Kenko 77mm ND PL Fader Filter
Without changing the aperture or ISO, the PL Fader allows the photographer freedom to dramatically reduce shutter speeds and achieve beautiful blurring of water and skies. It can even hide traffic and pedestrians from a busy scene.
The PL Fader allows the shutter speed to remain constant and enables the use of a much wider aperture to easily create a blurred background effect.
Prevent Overexposure / Highlight Clipping:
Even with a shutter speed of 1/8000sec, a large aperture of F1.4 or F1.2 can cause overexposure and highlight clipping. With the PL Fader, this overexposure can be eliminated.
Flexible Light Control for HDSLR Video:
For HD video-enabled cameras, the PL Fader provides easily adjustable light control.
