Flattering skin tones – Thanks to Black Diffusion 1/8 filter
Black diffusion 1/8 reduces highlights and lowers glare by scattering intense light across the image plane, creating a subtle halo that mutes sharp transitions. The effect softens fine blemishes while leaving midtones intact.
Portraits gain a gentle, film-like glow that flatters subjects and reduces the need for heavy skin retouching during post-production.
True-to-life colour – With HD AGC optical glass and anti-reflection coating
HD AGC optical glass limits reflections from the filter surface so captured colours remain accurate and contrast is preserved. The optical design reduces internal flare that can shift colour balance.
Colours stay faithful, so less correction is needed in editing and skin tones remain natural under varied lighting.
Field-ready durability – With 18-layer nano-coating and slim aircraft-grade frame
An 18-layer nano-coating delivers anti-reflection, dust-proof, waterproof and anti-mildew properties, while a 3.3mm-thick aircraft-grade aluminium frame keeps the profile thin to prevent vignetting.
Durable protection for the front element and a slim mount suitable for many lenses, plus three microfibre cloths included for safe maintenance.
