I have been going crazy looking and searching all i find is "Vignette" "Vignette". The lens is 82mm filter thread. I really need a setup that does not vignette not even a mm. Id really like to hear what people are using, most here is about the 16-35mm but its the same thread, im guessing filter holder and mm of filter 100 105 150 etc.
p.s id love some links but that is maybe pushing it... heheh
