82mm Master Magnetic CPL Filter

For use with FH100 mkIII Filter Holder

The MAMCPL82 82mm CPL from Benro is a magnetic circular polariser filter dedicated for use with the filter holders with a magnetic ring. Unlike standard CPL filters, this 82mm CPL does not have screw thread or a rotating front element, and the rotation is achieved by a mechanism on the holder. Without the rotating front element, the CPL is much easier to attach and remove compared to the previous system where the CPL had a front rotating element. The CPL's ultra thin design, which is constructed from ultra-thin Schott B270 glass and thin ring, reduces the occurence of vignetting at extreme wide angle. In addition, flat polished HD glass minimises refraction of light, thus minimising loss of resolution. Flare and chromatic aberration is reduced by the application of a 16-layer ULCA coating while polarised light is reduced by Japanese polarisation. The scratch resistant glass also receives a WMC coating to render the filter water and oil repellent for easier cleaner.

Thanks to the extremely thin design, it is possible to use this filter on many 15mm full frame lenses, with exception for a handful of lenses that have a different construction, which can cause some filters vignetting. Tamron 24-70f/2.8 G2, Sony 16-35 f/2.8 GM, and Tamron 24-70 f/15-35mm f/2.8L IS USM are examples of such lenses. In such scenario, the MAMCPL95 95mm Master Magnetic CPL is recommended.
