The classic size for low light
The 8 indicates the magnification, while 56 is the objective lens diameter in millimetres. 8x56 binoculars are a classic choice for hunting and night-time observation.
DDoptics specialises in roof-prism designs for its 8x56 binoculars, with two main types: binoculars with Abbe-König prisms and binoculars with Schmidt-Pechan prisms.
Understanding the eye, optics and light
8x56 binoculars combine eightfold magnification with a 56 mm objective lens diameter. Together, these produce a large 7 mm exit pupil – a proven combination for night hunting, high-seat observation and watching nature when little ambient light remains.
In darkness, the pupil widens to let more light into the eye. Around 7 mm is a commonly used reference for a young, dark-adapted eye – not a fixed maximum for everyone. Age, ambient light and individual differences all affect its actual diameter.
The exit pupil is the beam of light available behind the eyepiece. With a 7 mm exit pupil, 8x56 binoculars can fill a widely dilated eye pupil. If your pupil opens to only 5 mm, for example, the outer part of that beam goes unused. A larger exit pupil will not automatically make the image brighter in that situation.
The objective lens collects light from the subject. Inside, prisms turn the image the right way up, while the eyepiece presents a magnified view. With your eye at the correct distance from the eyepiece, its pupil can receive the emerging beam. The eye then focuses the light onto the retina.
To turn this theoretical light-gathering potential into a good image, coatings, prisms and glass quality must also perform well. High light transmission and low stray light support brightness and contrast. Even high-quality 8x56 binoculars need ambient light: they cannot produce a visible image in complete darkness.
Our starting point: a large exit pupil combined with a magnification that is well suited to handheld use.
The same objective diameter with greater magnification produces a smaller beam. With a sufficiently dilated eye pupil and equal light transmission, an extended scene appears darker than through 8x56 binoculars.
The same magnification with a smaller objective also reduces the exit pupil diameter. In deep twilight, 8x56 binoculars can therefore deliver more usable light to the eye.
Calculated example for an eye with a 7 mm pupil and equal light transmission: the beam's cross-sectional area is approximately 64% for 10x56 and 56% for 8x42, relative to 8x56. These are not universal figures for perceived brightness or the ability to resolve detail. With a smaller eye pupil, the brightness difference may be reduced or disappear altogether.
8x56 binoculars strike a balance between a large exit pupil, useful magnification and a steady view. That is why they are a classic choice for night hunting and late twilight. They are not automatically the best choice for every eye or situation, though: weight, steadiness, the detail you need and optical quality all matter too.
More than a large objective lens
When choosing 8x56 binoculars, size is only part of the picture. Differences in optical coatings, glass types, build quality and prism design also determine light transmission – the amount of light that actually passes through the optics.
DDoptics' higher-end 8x56 binoculars use larger, bright Abbe-König roof prisms, while more affordable binoculars often use Schmidt-Pechan image-erecting prisms, which may transmit somewhat less light depending on their coatings and design.
An 8x56 configuration produces a 7 mm exit pupil. This is approximately the diameter to which a young eye's pupil can dilate at night or in twilight, which is why 8x56 binoculars are widely regarded as an excellent choice for night-time use.
How much light the eye can use also depends on individual pupil size and ambient lighting. Optical binoculars require some remaining light.
The series in detail
The Pirschler 8x56 binoculars feature large Abbe-König prisms for optimised night-time performance. These prisms are characterised by very low light loss.
The lens elements in the Pirschler 8x56 binoculars have DDlucid coatings to reduce unwanted reflections and transmit more light for bright, natural-looking images.
The Pirschler 8x56 binoculars also have an open-bridge design for an improved grip.
The Nighteagle Ergo 8x56 binoculars use Schmidt-Pechan prisms and are designed to keep their overall size and weight as low as possible.
Despite their low weight and moderate price, these 8x56 binoculars deliver a bright, vivid image as twilight deepens.
The Ergo binoculars' lenses feature HDX-FMX coatings for strong optical performance and a natural view with faithful colours.
The current version is the Nighteagle ERGO 8×56 Gen4 shown above.
