Canon 8x20 IS Binoculars

Indicates whether a device’s battery level is being displayed or monitored, typically via an LED, screen icon, or other visual cue. A value of "Yes" means the indicator is present and active; "No" means it is absent.

The chemical composition or classification of a battery, such as alkaline, lithium‑ion, NiMH, or lead‑acid. It indicates the energy storage technology used in the product and helps users identify compatibility with devices that require specific battery chemistries.

The minimum distance at which a camera lens can focus on an object while maintaining sharpness and clarity. It is expressed as a linear measurement (e.g., meters or centimeters) and indicates how close the subject can be to the sensor before the image becomes out of focus.

The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.

The diopter compensation value indicates the adjustment in optical power (in diopters) required to correct for a user’s vision when using an optical device such as binoculars or cameras. It is expressed as a numeric value that can be positive, negative, or zero, where a positive number increases magnification and a negative number decreases it. The value represents the amount of additional lens power needed to achieve clear focus without external corrective lenses.

The exit pupil diameter is the linear size of the opening through which light exits an optical device, measured in millimetres (mm). It indicates how much light can pass through the system and affects brightness and field of view. This measurement helps users compare compatibility with lenses, filters or accessories that require a specific aperture.

The distance from the eyepiece to the eye that allows a user to see the full field of view without strain or loss of image size. It is measured in linear units such as millimetres or centimetres and applies to optical devices like binoculars, telescopes and cameras.

The maximum horizontal extent that an observer can see with an optical device when positioned 1000 metres away, expressed either as a linear measurement in metres or as an angular width in degrees. It allows comparison of how wide a telescope, binoculars or other sighting instrument can cover at that distance.

Specifies the focusing behavior of a camera or imaging device, indicating whether it uses automatic focus, manual focus, or a combination such as auto‑manual. The value is expressed as a free‑text string that describes the mode in use.

Indicates whether the product is equipped with a gyroscope sensor, which measures rotational motion and orientation. The value can be "Yes" or "No", or specify the number of axes (e.g., "6 axes"). This information helps determine if the device supports motion tracking or stabilization features.

The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

Indicates whether the device includes an image stabilization system, either optical or electronic, that reduces camera shake to produce sharper photos and smoother video recordings.

The optical magnification factor of a device such as a camera lens, binoculars or telescope. It indicates how many times larger an object appears compared to its actual size when viewed through the product. Values are expressed as a multiplier (e.g., 2x, 10x).

The linear measurement across the widest part of a telescope’s objective lens, expressed in units such as millimeters or centimeters. It indicates the size of the primary optical element and determines light‑gathering capability and image quality.

The type of electrical supply that powers the device, such as mains electricity, batteries, USB power, or a combination of these options.

The optical prism configuration used in a binocular, monocular or other optical device. It indicates whether the instrument employs a roof prism, Porro prism, BaK‑4, BK‑7, Schmidt‑Pechan or similar design, which affects image quality, size and weight.

The mass of the product expressed in a standard unit such as grams or kilograms. It represents how heavy the item is and can be used for shipping calculations, handling instructions, or consumer information.

The horizontal measurement of a product, expressed in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.
