Canon RF 28-70mm F2 L USM

Indicates whether the device has an automatic focusing capability that adjusts the lens or sensor to achieve sharp images without manual intervention.

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 colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

Specifies the type of device or system that the product is intended to be used with, such as a PC, server, notebook, surveillance system, or other electronic equipment. The value represents a single category and can be used to filter or group products by their target platform.

The linear measurement across a circular or round object, taken through its center. It is expressed in units of length such as millimeters, centimeters, inches, or feet and represents the widest span of the item.

The minimum and maximum focal lengths that a camera lens or optical system can cover, expressed in millimetres (mm). It indicates the zoom capability of the device and helps users understand the field‑of‑view range available.

The linear dimension of a product measured in a standard unit such as meters, centimeters or inches. It represents the overall size along one axis and is used to compare physical dimensions across similar items.

List of lens mount interfaces supported by a camera or lens, such as Canon EF, Nikon F, Sony E‑mount, Micro Four Thirds, etc. The value can be a single interface name or a comma‑separated list of multiple compatible mounts.

The aspect ratio describes the proportional relationship between the width and height of a lens’s image circle or sensor coverage, expressed as a simple fraction (e.g., 12/9). It indicates how wide or tall the captured image will be relative to its other dimension. This value helps users compare lenses for compatibility with camera sensors and desired framing.

The classification of a camera lens, indicating its optical design and intended use such as prime, zoom, wide‑angle, telephoto, macro or specialty types (e.g., fisheye, polarizing). It helps buyers understand the lens’s focal range, aperture characteristics, and typical shooting scenarios.

The highest f‑number (aperture value) that a camera lens can achieve when fully wide open. It indicates the maximum light‑gathering capability of the lens and is expressed as an integer or decimal without units.

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

The total count of openings, such as holes or ports, present in a product. This value indicates how many separate apertures are available for access, ventilation, or connection purposes.

The total count of individual diaphragm blades included in the product. It indicates how many separate blades are present, which can affect performance characteristics such as airflow or pressure control.

A set of predefined camera settings that automatically adjust exposure, white balance, focus and other parameters to suit specific shooting situations such as portrait, landscape, night or sports. Each value represents a selectable mode that the user can choose from when capturing images.

Indicates the types of products, users or environments for which the item is intended or compatible. The value can be a single category such as "Gaming" or a specific product type like "Computer case".

The classification of an ultrasonic motor used in a product, such as brushed, brushless, DC, AC, or specific pole configurations. It indicates the electrical and mechanical design that determines performance characteristics like torque, efficiency, and noise level.

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.

Indicates whether the product supports any form of optical or digital zoom, allowing the image or field of view to be magnified beyond its native resolution.
