K&F CONCEPT 49MM NANO C Series-3-in-1 Multi-Function Variable ND2-32&CPL& Black Mist 1/4

The K&F Concept 49mm 3-in-1 Multi-Function Filter combines a variable ND2–ND32, CPL, and Black Mist 1/4 diffusion filter in a single compact design. Made with high-quality AGC optical glass and 28-layer nano coating, it enables smooth exposure control, reduces glare, enhances color saturation, and adds a cinematic soft glow, ideal for photography and videography in varied lighting conditions.

Elevate your photography and filmmaking with the K&F Concept 49mm Nano C Series 3-in-1 Multi-Function Filter. This hybrid filter integrates three essential tools in one compact unit:

• Variable ND2–ND32 Filter – Provides smooth exposure adjustment over 5 stops, perfect for controlling light in bright conditions, enabling long exposure effects such as motion blur, soft flowing water, or creative depth-of-field control.
• CPL Circular Polarizer – Reduces reflections and glare from water, glass, and non-metallic surfaces while improving color saturation and contrast, ideal for landscape and architectural photography.
• Black Diffusion 1/4 Filter – Softens highlights and gently lifts shadows to produce a cinematic mist effect, adding warmth and professional character to portraits and cinematic scenes.

The filter is engineered to eliminate the “black X” effect common in some variable ND filters. Constructed from premium AGC optical glass with 28 protective nano coatings, it is resistant to water, dust, oil, and scratches, ensuring high light transmission and minimal distortion. The anodized aluminum frame is CNC-milled for durability, precise lens fit, and a matte finish that prevents reflections.
