The minimum and maximum f‑number (aperture value) that a camera lens or optical system can achieve, expressed as a numeric range (e.g., "F1.4-F16") or a single value when only one aperture is available. It indicates the zoom and light‑gathering capability of the lens.

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 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).

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 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 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 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.
