High quality protective lens filter with an aluminum alloy frame - Constructed from high quality optical glass and housed in a durable aluminum alloy frame. It enlarges the image size while preserving resolution and clarity and prevents stray light from entering the edge of the filter. - Supports film and video cameras with a fixed shutter speed range, enabling shooting in bright daylight conditions such as beaches or snowy environments on sunny days. - Multi-coated glass blocks and mitigates UV radiation, reducing haze and the blue cast that can appear in landscape photography. Protects your expensive lens from dust and scratches without compromising image quality. - Before ordering, check your camera’s lens thread size. The thread size is marked somewhere on the lens barrel or under the lens cap. The size is always indicated with the diameter symbol (O with a slash) preceding the number. Practical use scenarios - Shooting landscapes on bright sunny days at the beach or in the snow, where increased brightness requires control over glare and UV exposure. - Filming with cameras that use a fixed shutter speed range in strong daylight to maintain consistent exposure and protect the optical system. - Protecting a valuable lens from dust, scratches, and minor impacts during outdoor shoots in dusty or sandy environments while preserving image quality.
