Neutral Density Filter Hoya HD Mk II IRND1000 77mm

The Neutral Density Filter Hoya HD Mk II IRND1000 77mm reduces incoming light by 10 stops, enabling long exposures and wider apertures in bright conditions. Constructed with Hoya's optical glass and multi-coating technology, this ND1000 filter preserves color fidelity and minimizes reflections while supporting creative techniques such as motion blur of water, clouds, or moving subjects. The 77mm diameter fits lenses with a 77mm thread and is intended for photographers who need precise exposure control without altering color balance.

Advantages

The HD Mk II IRND1000 features high-quality optical glass and durable multi-coatings that reduce flare and ghosting while maintaining image sharpness. The filter's neutral density characteristic provides a consistent 10-stop reduction across the visible spectrum, and the infrared (IR) control minimizes color cast from IR contamination. Machined filter ring and slim profile help avoid vignetting on wide-angle lenses, and the robust construction supports repeated use in outdoor conditions.

Suitable for

• Landscape long exposures to smooth water and cloud movement
• Urban and architectural photography requiring motion separation
• Portraits or shallow depth-of-field shots in very bright light using wide apertures
• Time-lapse sequences where controlled exposure across frames is needed

Key specifications

• Filter type: Neutral Density (10-stop)
• Optical construction: high-quality optical glass
• Coatings: multi-coating with infrared control
• Diameter: 77 mm thread
• Profile: slim/machined metal ring to reduce vignetting
• Light reduction: approx. 10 stops

How to use

Mount the Hoya HD Mk II IRND1000 onto a lens with a 77mm filter thread by gently screwing the filter into place until it is snug. For long exposures, use a tripod to stabilize the camera and compose your shot before attaching the filter if possible. Meter exposure with the filter attached or calculate exposure compensation for a 10-stop reduction; use live view or an exposure meter to confirm. When shooting in very bright or changing light, bracket exposures or use exposure modes that allow manual control of shutter speed and aperture. Remove the filter carefully after use and store it in its protective case to preserve the coatings.

Usage recommendations

For best results, combine the ND1000 with a sturdy tripod and a remote shutter or camera timer to avoid camera shake during long exposures. Check for any color cast in RAW files and apply minor color correction if necessary; the IR control coating reduces but may not completely eliminate infrared-induced shifts. Clean the filter with a soft microfiber cloth and appropriate lens cleaner to maintain coating performance, and avoid touching the glass surface with bare fingers.
