Sigma 18-50mm f/2.8 DC DN Contemporary Lens for Canon RF

The Sigma 18–50mm f/2.8 DC DN Contemporary Lens for Canon RF is a compact, lightweight standard zoom designed for APS-C mirrorless cameras, offering outstanding versatility for both photo and video. Covering a 29–80mm full-frame–equivalent focal range, it’s well suited for landscapes, portraits, street photography, architecture, events, and everyday shooting. A constant f/2.8 maximum aperture throughout the zoom range provides consistent exposure and excellent low-light performance without adding bulk.

The optical design incorporates three high-precision glass-molded aspherical elements and a special low-dispersion element, minimizing aberrations while keeping the lens small and lightweight. Fast, quiet autofocus is driven by a stepping motor, making it ideal for video capture and photographing fast-moving subjects such as children or pets. With a close 4.8" minimum focusing distance for macro-style shots and a rounded seven-blade diaphragm for smooth, pleasing bokeh, this lens is a reliable, all-purpose workhorse for Canon RF APS-C shooters.

Features

• Standard zoom lens is designed for APS-C-format Canon RF-mount cameras and provides a 35mm equivalent focal length range of 29-80mm.
• Constant f/2.8 maximum aperture is well-suited for working in low-light conditions and provides greater control over the focus position when using shallow depth of field techniques.
• Three high-precision glass-molded aspherical elements are used to help limit distortion and spherical aberrations and contribute to greater overall sharpness and accurate rendering.
• Special Low Dispersion (SLD) element reduces chromatic aberrations and color fringing.
• Super Multi-Layer Coating minimizes flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions.
• In-camera aberration correction further eliminates optical imperfections such as distortion and vignetting.
• Stepping motor with nearly silent autofocus that makes it perfectly suited to a range of photographic applications, including shooting in quiet environments, recording videos, and capturing fast-moving subjects.
• Minimum focusing distance of 4.8" and a 1:2.8 maximum magnification ratio benefits working with close-up subjects.
• Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
