Tokina 12-28mm f/4.0 AT-X PRO APS-C Lens for Canon EF

Tokina is a brand name that is loved and trusted within the photography world. Tokina has an optical manufacturing tradition that dates back over 60 years and they specialize in high-quality lenses for today's digital single lens reflex (DSLR) cameras. This brand is known for specialty glass and lenses like the ATX PRO series. The PRO series is packed full of amazing features such as the new AF Mechanism and the newly designed body but still gives you the traditional reliability expected from Tokina.

Wide Zoom Range

The Tokina AT-X 12-28mm f/4 lens has a super-wide to standard zoom range while maintaining a constant fast f/4.0 aperture. Because of the wide angle coverage, this makes it a very versatile lens for different photo applications such as scenery, street scenes photography and event coverage. The lens is designed for DSLR cameras with APS-C (DX) sized sensors.

New Optical Design

A new optical design using aspherical elements and super-low dispersion glass matches even the highest mega-pixel DX sensors cameras available today. One aspherical lens element is positioned in the front group. This together with another precision molded glass aspherical lens element placed in the rear group ideally focuses marginal light rays and maintains sharpness at the edges while also correcting distortion. The use of two different SD (Super-low Dispersion) glass elements, type FK01 and FK03, corrects chromatic aberration. The combination of all these specialized elements in the optical design yield excellent sharpness and color. The Tokina AT-X 12-28mm f/4 compact design makes the lens easy to carry and handle.

Auto Focus Mechanism

The new AF “GMR magnetic precision” control sensor is capable of extremely fast auto-focusing. Tokina placed the new sensor closer to the drive unit in the lens for faster communication between the controller and AF motor. This combined with the motor's high-precision focus control yields faster, more accurate auto-focus. Additionally, a brand new “SD-M” (Silent Drive-Module) has greatly lowered the sounds emitted by the auto focus drive system allowing for much quieter AF. Both Canon and Nikon mounts have a built-in AF motor to make them auto-focus compatible with all current camera bodies. This quieter motor makes using this lens for video even better!
