Hoya Variable Density II Camera Filter 55 mm

The Hoya Variable Density II 55 mm camera filter is a versatile optical tool designed to provide precise control over the amount of light entering your lens. By offering an adjustable neutral density range from 1.5 to 9 f-stops (ND3-400), this filter allows photographers and videographers to manage exposure settings without the need to constantly adjust aperture or shutter speed. The updated design features a rotatable frame with a convenient adjustment knob, ensuring smooth operation and improved handling during shooting sessions.

Advantages

This filter serves as a comprehensive solution that replaces the need for carrying multiple solid neutral density filters. Its unique construction includes a specialized rotatable frame that is wider than the fixed base, which significantly minimizes the risk of vignetting when using wide-angle lenses. The filter is particularly beneficial for achieving a cinematic look in video production by allowing for optimal shutter speed settings relative to frame rates. Furthermore, it provides the flexibility to use wider apertures in bright lighting conditions, which is essential for isolating subjects through a shallow depth of field. The durable build ensures consistent image quality across the entire density range.

Suitable for

• Long exposure photography of moving subjects like waterfalls or traffic
• Cinematic video recording in bright daylight
• Portrait photography requiring wide apertures in high-light environments
• Maintaining consistent shutter speeds for professional video frame rates

When it may not be suitable

This filter may not be ideal for ultra-wide-angle lenses, as the physical thickness of the variable density mechanism can occasionally cause peripheral darkening or vignetting at the widest focal lengths. Additionally, users seeking extreme long exposures beyond the 9-stop range may require dedicated solid ND filters for specific technical applications.

Key specifications

• Filter size: 55 mm
• Density range: ND3 to ND400 (1.5 to 9 f-stops)
• Frame design: Rotatable with adjustment knob
• Compatibility: Supports one size larger lens cap

How to use

To use the Hoya Variable Density II, simply screw the filter onto the front thread of your 55 mm lens. Once attached, rotate the outer ring using the integrated knob to adjust the light transmission to your desired level. For video, monitor your exposure settings to ensure the shutter speed is set to double your frame rate for natural motion blur. When shooting stills, adjust the density until your light meter indicates the correct exposure for your chosen aperture and ISO settings.

What to consider before purchase

• Verify that your lens has a 55 mm filter thread diameter
• Note that the filter frame is slightly larger than the lens diameter, so a larger lens cap may be required
• Ensure your lens focal length is compatible to avoid potential vignetting at extreme wide angles

Usage recommendations

For the best results in video production, always prioritize setting your shutter speed to double your frame rate before adjusting the filter density. This ensures the most natural motion blur and a professional cinematic appearance in your final footage.
