I use the Cokin system almost exclusively for Grauverlauffilter. In addition, I still have a circular polar filter. Everything is operated on a Canon 5D with different lenses, it does look good. It is not under 24mm focal length without vignetting - except the 24mm TSE does look good - as long as the lens in the initial position is. In addition to the filters Cokin a filter adapter (pickup) and an adapter ring for each Objetivgröße to be used is required.
