Hoya Solas Variable ND Filter (77mm, 1.3 to 8.7-Stop)

This 1.3 to 8.7-stop, 77mm Hoya Solas Variable ND Filter is a solid variable neutral density filter that provides an exposure reduction of 1.3 to 8.7 stops. The 0.4 to 2.6 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject.
