- • Image Quality: Produces selectable 4‑ and 8‑line star effects while HD AGC optical glass reduces internal reflections and preserves colour.
- • Best for: Night, landscape and portrait photographers seeking creative highlights in low‑light scenes
- • Not ideal for: Photographers who need variable ND control rather than star effects
Variable star filter includes both 4 and 8 line cross settings for creative starbursts. Thin aircraft‑grade aluminium frame and 18‑layer nano‑coating protect glass and avoid dark corners.
Eye-catching star effects – thanks to selectable 4 and 8 line cross modes
Variable star filter offers two cross options in a single unit, converting bright points of light into multi‑ray starbursts for dramatic highlights. Selection between 4 and 8 line crosses changes the look from subtle to highly sparkly.
Switch between softer or more pronounced star patterns to suit street, skyline or portrait highlights, giving images a deliberate, creative sparkle.
Clear, true colours – with HD AGC optical glass and anti‑reflection coatings
HD AGC optical glass minimises reflections originating from the glass itself, while an 18‑layer nano coating reduces surface glare and offers dust‑proof, waterproof and anti‑mildew protection.
Maintain accurate colour rendition and minimise unwanted flares when shooting lights, so star effects do not wash out surrounding tones.
Wide compatibility without dark corners – thanks to an ultra‑thin 3.3mm aluminium frame
Frame manufactured from aircraft‑grade aluminium measures only 3.3mm in thickness, a slim profile that reduces the risk of vignetting on wider focal lengths.
Expect edge‑to‑edge coverage on compatible lenses, so wide‑angle night scenes retain full corners while gaining starburst highlights.
