s no secondary “band” of color(s)
at the edges of the object. This is
important because at higher
magnifications, chromatic aberrations
tend to occur more frequently. Canon
binoculars correct for this problem by
using UD lenses from Canon’s EF Lens
series (highest magnification models)
or Super Spectra Multi Coating.
they appear to the naked eye. It’s easy to
test with a building or other flat subject
with pronounced horizontal or vertical
lines by observing whether lines near the
periphery remain sharp or tend to curve.
Canon’s outstanding optics, including
Aspherical lens elements, correct for
linear distortion.
Remembering the readings of the diopters will make it
easier to readjust the binoculars after someone else
has used them.

Curvature of the field
High quality binoculars show excellent
sharpness not only at the center of
images, but at the edges as well. This is
easy to check: stand at a 90˚ angle to a
wall with detail and focus. Then check
the sharpness from center to edge. For
the best possible flat-field performance,
most Canon binoculars use Field
Flattener and Aspherical lenses.
Clarity
To check for clarity, point the binocular at
a clearly defined edge, like the lettering
on a sign or a constellation in the night
sky. Images should appear crisp and
razor-sharp.
Parallel Lines
Excellent binoculars will render parallel
lines in a subject as perfectly straight as
