Black Diffusion Filter
The Black Diffusion Filter from K&F is waterproof and scratch-resistant. It creates a beautiful soft light “pastel” effect which softens skin and reduces the appearance of blemishes to create a dream-like atmosphere.
Black Diffusion Filter Features
The filter features high-end optical glass. The multi-coating reduces reflection, reduces glare and is waterproof. It has a standard transmittance 84% with black Mist 1/4 Filter.
The filter has a high build quality as the glass is optically ground and then coated with a highly crafted film layer on the surface.
The Black Diffusion Filter repels Mold and Oil, is ‘Waterproof’ and features an ‘Anti-scratch’ coating
Having hard-scratch characteristics without any impact on the quality of imaging. Water droplets or oil stains are easily removed. In the original material of optical glass, precision grinding double-sided polishing, to ensure the stability of the molecular structure.
It features an ultra-slim frame which is constructed from aviation aluminum alloy, with a depth of only 3.3mm. The ultra slim rim of the filter is designed to prevent vignetting when shooting at wider angles and zooming in with a telephoto lens.
The filter features a CNC trapezoidal design pattern on the surface of the ring-frame to ensure a large area of increased grip when the consumer is installing or removing the filter; or rotating in place while using the filter.
The filter is easy to install or remove from your camera’s lens. Simply align the threads and gently screw it clockwise onto the main thread on the lens barrel. The knurled edge gives you plenty of purchase to screw it into place. NOTE: be careful not to over tighten the filter as this may make it difficult to remove after use.
When would I use a black diffusion filter
This filter works by diffusing the light entering the lens with small aberrations; by spreading the light more evenly, a soft glow is created rather than the sharp, well-defined image when shooting without a filter. The diffusion filter creates a haze by spreading out the light across the etched filter surface. It’s entirely different from blurred or out-of-focus images — a diffused image retains its contrast and sharpness. This is the effect of bending a percentage of the image-forming light from its original path to re-focus it.
