If you've shot with a polarizer and separate ND filter on a wide-angle lens before, you'll likely have experienced vignetting, especially when shooting wider than 20mm. The new Dark CPL is designed to combine polarization and neutral density in one individual filter and allow you to capture images without vignetting at focal lengths as wide as 16mm. More specifically, the Dark CPL is a combination of our cpl and Neutral Density filters in one piece.
