Sigma 17-40mm f/1.8 DC Art Lens Canon RF
A constant-aperture wide-to-standard zoom for Canon RF-mount APS-C cameras, the Sigma 17-40mm f/1.8 DC | Art holds a bright f/1.8 right across its 17-40mm range (roughly 27-64mm full-frame equivalent) — a do-everything lens for landscapes, interiors, street, portraits and video. Its premium optical design of 17 elements in 11 groups (4 aspherical and 4 SLD elements) controls aberrations for edge-to-edge sharpness, while an 11-blade aperture renders smooth bokeh. It focuses as close as 0.28m (up to 0.21x magnification) and carries a 67mm filter thread.
