Hoya Variable Density II 67mm Filter (ND3 to ND400)
The HOYA Variable Density II filter provides a convenient way to maintain exposure control by being able to vary the amount of light entering the camera by 1.5 to 9 stops. The precision built-in double ring design allows the outer ring rotates to control amount of neutral density effect anywhere within the 1.5-9 stop range. This double-ring design is also thin to reduce the likelihood of vignetting with wide-angle lenses. This control allows for many special effects such as being able to control depth of field by using a wider aperture or create or control motion blur by being able to choose just the right slower shutter speeds for perfect blurring.
The HOYA Variable Density II 67mm filter can take the place of a range of graded ND filters which saves money by only needing to buy one filter and saves time on location or on set by not needing to change filters constantly to change the effect, just turn the right to get the effect you want. The HOYA Variable Density filter puts you in control.
Variable Density II filters, and ND filters in general have these main uses:
- Slow down shutter speed for motion blurring effects like waterfalls, blurred panning movement to make the subject stand out.
- Allow wider apertures to be used to decrease depth-of-field, literally focusing more attention on the subject.
- Allow higher ISO films to be used in brighter lighting conditions.
- Allow video cameras, which have a fixed shutter-speed range, to film in bright conditions such as the beach or snow.
For best results, we recommend using a tripod when photographing with slow shutter speeds.
The Variable Density II filter uses high-quality optical glass from Hoya Corporation, the worlds largest optical glass manufacturer.
