K&F filter set Nano-D 3-in-1 UV, CPL, ND1000 for 49mm lenses with 2 lens caps and 2 cases

The K&F filter set Nano-D 3-in-1 for 49mm lenses contains three screw-in photographic filters: a UV filter, a circular polarizer (CPL) and an ND1000 neutral density filter. Each filter is sized for 49mm thread mount and uses K&F Nano-D multi-coating to reduce reflections and preserve color fidelity. The set is delivered with two lens caps and two protective cases for secure transport and storage.

Advantages

The UV filter reduces ultraviolet haze and protects the front element from dust and scratches without affecting exposure. The CPL filter controls reflections and glare from non-metallic surfaces and improves color saturation and contrast in skies and foliage. The ND1000 filter provides a 10-stop exposure reduction, enabling long-exposure effects such as motion blur in water and cloud movement under bright conditions. Nano-D coatings help minimize flare and ghosting while maintaining sharpness.

Suitable for

• Landscape photography to enhance sky contrast and reduce haze
• Architectural and outdoor scenes where reflections need control
• Long-exposure photography of waterfalls, rivers or clouds using ND1000
• Everyday lens protection against dust and minor impacts

Key specifications

• Filter thread diameter: 49 mm
• Filter types included: UV, circular polarizer (CPL), ND1000 (10-stop)
• Optical coating: multi-layer Nano-D anti-reflective coating
• Construction: slim screw-in metal frame designed to reduce vignetting on wide-angle lenses
• Accessories: two front lens caps and two protective cases for storage and transport

How to use

Screw the appropriate filter onto the lens front thread securely but without over-tightening. Use the UV filter as a permanent protective layer; it requires no exposure adjustment. Rotate the circular polarizer while observing through the viewfinder or on the camera LCD to find the desired reduction of reflections and increased saturation; meter and adjust exposure as polarizers typically reduce light transmission. Attach the ND1000 when long exposures are needed; use a tripod and remote release or camera timer, and set exposure either through long exposure mode or by calculating the exposure compensation for a 10-stop reduction. Store unused filters in their protective cases to avoid scratches and dust.

Usage recommendations

When using the CPL or ND1000 filters, check your camera’s meter and histogram and consider using manual mode or exposure compensation to achieve correct exposure. For wide-angle lenses, use the slim-frame filters to reduce the risk of vignetting. Clean filters with a soft lens cloth and a suitable cleaner before use to maintain image quality.
