My Tokina AT-X 28-70 zooms in the opposite direction from all my Canon made lenses, so perhaps they have changed their design.
And my Tokina 11-16 zooms in the opposite direction from my Canon zoom, so any 'design change' is not recent.
LENS DIRECTIONALITY: I just took inventory of different lenses which I have for different format cameras, and have color coded same-behavior lens brands:
Canon 17-->55, 0-->Infinity
Tamron 75<--28, Infinity<--0
Tokina 16<--11, 0-->Infinity
Bronica 45-->90, Infinity<--0
Olympus 35-->70, 0-->Infinity
and supplementing my lenses with those seen in lens tests...
Nikon 35<--16, Infinity<--0
Sony 200<--70, 0-->Infinity
Sigma 24-->70, 0-->Infinity
Pentax 70<--24, Infinity<--0
So you can see the Tokina is consistent with Canon for focus direction, but NOT for zoom! It matches Sony for directionality of controls.
