: Kenko 58mm PL FADER Variable Neutral Density (ND3 to ND400) Camera Lens Filters : Electronics. 1. 5 to 9 stop of neutral Density (ND3 to ND400) 。 Super clear assai optical glass 。 All Metal ring with optional control stick 。 Made in Japan 。 Optional control lever included 。 The PL fader is a variable neutral Density filter that uses two high-transparency polarizing film layers to control the amount of light that passes through the filter and into camera lens. without changing the aperture, the PL fader allows the freedom to change the shutter speed according 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. 2 can cause overexposure/highlight clipping. With the PL fader, this overexposure is eliminated. for video enabled and cinema cameras, use the PL fader to easily adjust depth of field or shutter angle. 。。。
