Helios Vision 5.2 20x40X100 Scope

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.

A colour is a visual attribute that describes the hue or shade of an object or surface. It can be a single dominant colour, a combination of colours, or a range such as "Black, White". The value may be expressed in common names (e.g., Black, Silver) or descriptive terms (e.g., One Colour, Assorted).

Indica si un dispositivo electrónico cuenta con una brújula digital, es decir, un sensor que determina la orientación respecto al norte magnético y muestra esa información en pantalla o a través de indicadores visuales. El valor puede ser "Sí" cuando la función está presente y "No" cuando no lo tiene.

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 field of view at a distance of 1000 metres indicates the maximum horizontal angle or linear extent that an observer can see with an optical device when positioned 1000 metres away. It is expressed in degrees or as a linear measurement (e.g., metres) and allows comparison of how wide a telescope, binoculars or other sighting instrument can cover at that distance.

The linear measurement across the widest part of a camera lens, expressed in units such as millimetres (mm), centimetres (cm) or inches (in). It represents the overall width of the lens and is useful for determining fit with lenses, mounts, and accessories.

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.

Indicates whether a product can be securely attached to a tripod using the standard mounting interface. The value is typically "Yes" or "No", and may also include a measurement such as "1/4‑inch” or “3/8‑inch” to specify the size of the mounting screw required.

Indicates whether the product is resistant to water or moisture exposure. A value of "Yes" means the item can withstand contact with water under specified conditions, while "No" indicates it is not water‑resistant.
