The NiSi Filter Holder M75 is made especially for mirrorless cameras and compacts and is compatible with 75x80 mm or 75x100 mm square filters (2 mm thick) from NiSi and other brands.
The filter holder can be rotated 360 degrees and can also be locked in any desired position. It's made from aviation-grade aluminium and has a new design for locking the filters in place, which makes inserting and removing very smoth.
The standard mount fits a 67 mm filter-thread but the holder can be used with adaptors for filter threads from 40,5 mm to 62 mm. Adaptors are sold separately (see list below).
This kit comes complete with an ultra slim 67 mm circular NiSi Polarizing filter (CPL). With a unique design, the polarizing filter can be rotated via a small wheel on the back of the holder. It means you don't have to detach any square filters to be able to adjust the polarizer.
The NiSi Filter Holder M75 can be used on APS-C lenses with focal lengths as short as 11 mm (ultra-wide-angle) without causing any vignetting (dark corners). It may also be used on 10 mm lenses, altough slight vignetting can occur if the holder is rotated to a 45 degree angle.
With cameras in the Micro Four Thirds system, the filter holder can be used on lenses with a focal length as short as 8 mm without risk of vignetting.
