10-18mm f/2.8 DC DN Contemporary (Canon-RF)

The Sigma 10-18mm f/2.8 DC DN Contemporary Lens is a compact ultra-wide-angle zoom designed for Canon RF mount cameras, offering a 16-29mm full-frame equivalent focal range with a constant f/2.8 maximum aperture throughout its range. The optical design of 13 elements in 10 groups delivers strong low-light performance and produces smooth bokeh through its rounded 7-blade diaphragm. At just 9.5 ounces and 2.4 inches long, this lens maintains portability without compromising optical quality, making it well-suited for travel and video work.

The lens features internal autofocus with a minimum focusing distance of 4.6 inches and a 1:4 magnification ratio for close-focusing capabilities. The dust and splash-resistant mount provides durability in variable conditions, while the included petal-style lens hood maintains the compact design. Adobe lens correction profiles are compatible with this lens to address distortion and vignetting in post-processing.
