I don't know if this should be posted here or in the "what camera should I buy?" section. But I would like to know what some recommendations are for good filter brands or makes? I am looking at purchasing the Canon EOS 50D, with 2 L series lenses (EF 24-70mm f/2.8L USM and EF 70-200mm f/2.8L IS USM). I know these are top notch lenses but if I put a poor quality filter on the end won't that defeat the purpose of buying such good lenses?

So what do you recommend for good, distortion free, and good image filters? What price range am I looking at and what brand(s) should I stick to? Any other caveats I should be aware of when purchasing filters?

I was going to get a standard UV Filter just to protect the lenses, and then a few filters that would be used marginally, such as contrast filters, polarized filter, and some color filters. I have not shot on DSLR before but I have shot on SLR Film so if a lot of the benefits of these other filters are not really needed on DSLR let me know. Thanks for the input.
