Brings contrast and depth to the image while eliminating reflections. Special filter with an ultra-flat rotating mount (4.5 mm). Serves as both a UV filter and a lens protector against scratches, dust, and fingerprints. Suitable for wide-angle and wide-angle zoom lenses, especially for fast autofocus lenses with integrated motor drive or front lens focus. No vignetting effect (dark corners of the image). Made from new, extremely high-quality optical glass (only 1 mm thick). Effective from a focal length of 17 mm (at 35 mm). Very lightweight. Multi-coated (HTMC): four coating layers are vapor-deposited on each side. Quality class (glass): professional. Image effect: enhances contrast and depth, makes the sky appear blue, clouds white, and colors clearer. Depending on the position of the filter, non-metallic reflections (water, plastic, glass, etc.) are eliminated. The highest effect is achieved at an angle of 30-40° to the reflecting surface.
