Kenko 67mm PL Fader Variable Neutral Density Filter

* Without changing the aperture, the PL Fader allows the freedom to change the shutter speed according to the effect desired

* With the PL Fader, the shutter speed remains constant for a wide aperture easily creating a blurred background effect

* Even with a shutter speed of 1/8000 seconds, a large aperture of F1.4 or F1.9 can cause overexposure/highlight clipping. With the PL Fader, this overexposure is eliminatedThe PL Fader uses two high-transparency polarizing film layers to control the amount of light that passes through the filter and into the camera lens.
