Kenko Variable NDX Filter PL FADER ND3-ND400 Filter
Kenko’s variable Neutral Density filter provides the equivalent brightness range of ND 2.5 to ND 1,000 (practical use being up to ND450).
The singular versatility of the Variable NDX filter replaces a whole set of stacking neutral density filters and also removes vignetting. The filter size is 77-22. It is Digital Multi-coated (DMC) and is designed for HDSLR movies. Specific for longer exposures and wider apertures, the filter prevents overexposure.
The 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. Without changing the aperture, the PL FADER allows the user to change the shutter speed according to the effect desired. With the PL FADER, the shutter speed remains constant for a wide aperture creating a blurred background effect. The PL FADER eliminates the overexposure even with a shutter speed of 1/8000 seconds, a large aperture of f/1.4 or f/1.2.
