I use this filter to protect the lens of my camera! There is no impact on the photos I took, at least I did not notice, this is exactly what I wanted. Otherwise, hop, I take it off during the session of shots. Associated with polarizing filter HOYA CIR-PL on a EFS 18-55 IS lens, the assembly does not cause vignetting on my 600D. I have not tried it on other goal, but if you want me to buy one for me to do a test, do not hesitate! ;-)
Not doing video, I can nothing to say on the use of UV filter with this function.
