Removes reflections and increases color saturation without altering the overall color balance, delivering more vivid images with natural tones. Key materials and construction - Rings and adapters: brass for durability and smooth threading - Rigid telephoto lens hoods: aluminum - Rubber lens hoods: special rubber compound - Matte black anodized brass filter rims: minimize reflections and prevent binding when used with other metals Optical performance - Filter factor: 2.3–2.8 (approx +1.3 stops) - Uses high quality optical glass from the Schott Group for brilliant color reproduction, strong contrast, and sharpness - Each filter side features a hard coating to reduce stray light, maintain high contrast, and prevent flare Applications and scenarios - Landscape and outdoor photography: enhances color saturation while preserving natural skies and textures - Portraits and travel photography: improves color fidelity and contrast without changing skin tones - Telephoto or backlit scenes: controls reflections and flare for clearer, more true-to-life results Notes - Designed to minimize reflections and binding when used with other metal components thanks to the matte black anodized brass rims - Built to maintain color balance while delivering richer, more defined imagery
