They are particularly noted for their "Creative Filter System". It was invented by photographer Jean Coquin and introduced in 1978. Based primarily around square filters, these require a holder which is attached to the lens via a simple adapter ring of the appropriate size. Unlike screw-thread circular filters, which are each tied to lenses of a specific diameter, those in the Cokin system can be used with any lens, provided they are large enough to cover it sufficiently. (Only the adapter ring may need changing). In addition, more than one filter can be used at the same time to multiply filter effects possible. High gloss oblong softcover shows almost no signs of use. Reading crease and storage indents in front cover only signs of use. Interior is tight, clean and unmarked. The brochure laid in gives examples of some scenes with and without filters. ? Size: 16mo - over 5 - 6" tall, 116pp. ? Condition: Near Fine Softcover Catalog w/ Brochure ? Always privately owned.
