RF ultra wide-angle zoom lens for the EOS R series cameras. Outstanding ultra-wide zoom coverage for stills and video with full-frame EOS R series cameras; equivalent to approx. 24–48mm coverage when used on cameras with APS-C size image sensors. Excellent image quality: highlights include two UD (Ultra-low Dispersion) glass elements, one aspheric element, and Canon SSC (Super Spectra Coating) to minimize ghosting and flare. Optical image stabilization — up to 5.0 stops* of shake correction. Up to 7.0 stops of shake correction when paired with EOS R series cameras featuring In-Body Image Stabilizer (IBIS). Minimum focus distance of approx. 11 In./0.28m (5.1 In./0.13m in manual focus at 15mm zoom position.)
