Very well packaged, the product is easily placed on the lens of my Lumix DMC FZ200 and perfectly protects without significant loss of quality.
In addition, it is possible to leave it at home, and place without any difficulty, the original cap.
From inside my house without Polarizer, my Lumix made me focus on the curtain and the reflection of the glass, whereas with the filter, it makes its development outside on the subject, without difficulty .
Tested by rainy weather, there is a light loss of about two stops to two and a half, which does not disturb too my Lumix opening 2.8 on all focal lengths, and which earned me to do beautiful yarns raindrops, screwing my two filters on each other !! -D
Eh yes !! It's possible, and even the lens cap fits over all without any difficulty!
So that's positive, but you can be there waiting for you with Hoya / Tokina Made in Japan ...
Great product that I recommend without hesitation to those who want quality.
