Neutral density camera filter Hoya PROND4 55 mm

The Hoya PROND4 55 mm neutral density camera filter reduces incoming light by 2 stops (ND 0.6) while maintaining a neutral color balance. Made from Hoya clear optical glass with Metallic ACCU‑ND coating on both sides and mounted in a durable black frame, this filter is intended for still photography and HDSLR video where consistent color neutrality is required across different densities.

Advantages

The ACCU‑ND technology and Metallic ACCU‑ND coatings provide a consistent, neutral color balance with minimal color cast when compared to many other neutral density filters. The coating is applied front and back to preserve image quality, and the filter’s 2‑stop light reduction allows use of wider apertures or slower shutter speeds in bright conditions without altering color rendition.

Suitable for

• Landscape photography requiring controlled exposure in bright light
• Portraits where wider aperture is needed outdoors
• Long exposure and motion‑blur effects with still cameras and HDSLRs
• Situations requiring consistent white balance when changing filters

Key specifications

• Mount diameter: 55 mm
• Light reduction: 2 stops (ND 0.6)
• Glass: Hoya clear optical glass
• Coating: Metallic ACCU‑ND front and back
• Series: Hoya PROND (available densities from 2 to 10 stops)
• MPN: YPND000455

How to use

Screw the 55 mm Hoya PROND4 filter onto the front of a lens with a matching filter thread. Set exposure and white balance as usual; the filter reduces light by 2 stops, allowing either a wider aperture or a slower shutter speed for creative control. If you change to a different PROND density, you can keep the same white balance setting thanks to the ACCU‑ND coating.

Usage recommendations

For best results, use the PROND4 with lenses that accept 55 mm filters and set white balance once when shooting a sequence. Clean the glass with a lens cloth and appropriate cleaning solution to avoid scratches and maintain coating performance.
