Cokin 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 system can be used with any lens, provided they are large enough to cover it sufficiently. (Only the adapter ring may need changing).
Cokin
produce various differently-sized versions of the Creative Filter
System. The smallest is "A" ("Amateur", 67mm wide). The larger "P"
("Professional", 84mm wide) system covers cases where "A" filters are
too small to cover the lens (or would cause problems at wider angles).
The still-larger "X-Pro" filters are 130mm wide. The "A" and "P" sizes
in particular are de facto standards, with many other manufacturers producing compatible filters and holders.
