Sigma 15mm f/1.4 DC Contemporary Lens (Canon RF)

Sigma 15mm f/1.4 DC Contemporary Lens
Ultra-Compact Wide-Angle Prime – Fast f/1.4 Aperture, Stepping AF Motor & Weather-Sealed Build

The Sigma 15mm f/1.4 DC Contemporary is an ultra-wide, high-speed prime lens designed for APS-C mirrorless camera systems. Delivering a 22.5mm full-frame equivalent focal length, this compact optic combines an expansive field of view with an ultra-fast f/1.4 maximum aperture. Well-suited for landscapes, interiors, architecture, astrophotography, and vlogging, it provides strong low-light performance and shallow depth-of-field control in a lightweight package.

Engineered to prioritize edge-to-edge sharpness and control sagittal coma flare wide open, the optical layout incorporates FLD, SLD, and three double-sided aspherical elements to suppress chromatic aberrations, distortion, and optical artifacts. Multi-layer coatings suppress flare and ghosting under high-contrast lighting. Powered by a quiet stepping motor with minimal focus breathing, the lens delivers fast AF tracking for stills and video. Measuring just 2.6 inches in length and weighing approximately 8 oz—30% shorter and 50% lighter than the 16mm f/1.4 DC Contemporary—the chassis features a tactile aperture ring with an ‘A’ position, a water- and oil-repellent front coating, environmental weather sealing, and a petal-shaped lens hood.
