LOL @ Tokina. It is the same lens construction as the AT-X 11-16mm f2.8 DX II, which has the same lens construction as the AT-X 11-16mm f2.8 DX. So, they dropped the Nikon moniker "DX" for "APS-C", now calling it "CF" (crop format?) and adding an "i" for nonsense sake. How Pentax of them.
And the clutch is still there too (though I thought the construction was altered somewhat, but I might've been mistaken).
