Promaster

Accurate Colour Balance: By diffusing incoming light, the lens cap averages the colour temperature of a scene, allowing your camera’s manual white balance function to capture precise and natural hues.

Dual Functionality: Serving as both a protective lens cap and a white balance tool, it safeguards your lens from dust and scratches while being readily available for quick white balance adjustments.

Durable Construction: Crafted from robust plastic with a neutral tone, the cap ensures longevity and consistent performance across various shooting environments.

Easy to Use: The cap consists of two parts: a filter mount and a detachable cap. Simply attach it to your lens, set your camera to manual focus, aim at your subject, and activate the custom white balance function to achieve optimal results.
