UV and ND4 filter work perfectly. the effects are superb. I am very happy. The lens hood is working as intended. Nothing to say. By cons, the PLC filter does not work. When turning the two glasses rotate at the same time, so it has no effect. Because we can not communicate with the seller to say and it's too complicated to return the defective product. I am content articles that work well. Too bad this impact spoils the pleasure.
