Cokin Filter System
Cokin creative Filter system consists of a range of colors and functionality which are held into place in front of the lens by a holder attached to a threaded adapter ring.
The holder allows the user to slide various filters into place and even stack filters together. This holder is then attached to the lens via a threaded ring with a diameter to match the filter thread of the lens.
The major benefit of cokin filter system is that the holder, along with the collection of filters can be attached to different lenses by changing only the adapter ring.
