Tokina 24-70mm F2.8 AT-X PRO FX Lens
- Canon Fit The Tokina AT-X 24-70mm F2.8 PRO FX lens gives photographers with full frame Canon & Nikon camera bodies a 24mm wide-angle to 70mm moderate telephoto lens with a fast F2.8 aperture at an affordable price. The new groundbreaking proprietary optical design uses three precision molded all-glass aspherical lens elements to achieve excellent contrast, sharpness, & corrects for spherical aberrations. One of these elements is very special & difficult to manufacture. G09, is made from Super-Low Dispersion (SD) glass & is a large sized aspherical element. These lens elements also yield even illumination across the whole image sensor. The Tokina 24-70MM lens also uses three SD (super-low Dispersion, “FK01” & FK03”) glass elements in the rear groups to control chromatic aberrations. All these specialized lens elements work in consort to yield maximum resolution to match the 50-megapixel DSLR cameras entering the market. The fast constant F2.8 aperture makes viewing & auto focusing possible in very low light situations while keeping some flexibility for setting the shutter speed. In addition to excellent optics, the lens incorporates a fast moving SDM (Silent Drive-Module) motor to greatly reduce AF noise making it one of Tokina’s quickest & quietest auto-focusing lenses to date. Tokina’s exclusive One-touch Focus Clutch Mechanism allows the photographer to switch between AF & MF simply by snapping the focus ring forward for AF & back toward the lens mount for manual focusing. The lens is also designed to stand up to the rigors of daily use by photographers in a wide variety of shooting conditions & environments.
