## Summary description

K&F 4-in-1 camera filter kit for 77 mm lenses includes UV, circular polarizer (CPL), ND4 neutral density, and Nano-K coated optical filters. Designed to protect the lens, reduce reflections, control glare and polarize skies, and decrease exposure by 2 stops for longer shutter use. Suitable for landscape, travel, and outdoor photography.

## Long description

K&F 4-in-1 77mm camera filter kit includes UV, circular polarizer (CPL), ND4 neutral density, and Nano-K coated optical filters sized for 77 mm lenses. The set is designed to protect the front element of the lens, reduce surface reflections, control glare and enhance color saturation with the CPL, and reduce incoming light by approximately 2 stops with the ND4 to allow longer shutter speeds. Nano-K coating improves resistance to water, oil and fingerprints and helps maintain image clarity.
Advantages
The UV filter provides basic protection and reduces ultraviolet haze without affecting color balance. The circular polarizer reduces reflections from non-metallic surfaces, deepens blue skies and improves contrast in landscape scenes. The ND4 filter decreases exposure by about two stops, enabling slower shutter speeds or wider apertures in brighter conditions. All filters feature precision-threaded metal frames for secure mounting and the Nano-K coating for easier cleaning and durable optical performance.
Suitable for
Landscape photography where reflection control and sky polarization improve image quality
Travel and outdoor photography requiring lens protection and compact filtering options
Long-exposure photography in daylight using the ND4 to achieve motion blur effects
Portraits or general use when reducing glare and enhancing color contrast is needed
Key specifications
Filter diameter: 77 mm
Filter types included: UV, Circular Polarizer (CPL), ND4 (≈2 stops)
Coating: Nano-K water- and oil-resistant optical coating
Frame material: metal threaded mount for secure attachment
Effect on exposure: ND4 reduces light by approximately 2 stops; CPL selectively reduces polarized reflections
How to use
Screw the appropriate 77 mm filter onto the front of a compatible lens by aligning the threads and rotating clockwise until hand-tight. Use the UV filter as an all-purpose protective element left in place during general shooting. Rotate the CPL ring while looking through the viewfinder or live view to adjust the degree of polarization and minimize reflections. Fit the ND4 when you need to reduce exposure by roughly two stops — meter exposure with the filter in place or use exposure compensation/longer shutter speeds to achieve the desired effect. Clean filters with a soft microfiber cloth and a suitable lens-cleaning solution to maintain optical clarity.
Usage recommendations
For best results, mount filters firmly but avoid overtightening. When using the CPL, compose while adjusting the polarizer to observe changes in sky saturation and reflections. When stacking filters, be aware of potential vignetting on wide-angle lenses; use only combinations that remain clear of the image corners. Store filters in a protective case when not in use to prevent scratches and dust buildup.
