The Seven5 Holderhas been specifically designed for today’s Compact System Cameras, including both fixed and interchangeable lens cameras. First you screw an adaptor ring (not included) to the lens and then snap-on the holder and insert your filters.
This holder comes with two filter slots enabling a broad range of creative options and precise exposure control. For instance you could control the skies exposure with a Neutral Density Grad and then add a Big Stopper for interesting long exposure effects.
Simply slide one or two filters into the holder and position precisely where you need them. Crucially the holder can also be rotated to any angle, enabling the light to be controlled no matter where it's falling in the frame. A Polarizer can also be clipped on and independently rotated, leaving the filter slots unaffected.
