Product Description Ultraviolet radiation is not visible to the human eye but can lead to unwanted optical effects in photography: On the one hand, the UV component in the natural scattered light, which is also known as Raleigh radiation, provides for a strong blue colour, whose full extent is often noticeable only in retrospect. On the other hand the chromatic aberration of high UV lighting components leads to blurriness in the picture. Nowadays, special UV blocking filters are also gladly used in order to prevent these impairments effectively. However, UV filters - and especially the very durable Rollei Extremium round UV filters - have yet another task: Since they affect the transmitted light only minimally and barely darken it, they simply remain as an additional protective mechanism on the lens. High-quality, valuable lenses usually have to be repaired, which is time-consuming and expensive, if the front element was damaged. Rollei Extremium filters are made of extremely resistant Gorilla glass and an almost indestructible titanium filter ring. An extensive bath in a special hot liquid ensures that there is an effective exchange of ions on the molecular level in Gorilla glass and a greatly increased surface tension, which defies sharp edged and pointed objects and prevents further splintering of material even in the event of deeper scratches. And even if this barrier falls due to undue force, the filter can simply be unscrewed and the lens remains intact. Box Contains 1x Rollei Extremium Round Filter UV
