Rollei MC UV filter

The Viltrox Pro Series Ultra Slim MC UV Protection Filter with a diameter of 49 mm offers professional lens protection with exceptional optical performance. This ultra-thin filter features multi-layer coating technology that allows for 99.5 percent light transmission while effectively blocking UV rays under 390 nm to prevent bluish color casts in photographs. Made from B270 professional optical glass, the filter maintains high surface flatness and parallelism through precision grinding processes, ensuring minimal impact on image quality. The 18-layer high transmission coating provides uniform light distribution with only 0.3 percent surface reflection, significantly reducing lens reflections and light scattering. The aluminum alloy frame is only 3.2 mm thick, making it suitable for wide-angle lenses without causing vignetting or dark corners. The matte frame effectively absorbs stray light and offers corrosion resistance and durability. Surface treatments include water-repellent and oil-resistant coatings that repel moisture and resist dirt, maintaining optical clarity under various shooting conditions. With a 96HD hardness rating, the filter provides scratch resistance and reliable protection for camera lenses in outdoor and studio photography. The precisely CNC-machined construction ensures secure attachment and consistent performance in different lighting environments while preserving color accuracy and image sharpness.
