The 82mm K&F Concept Nano-X Magnetic CPL Filter comes with a magnetic adapter ring and a magnetic lens cap in a compact storage case. The 82mm adapter ring screws onto lenses that have 82mm front filter threads. The CPL filter then magnetically attaches to the adapter ring and is just as easily removed when you want to swap in a different magnetic filter from K&F. The lens cap can be magnetically attached to the CPL filter when you're done shooting. The lens cap is also threaded for direct attachment to lenses.
The CPL filter eliminates reflections from non-metallic surfaces such as bodies of water and glass windows. Example uses include shooting through car windshields and capturing lakes. The filter also makes blue skies bluer by eliminating reflections from the sky, as reflected light often shows up as a whitish glare. The filter features glass optics with 28 layers of coating. The multicoating ensures optimal image quality and protects from water, oil, and scratches. The aluminum frame of the filter is ultra-slim and has a knurled exterior so you can better grip it with your fingers.
