Variable density camera filter Hoya Variable Density II 58 mm

The Hoya Variable Density II 58 mm filter is a versatile optical tool designed to provide precise control over light intake for both photography and videography. By offering a variable neutral density range from ND3 to ND400, this filter allows users to adjust exposure settings smoothly without the need to carry multiple fixed ND filters. The updated design features a rotatable frame with an integrated knob, ensuring ergonomic operation and easy adjustments in the field. Its construction is specifically engineered to minimize vignetting, making it a reliable choice for various shooting conditions.

Advantages

This filter offers significant flexibility by enabling photographers and videographers to manipulate shutter speeds and apertures independently of ambient lighting. By reducing the amount of light entering the lens, it allows for the use of wider apertures in bright conditions to achieve a shallow depth of field, or the use of slower shutter speeds to capture motion blur in subjects like flowing water or moving vehicles. For video creators, it is an essential tool for maintaining optimal shutter speeds relative to frame rates, which is critical for achieving natural, cinematic motion. The improved frame design not only facilitates easier rotation but also accommodates larger lens caps, enhancing overall usability and convenience.

Suitable for

• Landscape photography requiring long exposure effects
• Cinematic video production in bright outdoor environments
• Portrait photography with wide apertures in daylight
• Controlling exposure when camera shutter speed limits are reached

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 introduce vignetting at the edges of the frame. It is generally recommended to avoid using this filter on lenses with focal lengths shorter than 13mm for APS-C sensors or 24mm for full-frame sensors.

Key specifications

• Filter diameter: 58 mm
• Density range: ND3 to ND400 (1.5 to 9 f-stops)
• Frame type: Rotatable with adjustment knob
• Color: Black
• Material: Optical glass with specialized frame construction

How to use

To use the Hoya Variable Density II filter, screw it onto the front thread of your lens until secure. Once attached, you can adjust the density by rotating the outer ring using the integrated knob. Observe your camera's exposure meter or the live view display to determine the desired light reduction. For video, ensure your shutter speed is set to double your frame rate, then rotate the filter until the exposure is correctly balanced. If you are using a lens cap, note that you may need a cap one size larger than the filter diameter due to the frame design.

What to consider before purchase

• Check your lens filter thread size to ensure it matches the 58 mm diameter.
• Verify your lens focal length to avoid potential vignetting issues.
• Consider if your current lens cap is compatible or if you need a larger size.
• Assess your primary use case, such as video production or long-exposure photography.

Usage recommendations: When shooting at the maximum density settings, be aware that cross-polarization patterns may appear in the image. It is recommended to adjust the rotation until the desired exposure is achieved while monitoring the frame for any unwanted artifacts.
