Not doing apples-to-apples comparisons with focal length and entrance pupil often adds confusion to the \"filter-or-not\" debates --- one person sees degradation on their fast telephoto (using a high-$ filter), which another disputes because their wide-angle slow zoom works with the cheapest window-glass filter. The level of filter quality necessary to avoid noticeable compromise in image quality might vary by an order of magnitude or two based on the lens (length, speed, intrinsic sharpness, filter reflection interactions).
I did not see this on my 400/5.6 telephoto with a B+W filter but it isn\'t that fast of a lens either. I do plan on getting the Sigma 120-300 zoom this year with the front threads for a 105 filter and it will interesting if this has any issues.
