: UV filters are one of the optical lens attachments that are still used today. Mainly the special filters ensure that the ultraviolet proportion is blocked in sunlight and cannot lead to unwanted colour distortion. The UV light invisible to human eyes can also have a slightly irritating effect on image sharpness - especially with very strong detail magnifications. In addition, a UV filter also has concrete mechanical advantages - due to its otherwise image-neutral properties, it can remain permanently on the lens and protects the expensive optics from damage. The Rollei premium round filter UV comes in nine different lens diameters: with 49, 52, 55, 58, 62, 67, 72, 77 and 82 mm, this high-quality round filter protects the windscreen against mechanical stress, scratches, dirt and sand.
