Jerome had reported he had some focus issues with his Cokin filter, especially when zoomed in with the stocklens where the image stayed blurred and the camera could not focus right. He also showed me some shots, not zoomed in, where I noticed focus shifts in the same frame, the image was sharp on the right side but not in the center.
According to Jerome the filter does produce some colorshifts but much worse, some serious focus issues, just check below video and see for yourself.
