The Cokin Speed filter is good for still life and creative portraits. It has a hole in the center and the outside blurs outwards, giving an explosive movement to the photo edges. Cokin A series filters can be used on any film and digital camera, using an A series holder. The filter slots into the holder and the holder attaches to your lens using an adaptor ring. Rings are available in sizes from 36mm to 62mm.THIS ITEM HAS FREE P&P WITHIN THE UK
