Sigma 95mm Protector
♥ Design that is conscious of optical quality
It is designed to avoid vignetting or the decrease in peripheral light quantities especially when the thinner wide type filters are used with SIGMA lenses.
♥ Ultra Low-reflection
By incorporating Sigma's Super Multi-Layer Coating, the filter reduces flare and ghosting. In addition, black rimmed glass eliminates unnecessary internal reflections, and provides high performance for both digital cameras and film cameras.
♥ Antistatic function
With excellent antistatic performance, the filter prevents microscopic dust clinging to the surface. Even if the lens gets soiled, dust can be easily removed using an air-blower.
♥ Thinner wide type (from 46mm to 82mm)
By incorporating thinner frame (except 86mm, 95mm and 105mm) to avoid vignetting even with super wide-angle lenses, it is ideal for various types of lenses from wide-angle to telephoto. Moreover, a lens cap can be attached as the edge of frame is threaded.
