Features:

• 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” and 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 and 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 and quietest auto-focusing lenses to date.
