## Summary description

Half ND8 neutral density filter by K&F for 77mm lens threads, made of optical glass.

Fits lenses with 77mm filter thread, suitable for handheld or tripod use.

## Long description

The K&F Half ND8 Neutral Density 77mm Camera Filter is a graduated (half) neutral density filter made of optical glass designed for lenses with a 77mm filter thread. The filter reduces light transmission by three stops in the darkened portion while keeping the other part of the frame clear, enabling better dynamic range control when shooting scenes with bright skies or reflective surfaces. Designed for landscape and architectural photography, the compact glass construction mounts directly to the front of compatible lenses and can be used for handheld or tripod-mounted shooting.
Advantages
This half ND8 filter provides precise exposure control across high-contrast scenes without altering color balance or sharpness when used correctly. The optical glass construction ensures image clarity and consistent neutral density across the shaded area, while the 77mm diameter makes it compatible with a wide range of professional lenses. The graduated design preserves detail in highlights while retaining correct exposure in the foreground, reducing the need for heavy post-processing.
Suitable for
Landscape photography with bright skies and darker foregrounds
Architectural and cityscape shots where sky exposure needs balancing
Outdoor portraiture to manage backlit conditions
Handheld or tripod-based shooting where partial exposure reduction is required
Key specifications
Filter type: Graduated (half) neutral density
Density: ND8 (approx. 3 stops reduction)
Material: Optical glass
Thread size: 77 mm
Coverage: Half-frame graduated transition
How to use
Attach the filter to a lens with a 77mm filter thread by screwing it onto the front of the lens or mounting it in a compatible holder. Position the darkened half of the filter over the brightest parts of the scene (typically the sky) and rotate or slide the filter as needed to align the graduation with the horizon or architectural edges. Meter for the area of the frame you want to retain detail in or use manual exposure settings; apply approximately three stops of exposure compensation relative to the unfiltered portion. Check focus and framing after mounting, as the filter may require slight adjustments for optimal composition.
Usage recommendations
For best results, use the K&F Half ND8 when the horizon or bright area is reasonably straight and occupies only part of the frame. When shooting scenes with complex or uneven horizons, consider combining the filter with exposure bracketing or using graduated stacking techniques in post-processing. Clean the glass with a microfiber cloth before use to avoid flare and maintain image sharpness.
