Slightly vignettes at 17mm only slightly and stops around 18 or 19 and also depends on your focus, iris at 17mm. And the vignette is usually just out side 16x9 at full 5k and almost is not there at all at 5k 2:1,,,,I have one of these and would not trade it. Its a work horse when you need a short zoom.
