By now nearly all pictures that we get to see are digitally optimized or processed. Most analogue colour and effect filters can be virtually simulated today – including Polarizing filter.Their specialty lies in the infinitely variable removal - or addition - of reflections and mirror images on smooth, transparent, non- metallic surfaces such as water or glass. In addition, high-quality polarizing filters like the polarizing filter for 55mm camera lens by Rollei provide for more intense colors in the blue and green spectrum as well as for higher contrast and better differentiation.\n\nPremium Polarizing filter 55mm made from almost indestructible Gorilla® glass\nLike the current professional rectangular filters Rollei Premium Polarizing filter for 55mm camera lens of the newest generation are made from the legendary, resistant Gorilla®* glass from the American traditional manufacturer, Corning Inc.This special, distortion-free, extremely translucent glass resists adverse weather conditions, mechanical pressure or the effects of pointed or sharp objects to a great extent due to a special coating on the molecular level.If there is indeed an impairment of the surface, the coating prevents the edges from splintering. In addition, the Rollei Premium Round CPL Filter was provided with the special Luminance Coating, which determines decisively the outstanding optical properties, prevents reflections and mirror images and guarantees absolute colour neutrality indispensably, in order to be able to store the original picture information and characteristics on a lasting basis. The final anti-scratch layer lends the final hardness to the filter glass to resist mechanical effects and ensures that the worst contamination due to oil, water or mud can be removed again quickly and effortlessly.\n\nParticularly stringent quality management for the best Polarizer effect\nRollei premium round CPL filters 55mm are subject to our internally developed QM programme, which clearly goes beyond the usual industry standards. They benefit from really merciless testing and exclusion procedures, which involve everything from development to manufacturing up to the final delivery. The particularly high-quality Rollei premium round filters thus combine characteristics, which are normally excluded and provide you with optical precision objects, which are also a part of the most challenging photo safaris. You can obtain the filters in the nine most prevalent lens diameters.
