The 77mm K&F Concept Nano-X Magnetic Black Mist Filter 1/4 comes with a magnetic adapter ring and a magnetic lens cap in a compact storage case. The 77mm adapter ring screws onto lenses that have 77mm front filter threads. The black diffusion 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 diffusion filter when you're done shooting. The lens cap is also threaded for direct attachment to lenses.

The black diffusion filter softens wrinkles, blemishes, and other facial characteristics that are easily picked up by a digital camera. The result is a more film-like, dreamy image with less contrast. The 1/4 filter has a transmittance rate of 84% without a negative impact on image quality. The filter features glass optics with 28 layers of coating that ensure optimal image quality and protect from water, oil, and scratches. The aluminum frame of the filter is ultraslim and has a knurled exterior so you can better grip it with your fingers.
