Adds contrast and depth to the image while eliminating reflections. Special filter with an ultra-slim rotating mount (4.5 mm). Acts as both a UV filter and lens protection against scratches, dust, and fingerprints. Suitable for wide-angle and wide-angle zoom lenses, especially for fast AF lenses with integrated motor drive or front lens focus. No vignetting (dark corners). Innovative, extremely high-quality optical glass (only 1 mm thick). Effective from 17 mm focal length (in full-frame). Very lightweight. Multi-coated (HTMC): four coating layers are vapor-deposited on each side. Quality class (glass): Professional. Adds contrast and depth to the image, making the sky blue, clouds white, and colors clearer. Depending on the filter's position, non-metallic reflections (water, plastic, glass, etc.) are eliminated. The highest effect is achieved at an angle of 30-40° to the reflective surface.
