The filter limits UV rays so that photos are clearer, especially at high altitudes. Because it is color neutral and does not cause light loss, it is used as lens protection and should always be mounted. It protects the optics from scratches, dust, fingerprints, and more. The SLIM series filter has a thickness of only 3mm (regular UV filters are about 5mm). Thanks to this, there is no fear of lens vignetting. The filter features eight anti-reflective coatings, which make its optical quality comparable to the highest quality filters. It is made from optical glass with a thickness of just 1mm. The filter is suitable for both traditional and digital cameras.
