Ahh, ok, that makes sense Roman. Now, do you have a preference as to which maker of filter you use? I can certainly see the added benefit, since I do quite a bit of water images.
Thanks!
Take the money you save on buying multipul filters and get the best you can. I like Heliopan and B+W brands. They can be a bit spendy, but when you consider your putting another peice of glass on your lens the lens designer never intended, the extra cost will go a long way to not become the weakest link in your lenses quality.
