Camera Variable Density Filter Hoya II 82mm – adjustable ND filter, 82 mm thread

The Hoya 77mm Variable Density Filter (Model Hoya II) provides adjustable light reduction between approximately 1.5 and 9 stops, allowing precise control of exposure and creative effects. Its slim double-ring design reduces the risk of vignetting with wide-angle lenses while enabling smooth rotation of the outer ring to set the desired neutral density level. The filter can replace several fixed ND filters, saving time and money by avoiding frequent filter changes.

Advantages

The slim double-ring construction minimizes vignetting and maintains compatibility with wide-angle lenses. The continuously variable density range (1.5–9 stops) lets you control depth of field by using wider apertures and achieve controlled motion blur by selecting appropriate shutter speeds. Using one variable filter removes the need to carry multiple fixed ND filters.

Suitable for

• Landscape photography — long exposures for moving water and clouds
• Portraits in bright light — wider apertures for shallow depth of field
• Urban and street photography — motion blur for moving vehicles and people
• Bright outdoor conditions — beaches, snow scenes, and midday sun

Key specifications

• Brand: Hoya
• Model: Variable Density Filter Hoya II
• Mount/thread reference: designed for lenses with 77mm thread (product front frame increases cap size)
• Filter size note: when attached to a 77mm lens the enlarged front requires an 82mm lens cap
• Density range: approximately 1.5 to 9 stops (variable ND)

How to use

Attach the filter to the lens thread and rotate the outer ring to set the desired density. Monitor exposure and adjust shutter speed and aperture as needed to achieve the intended effect — longer exposures for motion blur or wider apertures for shallower depth of field. Check the viewfinder or live view for vignetting or color shifts and fine-tune the position accordingly.

Usage recommendations

When the filter is mounted on a 77mm lens, the widened front frame increases the lens cap requirement to 82mm; this design reduces vignetting. Use the variable ND for scenes with strong highlights or when you want flexible control without swapping multiple fixed ND filters.
