This barrel is large and quite heavy. (To compare, in 2008 we called Canon’s 16–35mm f/2.8L II, which is 12 ounces lighter, “tank-like.”) It’s nicely finished with gold accents and a fixed hood. Unlike most internal-focusing lenses, this Tokina doesn’t offer full-time manual focus. But in use it feels close to that norm, thanks to the smooth-turning MF ring, which doubles as a push/pull-type MF/AF switch. The zoom turn, although even, feels stiff, and the new DC motor makes the AF action fast and very close to silent.
