Cokin Filters - the original square filter system.

Only few years ago, photographers and videographers were asking for special effect filters. Today, they ask for COKIN filters.

A French professional photographer, Jean Coquin, invented the concept of creative filter photography. To allow everybody to get a chance to produce great "creative images" Jean Coquin designed a system with the following prerequisites: simplicity, rapidity of use and versatility to leave plenty of room for individual inspiration and creativity.

What size filters should I use?There are 4 different sizes of filters to choose from: A series / P series / Z-Pro professional series / X-Pro professional series. Plus Cokin have developed a new range of Magnefix conversion lenses for use on digital cameras, mobile telephones etc. and a range of Digital SLR kits. Full details on each of the ranges can be found on the left hand menu of this page.
What are Cokin filters made from?
CR-39 Organic Glass: All Cokin filters are manufactured from CR-39 organic glass - originally launched for the vision lens industry, CR-39 organic glass boasts several major features:
Extra lightweight
Highly resistant to shocks, meaning that photographers, videographers and cameramen can handle the filters in complete confidence and safety
Excellent optical transmission and high compatibility to colouring, making Cokin filters the proven choice of photographers worldwide.
How the Cokin System works
The Cokin Creative Filter System consists of three main components: A filter holder / Adapter ring and a Filter.
Screw the adapter ring onto your lens.
Slide the filter holder on the adapter ring until it snaps in place. The filter holder is now solidly attached to the lens, yet it can rotate both left and right.
Slide the filter into one of the filter holder slots. The one closest to the filter holder housing is the narrowest; it allows the use of round filters with notched edges (polarizer, star filters..). The two central slots are intended for square filters. The outer slot can be used either for an additional filter or for a coupling ring.
