K&F 82mm Filter Kit 4-in-1: UV Nano-K + CPL Polarizer + Lens Cap + Case (MPN SB7930)

K&F 82mm Filter Kit 4-in-1 combines two essential optical filters with protective accessories for lenses that accept 82mm threads. The kit includes a UV Nano-K filter to reduce ultraviolet haze and protect the front element of the lens, and a circular polarizer (CPL) to control reflections and increase color saturation. A matching lens cap and a protective case are included to keep the filters safe when not in use, making the set suitable for photographers who need glare control and basic lens protection in outdoor and travel situations.

Advantages

The UV Nano-K filter provides continuous front-element protection while reducing ultraviolet-induced haze, which can improve clarity in bright outdoor scenes. The CPL polarizer cuts reflected light from non-metallic surfaces such as water and glass, enhancing sky contrast and color saturation without altering exposure significantly when used correctly. Included accessories—a snap-on lens cap and a padded case—help prevent scratches and dust on the filter surfaces during transport and storage.

Suitable for

• Landscape photography requiring improved sky contrast and reduced atmospheric haze
• Outdoor and travel photography where lens protection and quick glare control are needed
• Architectural and product photography to manage reflections from glass and polished surfaces
• General-purpose use on any camera lens with an 82mm filter thread

Key specifications

• Filter thread size: 82 mm
• Filter types included: UV Nano-coated filter and circular polarizing (CPL) filter
• Optical treatment: nano coating on UV filter for scratch and water resistance
• Mechanical design: slim profile to reduce vignetting on wide-angle lenses
• Accessories: snap-on lens cap and protective padded case for storage and transport

How to use

Screw the UV Nano-K filter onto the lens thread when you want continuous front-element protection; it can remain mounted during general shooting to guard against dust, scratches, and minor impacts. Attach the CPL by screwing it onto the lens (or onto the UV filter if stacked) and rotate the outer ring while viewing the scene through the viewfinder or on the camera screen until reflections are reduced and colors appear more saturated. Be aware that the CPL can require small exposure adjustments—use the camera’s meter or manual settings to compensate if necessary. When not in use, store filters in the provided protective case and keep the lens cap in place to protect the filter surface.

Usage recommendations

For best results with the CPL filter, use it at a 90-degree angle to the sun to maximize polarization effects on the sky and reflections. On wide-angle lenses, check for vignetting when stacking filters; if vignetting occurs, use the UV filter alone or remove the UV before mounting the CPL. Clean filters with a microfiber cloth and appropriate optical cleaner to maintain image quality.
