To ensure high-performance, every Protector Filter incorporates SIGMA’s Super Multi-Layer Coating that effectively reduces flare and ghosting. The black rimmed glass further increases performances by elimination unnecessary internal reflections.
SIGMA’s Super Multi-Layer Coating suppresses flare and ghosting by minimising reflections within the lens. All lenses in the current Sigma range feature this technology. On digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, the coating is highly effective, ensuring images with outstanding contrast.
