The 12-28mm f/4.0 AT-X Pro APS-C Lens for Canon from Tokina is a wide-angle to a standard length zoom lens with a maximum aperture of f/4.0. This compact lens features a one-touch AF/MF clutch operation to switch back and forth between auto and manual focus, for manual focus slide the focus ring back and for autofocus allow to the ring to rest in the forward position. The use of SD glass (ultra-low dispersion glass), which emulate fluorite glass in performance, aims to eliminate chromatic aberration and aspherical lens elements in both the front and rear lens groups correct distortion and also helps to minimize aberrations for sharp imaging throughout the zoom range. A GMR (magnetic precision) sensor offers fast, accurate autofocus and the SD-M (Silent Drive-Module) means that the AF motor is virtually silent, which is important when shooting HD video.
