The Hoya Variable Density II filter is a density adjustable filter with an ND range from 1.5 to 9 stops (ND3 400). It has a newly designed rotable frame with convenient knob, allowing for better operation.
The HOYA Variable Density II filter utilizes 2 polarized glass elements that when rotated allow you to control the optical density of the filter. This allows you to adjust the brightness/darkness of the filter to have more control over the exposure settings of the camera. This filter can reduce light transmittance from ND3 (1 2/3 stops, 0.5) to
ND400 (8 2/3 stops, 2.6). This allows for more creative shutter speed and aperture combinations to create the desired effect.
Notes: This filter does not have front filter thread so it may be tricky to attach a lens cap to protect the filter during transport. We recommend removing the filter and placing it into the included case when not in use.
Highlighted features: When using this filter at its maximum ND value and beyond (∇ matches with X), a common and unavoidable aberration, that is common to all Variable ND filters, may occur in the image. This is known as crosspolarization and will take the form of a darkened “X” pattern through the middle of the image and corners. The pattern is exaggerated and may occur earlier in the variable density range on lenses with a focal length wider than 28mm (for Full Frame sensors). Please use focal lengths 28mm and up for best results.
Available sizes: 52, 55, 58, 62, 67, 72, 77, 82 mm
