Sigma 12-24mm f/4.5-5.6 II EX DG HSM, Canon retail EF Fit I keep a couple of pieces of Scotch tape on the pedal lens hood to increase the friction with the lens cap (prevents it from falling off if the lens is pointed down). Glass is clean with no scratches that I can see, and no dust that I can see inside. Lens is stuck in autofocus mode (AF/MF switch cable broke). The Sigma 12-24mm F4.5-5.6 II DG HSM is a premium wide angle zoom lens designed for full frame DSLRs but will work with APS-C cameras with an effective increase in focal length. Four FLD glass elements (with performance equal to fluorite) and one SLD element (Special Low Dispersion) ensure premium image quality from edge to edge. Three glass mold elements and one hybrid aspherical lens allow for a lightweight and durable construction while the super multi-layer coating reduces flare and ghosting. The Hyper Sonic Motor (HSM) ensures quick, quiet and accurate autofocusing. https://www.sigmaphoto.com/12-24mm-f4-5-5-6-dg-hsm-ii.
