IF: Individual focusing binoculars
For individual focusing binoculars,
diopter adjustment is basically
unnecessary.
CD Focus right and left eyes separately.
® When the subject changes, focus with
both eyes separately.
Note: For zoom binoculars
When viewing the subject at
a different magnification, first
correctly adjust focusing at a higher
magnification. This minimizes
blurring, which may occur when you
change magnification.
* If you change the magnification from
low to high after adjusting focusing
at
low magnification, serious image
blurring may occur.
