NOTE: Because of its action, the Cokin Skylight and UV filters can be left in the Cokin filter holder most of the time. However, the use of multiple filters must be carefully monitored. Stacking of multiple filters can lead to "vignetting", which is a "clipping" of the four corners of the image and shows up as black corners.
This filter measures 130 X 170mm and only fits the Cokin X-PRO series holder.
