Cokin Filters:

Advantages of square filter systems

Cokin filters were invented by professional photographer Jean Coquin, and are now the world's leading range of special effect filters suitable for SLR, video, medium and large format camera systems.

By using square filters, which fit into a holder and are attached to a lens via an adapter ring, the photographer has a number of immediate advantages:

• there is no need to duplicate filters to fit different size lenses
• up to three filters can be used at once to create unique effects
• the photographer has control over the positioning of the effect on the photograph

Here's how the system works:

1. Screw the adapter ring onto your lens.
2. 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.
3. 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.

A-series can be used with lenses whose filter ring is up to 62mm;   recommended for focal lengths over 35mm.

P-series fit larger diameter lenses, up to 77mm For shorter focal lengths 20-24 or 28mm as well as for wide-angle zooms (24-50mm, 28-85mm, 35-135mm) System P is strongly recommended. It is available in diameters ranging from 48 to 82mm and eliminates vignetting (dark edges).

X-Pro Series has been specially developed for professionals using medium or large format cameras and the 'extreme' lenses used by broadcasters, videographers and photographers. It is available in diameters ranging from 62mm to 112 mm , and will fit lenses with diameters up to 118mm with the Universal Adapter Ring.
