The 7-14mm zoom range delivers a 180-190 degree field of view with f/2.8-3.5 aperture, using 5 ED and 2 aspherical elements for edge-to-edge sharpness on full-frame RF bodies. Weather sealing and STM autofocus make it a durable, fast-focusing option for extreme wide-angle work in challenging conditions. This lens is best for portrait and street photographers who want a distinct, distorted perspective rather than traditional rectilinear rendering.
