Polarizing filters test 2015 - NiSi Wide Band PRO MC C-PL

NiSi is a young Chinese company specializing in photographic filters. They were launched on the market not long before the publication of our first test. It’s worth checking whether their brand name competitors have anything to worry about.

Design, usage and summary

The filter makes a better impression than the DUS version. A screwed-on ring with a marker of polarization azimuth (the false reading by about 10 degrees could have been smaller). It works with a bit of uneven resistance but its parts fit well together and the surfaces are covered by broadband MC coatings which are relatively easy to clean. The filter is produced in Japan.

A flat spectrum characteristics in the visible spectrum. Good mean transmission and the extinction coefficient for the middle of the spectrum, a bit worse on both ends. Like in the previous model the filter becomes translucent quickly in infrared.
