did this for another thread, but figured I'd share it where more people could find it.
Here it is with the hood on:
then w/o at each whole FL:
11mm
12mm
13mm
14mm
15mm
16mm
15 is close to in the clear, but it's still got black corners, 16 has normal vignetting from a wide open lens (and interestingly, the 5Dii know the lens and corrects for it in camera with it's peripheral whatchamacallit correction).
