Podrobný popis

The K&F CONCEPT 58mm Nano-D Series Variable ND2–32 Filter with CPL is a multifunctional 2-in-1 lens accessory designed for exposure control and reflection reduction. Combining a variable neutral density filter and circular polarizer, it allows precise light adjustment, enhanced color contrast, and glare reduction in a single compact, high-quality optical glass filter.

The K&F CONCEPT 58mm Nano-D Series Variable ND2–32 CPL Filter is a versatile all-in-one optical solution designed for photographers and videographers who need both exposure control and reflection management in a single filter. Built with a combination of variable neutral density (ND) and circular polarizing (CPL) functionality, it provides enhanced creative control over lighting conditions, contrast, and reflections.

The ND2–32 range allows smooth light reduction equivalent to approximately 1–5 stops, enabling users to control shutter speed and aperture for cinematic motion blur or balanced exposure in bright environments. At the same time, the CPL function helps eliminate unwanted reflections from non-metallic surfaces such as water and glass while enhancing color saturation and contrast for more vibrant images.

Constructed from imported AGC optical glass with 24-layer multi-coating, the filter ensures high light transmission, waterproof protection, and resistance to scratches while maintaining sharp image quality and minimizing color shift. The advanced coating also helps reduce flare and ghosting in challenging lighting conditions.

A self-locking variable frame design enables smooth, infinite rotation between ND levels while preventing the “X” cross effect commonly seen in variable ND filters. The integrated pusher-style adjustment mechanism makes it easy to fine-tune exposure settings, especially useful for video shooting where real-time adjustments are required.

Designed for 58mm threaded lenses, this filter is compact, durable, and travel-friendly, making it ideal for landscape, portrait, travel, and video production use.
