This is all right with pola filters and other special filters. But you cannot
use a lens shade of proper diameter. I know that there are many people
who think that with MC coating, this is not necessary. But they thought
and said the same when single-layer AR coatings were introduced, and
pros are conscientious shaders. They have seen to many pics ruined by
flare and bright spots (this is the instance when a bright spot is not quite
desirable ...)
