I read all the complaints about filters degrading image quality. I think that may be true in two cases -- cheap, low quality filters and when the filter gets excessively dirty.
Then I remove and gently clean the filter. While I am sure there are technical means to identify a small degradation of image quality when using filters, I have never actually seen this in my photographs. There are far more reasons for poor image quality than filters. AND -- filters are good protection for the end of your lens that is exposed the whole time you are using it. If your targets are test charts and brick walls, I guess you can discard the filters. But if you shoot in the real world, where there is dust and other stuff in the air I recommend high quality filters: Nikon, etc. They are cheap insurance for a $2,000 lens.
