The Profoto Grid and Filter Holder is the most versatile accessory for the Profoto Zoom Reflector. This grid holder accepts Profoto grids only. Its unique size aperture makes it incompatible with any other manufacturer's grids.
There is an air space between the filter and the reflector which prevents your gel filter from scorching.
Besides a Filter-Cassette, there is a diffusion filter included.
Other filters can be mounted between the light source and this accessory.
