Rent NowSigma 18-50mm f/2.8 DC DN Contemporary Lens for Canon RF
Ultra-Compact Fast Standard Zoom Constant f/2.8 Aperture, Stepping Motor AF & Macro-Style Close Focusing (Includes Hood)
The Sigma 18-50mm f/2.8 DC DN Contemporary is an exceptionally small, lightweight, and bright standard zoom lens designed for crop-sensor (APS-C) Canon RF-mount mirrorless cameras. Delivering a versatile 35mm-equivalent focal range of 29-80mm alongside a bright, constant f/2.8 maximum aperture, this lens excels across a wide variety of photo and video applications—including landscapes, portraiture, street documentary, architecture, and events. Its constant f/2.8 aperture ensures consistent low-light performance throughout the zoom range while enabling precise control over depth of field.
Constructed for outstanding image quality without unnecessary bulk, the optical design features three high-precision glass-molded aspherical elements and a Special Low Dispersion (SLD) element to minimize chromatic aberrations, color fringing, and geometric distortion. A Super Multi-Layer Coating suppresses flare and ghosting, fully supporting in-camera aberration corrections for maximum clarity. Powered by a high-speed, nearly silent stepping motor, the lens provides smooth, accurate autofocus ideal for video recording and fast-moving subjects. A close minimum focusing distance of 4.8 inches enables macro-style close-up shooting, complemented by a rounded 7-blade diaphragm for smooth, pleasing background blur.
This lens package includes the dedicated lens hood.
