ROUND KW Revolution Magnetic CPL polarizing filter
ROUND KW Revolution Magnetic CPL polarizing filter
Our magnetic round filters from the KW Revolution series are made of the same tempered glass as our Wolverine rectangular filters and therefore have the same excellent imaging performance, extremely low color shift and high impact resistance. In photography, polarizing filters are often used to minimize light reflections or to increase the intensity of natural blue and green tones and also to increase the contrast range. With a twist of the CPL filter, you can continuously remove unwanted reflections and reflections on surfaces such as glass or water. This correction can usually no longer be implemented in post-processing due to the missing image information. The magnetic polarization filter comes with a matching magnetic adapter ring, which can also be used with our magnetic ND filters with the same diameter. Frame material: aluminum / magnetic strips Material glass: tempered optical glass Scope of delivery: 1x KW Revolution Magnetic CPL polarizing filter (silver frame) 1x magnetic adapter ring for screwing onto the lens 1x storage box
