My experience is: 90mm, no vignetting even with 2 filters + hood; 45mm, no vignetting with one filter + hood; 28mm, no vignetting with a filter and no vignetting with a hood-but definite vignetting when hood and filter are combined. The 21mm does not vignet with a filter. I have not used a hood with this lens. All filters used were rather thick, standard Tiffens. By the way, I cannot tell that the Tiffen brand degrades my picture quality in any way.
