i frequently stack B+W neutral density filters with a Hoya HMC circular polarizer on my DA 16-45/4 at the wide end with no vignetting. on occasion, i have stacked three filters on the DA 16-45/4. none of my filters are the wide angle versions. none of my wide lenses that take filters are wide enough to vignette with only one filter. i haven't stacked two filters on the DA 14/2.8 yet to try.
