Objective lens diameter

This number affects the objective lens surface area

through which light enters the binocular. The larger the

objective lens, the more light that is able to get into the

binocular. Your image will be brighter at dusk, at night or

in other low light conditions. With an 8x44 binocular the

objective lens diameter is 44 millimeters - in contrast to

the usually available 42 millimeter sizes your STEINER

XP binocular will offer a 10% larger objective lens surface.

Field of view

The size of a binocular's field of view is stated in feet or as

an angle and uses the value of reference at 1,000 yards. If

your binoculars offer you a field of view of 390, then you

will be able to see a 390 feet wide image at the distance

of 1,000 yards.

After years of research our engineers have created a new

level of perfection with our XP Technology: enjoy your
new STEINER XP binoculars. In contrast to other binocu-
lars, XP Technology enabled STEINER to achieve higher
light transmission over the entire visible wavelength 

range. A difference you will instantly see in all conditions.

However, several factors determine the optical perfor-

mance of a binocular. They perform to the maximum only

when all these parameters are optimally calibrated and in

harmony with each other.

Magnification

The value indicates how much closer an object appears

through the binocular. The higher the magnification, the

closer the object appears. However, similar to a photogra-

phic zoom lens, a higher magnification narrows the field

of view. With an 8x44 binocular, objects will appear to be

eight times closer than with your naked eyes.

Cleaning

Clean your binoculars by wi-

ping the rubber armoring with

a damp cloth. More stubborn

dirt may require a light soap

and water solution on a damp

cloth. The Nano Protection

Optics of your XP binoculars
repels dirt or water to form on

the lenses – simply wipe the

objective or ocular lenses

gently with the cleaning cloth

that came in the original box.

Clean the lenses only when

necessary and never use any

acrid cleaning solutions.

Formula for Exit pupil:

Exit pupil

Look through your binoculars and then move it about 12

inches away from your eyes. You will see a bright circle

within the oculars. This dictates how much light gets to

your eye. The exit pupil is measured in millimeters (mm)

and is a crucial indicator for low-light performance of a 

binocular. A human pupil can open up to 6 mm in low

light and accordingly, binoculars that are used in low-light

c o n d i t i o n s

should offer a

large exit pupil.

Storage

When not using your STEINER XP binoculars you should
store them in a cool dry spot. Avoid storage in spaces ex-

posed to direct sunlight (i.e. in a car) or with extreme

temperature changes.
