The circular distortion occurs at the zoom's maximum focal length. I think it might occur even without a shallow depth of field -- i.e. no bokeh. I don't have a photo illustrating that because I bought the lens for close-ups (70-200). Anyway, when I first brought it up on this list, the consensus was that swirlies was a different and separate effect than just bad bokeh -- so I will go with the list's wisdom.
