HOWTO USE BINOCULARS
Thisis the proper way to adjust a
binocular for outdoor use.
1. Lookthrough the binocular, and adjust
the spread ofthe eyepieces
untilyou see one circular image.
2. Close your righteye and look through
the lefteyepiece. Use the focusing ring
to focussharply on the subject.
3. Close your lefteye and look through the
righteyepiece. Do not turn the center
Designed specificallyfor the 18x50 IS AWand
the 15x50 ISAW binocular, these eyepieces
preventcondensation and fogging. Useful in
warm, humid and cold weather.

right-side eyepiece diopter ring as
necessary.
4. The binocular should now be adjusted
for your eyesight. When you move the
focusing ring for differentdistances,
the image willremain sharply focused.
Please note thateye spacing and diopter
adjustmentis different for each person.
Another person would have to adjustthe eye
spacing and diopter again.
For eyeglasswearers
Ifyou look through the binocular while
wearing eyeglasses, your eyeswillbe further
awayfrom the eyepieces, causing the image
to graduallyshade off at the edges. To
preventthis, use the foldaway rubber
eyepiece ringsif available.
Foradded comfort, eyeglass wearerscan adjust the
eyecupson IS series binocularsby folding back the
rubbereyepiece ringsor by twisting the eyepiece up or
down in the case of the 10x42L IS WP.

testwith a building or other flat subject
with pronounced horizontalor vertical
linesby observing whether lines near the
peripheryremain sharp or tend to curve.
Canon’soutstanding optics, including

linear distortion.
Remembering the readingsof the diopterswill make it
easierto readjust the binoculars after someone else
hasused them.

Curvature ofthe field

High qualitybinoculars show excellent
sharpnessnot only at the center of
images, butat the edges as well. This is
easyto check: stand at a 90˚ angle to a
wallwith detail and focus. Then check
the sharpnessfrom center to edge. For
the bestpossible flat-field performance,
mostCanon binoculars use Field
Flattener and Asphericallenses.

Clarity

To checkfor clarity, pointthe binocular at
a clearlydefined edge, like the lettering
on a sign or a constellation in the night
sky. Imagesshould appear crisp and
razor-sharp.
