Hoya PROND1000 67mm Neutral Density Filter

Neutral Density Filter with 10-Stop Light Reduction

The Hoya PROND1000 is a high-quality neutral density filter designed to reduce the amount of light entering your camera lens by 10 stops, equivalent to an ND optical density of 3.0. This allows for the use of wider apertures or slower shutter speeds to achieve creative and dramatic effects in bright lighting conditions.

ACCU-ND Technology for True Neutral Color Balance

The filter features Hoya's exclusive ACCU-ND technology, which provides a truly neutral color balance without introducing any noticeable color cast to your images. The metallic ACCU-ND coating is applied on both the front and back of the clear optical glass, ensuring consistent color neutrality across different filter densities.

Consistent Color Balance Across Filter Densities

The metallic ACCU-ND coating prevents color shifts when switching between filters of different densities, a common issue with other neutral density filter series. This allows you to set your white balance once and maintain consistent color balance even when changing filters due to lighting changes or creative needs.

Durable and Low-Profile Design

All Hoya PROND filters, including the ND1000, feature a low-profile one-piece aluminum frame. The thin frame securely holds the glass parallel to the sensor and is compatible with super-wide angle lenses, minimizing vignetting.

Key Specifications:

• Filter factor: 1000 (10 stops light reduction)
• Optical density: 3.0
• Filter thread size: 67 mm
• Clear optical glass with metallic ACCU-ND coating front and back
• Low-profile one-piece aluminum frame

Applications

The extreme light reduction of the PROND1000 enables shutter speeds as slow as 16 seconds or more in daylight, allowing for significant motion blur or even disappearance of moving subjects depending on speed. It is ideal for still photography and HDSLR video where precise control over exposure and creative effects are desired.
