Created by renowned French fashion and landscape photographer Jean Coquin in 1978, the Cokin Creative Filter System remains a staple of the international photography community. The system is based primarily on square or rectangular “drop-in” filters that slide into a filter holder. The holder mounts on lenses via a simple adapter ring of the appropriate size.
Most all Cokin filters are made from very high-quality, European produced optical resin know as C39. Jean Coquin chose this resin because of its optical clarity and stability. It is light and unbreakable, has an extremely high optical transmission factor and is perfectly suited for tinting. It is the perfect base for making photographic filters, its precision surpassing that of mineral glass.
