ND Filter Hoya NDx4 49mm

NDx4 49mm Hoya NDx4 49mm neutral density filter reduces incoming light by 2 stops, enabling longer exposures and wider apertures without changing color balance. Made from optical glass with a slim profile, it minimizes vignetting on wide-angle lenses and is suitable for landscape and video work where bright conditions would otherwise cause overexposure.

Advantages

The Hoya NDx4 49mm filter delivers a consistent two-stop light reduction while preserving color neutrality and image sharpness. Its slim metal mount reduces the risk of vignetting on wide-angle lenses, and optical-grade glass minimizes distortion and color cast. The screw-in 49mm design provides straightforward attachment to compatible lenses.

Suitable for

• Landscape photography (long exposures for smooth water and cloud motion)
• Portraits and shallow depth-of-field effects in bright light
• Cine and video cameras with fixed shutter speeds filming very bright scenes
• Outdoor shooting with high-ISO film or sensors to avoid overexposure

How to use

Screw the Hoya NDx4 49mm filter onto the front thread of a compatible 49 mm lens. Use it when bright conditions would otherwise force very fast shutter speeds or small apertures: for example, to enable multi-second exposures for moving water, to allow wider apertures for subject separation, or to reduce effective sensitivity of high-ISO film or sensors. For video, attach the filter to avoid overexposure when shutter speed cannot be changed.

Usage recommendations

When composing long exposures, use a sturdy tripod and, if available, a remote shutter release or camera timer to avoid camera shake. Check for vignetting on very wide lenses and remove the filter if any darkening appears at the corners.
