Interesting results

Used with a DX Nikkor 18-200mm VR, polarization is very effective and rule gradually. It eliminates much glare and helps bring out the best of the nouances colors. It takes a little practice "grip" by doing tests but the results are generally very interesting.
The loss of brightness is obvious, therefore rather use in direct sunlight.
A little difficult to mount / dismount because of the very fine thickness. For the same reason, the standard Nikkor lens cap does not fit perfectly with the filter rises.
