As someone who works extensively in video production, I am very familiar with diffusion filters. I've been using them for a while for various projects. What makes this filter from K&F Concept so special, in addition to the great look, is the magnetic filter system. Having recently bought a few more different magnetic filters, I quickly grew fond of this concept and have almost completely switched.

The diffusion filter does exactly what it is supposed to do, no more or less. The filter will add tons of character to your digital images from your DSLR. The magic of the filter is that it literally makes the lights (especially light sources) glow. The effect adds a dreamy halo look to the highlights, a common look of feature film styles. I've attached a screenshot of a music video I recorded with the filter.

In the box you get the diffusion filter, an adapter ring and the lens cap. All of these items are magnetic and snap directly into each other. You simply screw the adapter ring into your lens thread and then snap the diffusion filter into place within seconds. You've got the gorgeous look you've been waiting for.
