Filter Kit K&F 82mm CPL ND8 ND64 magnetic 82 mm with magnetic lens cap

The K&F 82mm CPL ND8 ND64 magnetic filter kit provides a compact, magnetic solution for controlling reflections, color saturation and exposure on lenses with an 82 mm filter thread. The kit contains a circular polarizer (CPL) and two neutral density filters (ND8 and ND64) designed to be mounted and stacked quickly using the magnetic mounting system and the included magnetic lens cap. The CPL reduces surface reflections and improves color contrast, while the ND8 and ND64 progressively reduce incoming light to allow longer shutter speeds or wider apertures in bright conditions.

Advantages

The magnetic design enables fast attachment and removal without repeated screwing, and allows precise rotation of the CPL for polarization control. The set covers common exposure control needs with two ND strengths, giving flexibility for daylight long-exposure photography or when using shallow depth of field in strong light. The included magnetic lens cap protects the filter stack when not in use and acts as a simple carrying solution between shoots.

Suitable for

• Landscape photography requiring reflection control and long exposures
• Architectural and exterior shoots where window and water glare reduction is needed
• Portraits or outdoor scenes where wider apertures are used in bright light
• Video work that benefits from consistent shutter settings using ND filtration

Key specifications

• Filter thread diameter: 82 mm
• Filter types included: circular polarizer (CPL), neutral density ND8, neutral density ND64
• Mounting system: magnetic attachment and stacking
• Material: optical multi-coated glass elements within metal or composite frames
• Function: polarization control, light reduction for extended exposure control

How to use

Attach the magnetic filter directly to a lens with an 82 mm thread by aligning the magnetic ring and letting it snap into place. Rotate the CPL element to adjust the amount of polarization until reflections and color saturation reach the desired level. Stack the ND filters as required by simply placing them onto the magnetic mounting surface; start with ND8 for moderate light reduction and use ND64 for stronger reduction when longer exposures or wider apertures are needed. When finished, place the magnetic lens cap over the stack to protect the filters.

Usage recommendations

For best results, clean lens and filter surfaces before attaching the magnetic filters to avoid trapping dust. When using the CPL together with ND filters, set exposure and focus first, then fine-tune polarization by rotating the CPL. Use a tripod for long-exposure shots with ND64 to ensure sharp images.
