The Exus series features a matte black metal edge and a black optical side. The Exus filters are the best of their kind because they are dirt, oil, and water-resistant and have an anti-static coating. These top-line filters can be counted among the best in the world. The Marumi EXUS Protect 52 mm filter is a neutral protection filter that safeguards the lens without unwanted filter effects. A standard filter often causes significant reflection and distortion on the camera sensor. This Exus protection filter has a special coating that reduces the reflection of incoming light to less than 0.3%.
