## Long description

The K&F SB9719 Shimm Nano C HMC 77 mm glossy diffuser is an optical filter that fits lenses with a 77 mm filter thread and is engineered to soften highlights and reduce contrast for portrait and product photography. The diffuser surface scatters light from strong specular highlights to produce a subtle glow and gentle smoothing of skin and reflective surfaces. A multi-coated HMC (High Multi-Coating) layer improves light transmission and reduces internal reflections, preserving color fidelity and overall image clarity while delivering a controlled diffusion effect.
Advantages
This glossy diffuser provides a natural-looking softening of highlights without significantly altering color balance or introducing strong color casts. The HMC coating minimizes ghosting and flare, ensuring consistent performance under varied lighting conditions. The 77 mm standard thread makes the filter compatible with many telephoto and portrait lenses, allowing photographers to achieve highlight diffusion without changing lighting setups or using larger softbox modifiers. The build design maintains secure mounting and optical alignment on the lens.
Suitable for
Portrait photography to reduce specular highlights and smooth skin appearance
Product photography for taming reflections on glossy surfaces
On-location shoots where softer highlights are needed without additional lighting gear
Videography that requires subtle glow and controlled contrast
Key specifications
Filter type: glossy diffuser
Filter size: 77 mm thread
Optical coating: high multi-coating (HMC) for improved transmission and reduced reflections
Effect: softening of highlights and mild contrast reduction with subtle glow
Mechanical: screw-mount design for standard 77 mm filter threads
How to use
Screw the filter onto the front of a lens with a 77 mm thread until it is snug; avoid over-tightening. Compose and expose as you normally would, then evaluate highlights and contrast in the scene. Because the diffuser subtly spreads specular light, you may need to adjust exposure or highlight roll-off settings, especially in high-contrast situations. The filter can remain on the lens for both stills and video; remove or replace it when sharper, high-contrast rendering is required.
Usage recommendations
For portraits, position your key light and check highlight placement before attaching the filter to ensure the diffusion enhances skin tones without flattening facial details. For products with strong specular reflections, try rotating the camera or changing angle slightly to balance the diffused highlights. Clean the filter with a soft lens cloth and suitable cleaning fluid; store in a protective case when not in use to preserve the HMC coating.
