## Summary description

K&F 4-in-1 filter set with 46mm thread (model SB7486) includes Nano-K UV, circular polarizer (CPL) and ND4 neutral density filters. Designed for 46 mm camera lenses, the set provides UV protection, glare and reflections reduction, control of polarization and one-stop light reduction. Suitable for photography and outdoor shooting to improve image clarity and exposure control.

## Long description

The K&F 46mm 4-in-1 Filter Set Nano-K UV CPL ND4 is a compact accessory package designed for camera lenses with a 46 mm filter thread. The set combines a Nano-K UV filter for protection and haze reduction, a circular polarizer (CPL) for controlling reflections and enhancing color saturation, and an ND4 neutral density filter that reduces incoming light by two-thirds of a stop equivalence to allow wider apertures or slower shutter speeds. These filters are intended to improve image clarity, manage exposure in bright conditions and offer basic optical protection for the lens front element.
Advantages
The Nano-K UV element reduces ultraviolet haze and provides a clear protective layer without altering color balance. The circular polarizer decreases reflections from non-metallic surfaces, increases contrast in skies and foliage, and helps control glare in outdoor scenes. The ND4 filter lowers light transmission to enable greater creative control of depth of field and motion blur under brighter light. The set’s 46 mm sizing ensures compatibility with lenses that accept 46 mm threads, offering a small and lightweight solution for travel and everyday photography.
Suitable for
Landscape photography to deepen sky contrast and reduce atmospheric haze
Outdoor portraits where glare control and color saturation are needed
Street and travel photography requiring a compact protective filter
Long exposure attempts in moderate daylight using ND4 to slow shutter speed
Key specifications
Filter thread diameter: 46 mm
Includes three filter types: UV (Nano-K), circular polarizer (CPL), and ND4 neutral density
Coating: Nano multi-coating for improved light transmission and reduced reflections
Material: optical glass elements with metal alloy frame
ND4 light reduction: approximately 2 stops (0.6 OD)
How to use
Screw the selected 46 mm filter onto the front of a lens with a matching thread until secure; avoid over-tightening. Use the UV filter as a permanent protective layer and to reduce high-altitude or seaside haze. Rotate the CPL filter while observing through the viewfinder or on-screen preview to find the desired level of reflection suppression and color enhancement; the CPL must be oriented and adjusted for the effect to work. Attach the ND4 filter when you need to reduce exposure for wider apertures or slower shutter speeds; check exposure settings and use a tripod if long exposures are required.
Usage recommendations
Store filters in a padded pouch when not in use to prevent scratches. Clean optical surfaces with a blower, soft brush and microfiber cloth, using a small amount of lens cleaning fluid if necessary. When stacking filters, be aware of potential vignetting on wide-angle lenses and test combinations before critical shooting.
