The Tokina 12-28mm f/4.0 AT-X Pro Lens is a wide-angle to standard length zoom lens with a maximum aperture of f/4.0. It is compatible with Canon and Nikon cameras and provides a 35mm focal length equivalency of 18-42mm. 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. A newly designed GMR (magnetic precision) AF sensor is mounted close to the AF motor and provides fast, accurate AF. The lens' SD-M (Silent Drive-Module) means that autofocus responds smoothly and silently, which is ideal when shooting HD video.
Tokina has announced the US price for its Tokina 12-28mm f/4.0 AT-X Pro lens. Soon to be available in both Canon and Nikon mounts for APS-C bodies, this lens was announced at the CP+ tradeshow back in January and will replace the company’s existing 12-24mm F4 wideangle zoom for APS-C cameras.
Along with the Tokina AT-X 70-200 F4 PRO FX VCM-S announced at CP+ Show 2013. The Tokina AT-X 12-28mm F4 PRO lens is also announced. This lens is a replacement for the company’s existing 12-24mm F4 wide angle zoom for APS-C cameras. But rather than making the lens wider to match its competitors, Tokina has chosen to extend it further into the ‘normal’ range, to give an 18-42mm equivalent zoom.
