Neutral Density Half-Frame Filter K&F 82mm ND8 (KF01.1546) Glass

K&F 82mm ND8 half-frame neutral density filter (glass) reduces incoming light by three stops when placed over part of the lens, allowing selective exposure control for creative long exposures and motion blur. The filter is sized for lenses with an 82 mm filter thread and is designed as a half-frame piece so that one portion of the image is darkened while the other remains at normal exposure. This enables controlled balancing between bright skies and darker foregrounds, smoother water and cloud motion, and extended shutter times without affecting the entire frame.

Advantages

The glass construction provides consistent optical quality and color neutrality across the filtered area. A three-stop light reduction (ND8) gives predictable exposure extension suitable for many landscape and motion effects while avoiding excessive color cast. The half-frame format offers precise control over which part of the scene is affected, simplifying sky-to-foreground balancing without the need for complex post-processing. Compatible with 82 mm screw-in filter systems, the filter mounts securely and maintains lens alignment.

Suitable for

• Landscape photography with bright skies and darker foregrounds
• Waterfall and river scenes to create smooth water effects
• Coastal and seascape shots to blur moving waves
• Long-exposure cityscapes where part of the frame requires darkening
• Creative portrait or product shots needing selective exposure control

Key specifications

• Filter type: half-frame neutral density (ND) glass
• Light reduction: 3 stops (ND8)
• Mount type: 82 mm screw-in filter thread
• Material: optical glass element
• Coverage: partial-frame (half) coverage to darken only part of the image

How to use

Attach the filter to a lens with an 82 mm thread and position the darkened half over the portion of the scene you want to reduce in exposure. Compose and level the camera so that the transition line between filtered and unfiltered areas aligns with the horizon or another reference in the scene. Meter exposure for the unfiltered portion or use manual exposure, then adjust shutter speed to achieve the desired motion blur or exposure balance. Small rotational or vertical adjustments of the filter allow fine-tuning of the transition position.

Usage recommendations

The filter performs best when used on a tripod for precise composition and stable long exposures. Use live view or electronic level to align the split line accurately; when making large exposure changes carry a remote release or use mirror lock-up where applicable. Clean the glass surfaces before use and store the filter in a protective case to avoid scratches.
