Brings contrast and depth to the image and removes reflections. This special filter features an ultra-flat rotating mount (4.5 mm) and serves as both a UV filter and lens protection against scratches, dust, and fingerprints. It is suitable for wide-angle and wide-angle zoom lenses, especially for fast autofocus lenses with integrated motor drive or front lens focus. There is no vignetting (dark corners of the image) with this filter. It is made from new, extremely high-quality optical glass that is only 1 mm thick and is effective from a 17 mm focal length (at 35 mm). The filter is very lightweight and multi-coated (HTMC) with four coating layers vapor-deposited on each side. It is classified as professional quality glass. This filter enhances contrast and depth, making the sky appear blue, clouds white, and colors clearer. Depending on the filter's position, non-metallic reflections (such as from water, plastic, or glass) are eliminated, with the highest effect achieved at a shooting angle of 30-40° to the reflecting surface.
