Tokina AT-X 24-70mm f/2.8 Pro FX - unknown Mount

The Tokina AT-X 24-70mm f/2.8 Pro FX is a standard zoom lens for full-frame DSLRs, designed to compete with flagship professional optics. It features a complex optical arrangement including three aspherical and three extra-low dispersion elements to minimise aberrations. The constant f/2.8 aperture provides consistent exposure and depth-of-field control throughout the zoom range. It uses an SD-M autofocus motor for improved speed and reduced noise. Used buyers should check for zoom creep, though the build quality is generally very high. Test the One-Touch Focus Clutch for smooth movement between AF and MF positions. SDS ensures the lens is optically centred and that the autofocus is consistent at both ends of the zoom range. Inspect the rubber zoom and focus rings for any signs of loosening or perishing.
