Q: 6. I bouth this item and the 10-18mm Canon lens and I was using the UV with the polarizer attached to it and when looking through the view I see black borders around the image, is this ok? I removed both filters and took the picture again and the black border was not there.

A: That is called vignette. It means that the filters are too thick to be used with that lens and you will get vignette in your images. Chances are if you set the lens to 18mm you might not have vignette. In general it is not a good idea to stack filters so when you use a polarizer you should take off the UV filter. It will reduce the amount of vignette. But with that wide a lens you still might get vignette.

Q: 7. By how many stops of light does the circular polarizer decrease exposure?

A: The following unit will effectively reduce your lens aperture by up to 2 full stops.
