Tokina 12-24mm features non-rotating 77mm filter threads which mean special effect filters will not change when the lens' focus is changed. This fact is very useful while using circular polarising filters. Hoya Pro 1 digital filters are recommended to be used with Tokina Canon EOS-fit 12mm-24mm Lens.

Built in fast internal focusing with Tokina's One-Touch focus clutch mechanism allows the lens to focus faster and switching between auto and manual focus is as easy as snapping the focus ring back and forth.
Tokina Canon-Fit 12mm-24mm  uses 2 sharp-cut aspherical lens elements which accurately correct aspherical aberration usually associated with ultra-wide angle lenses.
The bight f4.0 constant aperture allows plenty of light to enter the camera for shooting in a wide variety of photographic situations especially in low light photography.
Tokina used chrome plated brass mount plate and all-metal zoom unit for this lens. This can stand up to regular use while advanced polycarbonate outer lens barrels reduce the weight of the lens, making it a easy to carry.
