My Tokina 11-16mm f/2.8 AT-X 116 is one such example, my Sigma 50-150mm f/2.8 DC OS HSM is another. I think it should be pointed out that Tokina lenses often come in two varieties as well: those that come with an internal auto-focus motor and those that come without an internal auto-focus motor. If that feature matters to you be sure you know which variety you're getting. I think the "II" designation indicates the presence of a built-in motor, but I'm not sure that holds true across their product line.....</blockquote>
