The H&Y K-Series ND16 + CPL 95mm Drop-In Filter is a high-quality camera accessory for professional photographers and enthusiasts. This filter combines a Neutral Density filter (ND16) with a Circular Polarizer (CPL) in a single 95mm drop-in format, reducing light transmission by 4 stops (ND16) while minimizing reflections and enhancing color saturation. Made from premium optical glass with a multi-layer nanocoating, it ensures minimal color cast, high light transmission, and resistance to scratches, water, and dust. The drop-in design allows for easy integration into compatible lens filter holders or systems, providing an efficient solution for landscape, portrait, and videography. It maintains image sharpness and contrast, supports precise exposure control, and enables creative effects under various lighting conditions. The filter features a slim frame to prevent vignetting with wide-angle lenses and comes with a protective case for storage. Its dimensions are approximately 95 mm in diameter and 3 mm in thickness, weighing around 120 g. Ideal for use in bright environments, it helps achieve slower shutter speeds or wider apertures without overexposure, while the polarizing element reduces reflections from non-metallic surfaces such as water and glass. This accessory is compatible with lenses that accept 95mm drop-in filters, enhancing versatility for outdoor and studio applications. It is important to note that a suitable filter holder or adapter is required for mounting. The product belongs to the H&Y K-Series, known for durability and optical precision, making it a reliable choice for demanding photographic tasks.
