Out of Canon's 10-22, Sigma's 10-20, Tokinas' 12 -24..
I like 11-16.

BUT will it auto focus on Canon 550D? Canon 550D doesn't have body focusing motor.


on the Tokina website it says "*** Will not AF when used on Nikon D40 SLR camera body. "... so your telling me it's gonna auto focus on D60?..

Does Tokina even make built in AF lenses?... 0.0

The AT-X 116 PRO DX supports the "One Touch Focus Clutch Mechanism"which:
    allows the photographer to switch between AF and MF simply by snapping the focus ring forward for AF and back toward the camera to focus manually. There is no need to change the AF-MF switch on Nikon cameras** and there is no second AF/MF switch on the lens for Canon, everything is accomplished by the focus ring.

As far as I know, any manufacturer making a current lens for Canon mount will AF on Canon bodies. Canon doesn't have the distinction between certain lower end models not being able to AF with certain lenses like Nikon does...Nikon mount lenses must specify whether they are compatible with the lower end Nikon models without focus motors.

As for UWA lenses, the Tokina 11-16 is usually the best reviewed of that bunch. I've been very happy with the Tamron 10-24, which is the next fastest, along with the much more expensive Sigma 10-20 F3.5. The Tokina 12-24 I don't have much knowledge of.
