Circular Polarising Filter CPL 49mm

New Visico circular polarising filter 49mm Manufactured by Vistarfoto.
The filter screws firmly on to the lens and the actual polarising glass has its own mount which rotates separately.

There are two varieties of polarising filters- linear and circular. Although they're both physically round, the linear variety can have an effect on the autofocus or metering accuracy of any camera that uses a semi-silvered mirror or prism to split the light entering the viewfinder. This is known as a beam splitter and is used by most modern film SLRs to calculate exposure and focusing distance. As a rule use a circular filter if you have an autofocus camera of this type or a manual focus model with a spot meter. An excellent filter.
