Hoya Variable Density II Filter 77mm

The new design of the Hoya Variable Density II Filter 77mm minimises the vignette effect often experienced when shooting on wide-angle lenses. Hoya engineers reconstructed the Variable Density frame, minimised the overall thickness and created a top frame that is one full size bigger than the original Variable Neutral Density Filter.

Why Variable Density II Filter 77mm areImportant

Variable density filters are widely used because they can replace a set of solid ND filters by providing a range density that can be adjusted according to the desired exposure settings.

In still shooting, variable density filters lower the shutter speed according to the photographer's intentions when the shutter speed cannot be lowed due to camera limits.

Variable density filters can also increase the amount of boke when shooting in the over-lit conditions, thus, preventing the image from overexposure.

In video shooting, it is fundamental to keep the shutter speed fitting the frame rate setting. That is, to keep it equal to double the frame rate for optimal results. This is because, unlike still photography, an excessively fast shutter speed may create a jarring effect and produce afterimages that will not look good in the final video.

For Longer Exposures

Without changing the aperture, the HOYA Variable Density II provides the freedom to change the shutter speed according the effect desired. Effective for motion blurring effects like waterfalls, cars or blurred panning movement to make the subject stand out from the background.

For Wider Apertures

Allows wider apertures in over-lit conditions be used to decrease depth-of-field, literally focusing more attention on the subject.
