The Sigma Protector has been designed to suit Sigma's range of lenses. The Sigma Protector is developed to protect the lens surface from dirt and dust as well as scratches. It is an ideal filter for regular use as it is completely colourless so does not affect colour reproduction. Interchangeable lenses are required to perform their best in different shooting conditions and this protection filter will certainly ensure their performance to the fullest.
Optimised design for SIGMA lenses
Design that is conscious of optical quality - This filter has been specifically designed to avoid vignetting, the decrease in peripheral light.
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.
Thinner Frame
By incorporating thinner frame 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.
Newly designed case for safety and utility
Thanks to Elastomer resin, filters do not move in the case even when it is carried around. The case is half-transparent so that content can be recognized from outside.
