Cokin H270A Full ND Filter Kit

The Cokin H270A Full ND Filter Kit consists of three Neutral Density plain filters and is designed to reduce the amount of light reaching the sensor, without affecting the colour balance. ND filters are generally used when using a long speed to capture smooth motion (EG waterfalls) and cut the amount of light entering the lens (by 1,2 or 3 stops) so you can get an all-around, well exposed image. ...

How the Cokin System works

The Cokin Creative Filter System consists of three main components: A filter holder / Adapter ring and a Filter.

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.
