Camera filter set K&F SB7482 — 4-in-1 Nano-K UV, CPL, ND4, 67 mm

The K&F SB7482 — 4-in-1 Nano-K UV, CPL, ND4, 67 mm is a compact camera filter set for lenses with a 67 mm thread. This kit combines a Nano-K UV filter for basic lens protection and reduction of ultraviolet haze, a circular polarizer (CPL) to manage reflections and saturate skies, and an ND4 neutral density filter that reduces exposure by approximately 2 stops to allow longer shutter speeds or wider apertures. The filters are constructed for everyday use in landscape, outdoor and portrait photography where control of light and surface reflections is required.

Advantages

The Nano-K multi-coating improves light transmission and helps resist water, oil and fingerprints for easier cleaning and more reliable optical performance. The circular polarizer enables polarization control without affecting autofocus or metering on modern cameras. The ND4 filter provides predictable exposure reduction useful for motion blur and depth-of-field control. The set’s 67 mm threading ensures compatibility with lenses that accept this ring size, making it simple to attach and remove filters during fieldwork.

Suitable for

• Landscape photography – reducing glare and deepening sky tones
• Outdoor and travel photography – lens protection and reflection control
• Portraits in bright conditions – enabling wider apertures for shallower depth of field
• Long-exposure effects – ND4 for moderate exposure reduction to smooth water or convey motion

Key specifications

• Filter type: UV (nano-coated), Circular Polarizer (CPL), Neutral Density (ND4)
• Thread size: 67 mm
• ND strength: approximately 2 stops (ND4)
• Coating: multi-coated Nano-K for improved transmission and surface resistance
• Mount: screw-in metal or aluminum frame compatible with 67 mm lens threads

How to use

Screw the selected filter gently onto the lens front using the 67 mm thread until snug; avoid overtightening. Use the UV filter as a permanent protector to guard the front element from dust, scratches and UV haze. Rotate the CPL filter while observing the viewfinder or LCD to adjust the degree of polarization until reflections and sky contrast meet your preference. Attach the ND4 filter when you need to reduce exposure by about 2 stops for longer shutter speeds or wider apertures; combine with tripod use for stable long exposures. Remove or swap filters as lighting and creative needs change.

Usage recommendations

To maintain optical performance, clean filters with a soft microfiber cloth and a suitable lens cleaner; store filters in their case when not in use to avoid scratches. When stacking filters, be aware of potential vignetting on wide-angle lenses and check exposure and autofocus performance after adding multiple elements.
