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.

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 distance from the optical center of a lens to its image plane when the lens is set at its working focus, expressed in a standard length unit such as millimetres or centimetres. It indicates the angle of view and zoom capability of an optical system and helps users compare lenses with different fixed focal lengths.

Specifies whether the camera’s focusing system operates automatically or requires manual adjustment. Common values include "Auto", "Manual", and combinations such as "Auto/Manual".

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.

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 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.

Indicates whether the camera or lens includes optical image stabilization to reduce blur caused by camera shake. A value of Yes means the device has a built‑in stabilization system; No means it does not.

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 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.
