What does or doesn't vignette depends on the field of view of a particular lens and format along with the design of the lens barrel and filter retaining thread mount, and the thickness and design of a particular filter mount. Without knowing all the particulars it would be impossible to say for sure what does or doesn't vignette without testing. Even then, testing is the best way to be sure...
