A few weeks ago I purchased a Digital Rebel XT (body only) and picked up a really sweet Sigma (18-125) lens. I love the combination and I am really starting to get more familiar with it.
I figure that I should probably get a filter (or 2 or 3?). Not only to protect the lens itself but to help tweak my photos. There seem to be a few common ones (UV, polarizing, flourescent). Are there any specific "basic" ones I should make sure to pick up? Do brands really matter that much? I have heard of some brands (like Hoya) but some places sell "house brand" type stuff that is made in Japan as well and is guaranteed, but I don't really know if there is a difference.
I hope we have some photo geeks on here.
