Sigma 15mm f/1.4 DC Contemporary Lens For Canon RF

Product Description Ultra-Fast, Ultra-Wide, Ultra-Compact An ultra-wide with an especially portable design, the Sigma 15mm f/1.4 DC Contemporary Lens For Canon RF is a strikingly compact and fast prime lens with a huge field of view. Ideal for landscapes, interiors, architecture, and astrophotography applications, this is a maximalist lens with a minimalist form factor. Speed and Sharpness Designed for use with APS-C-format cameras, this lens offers a 24mm-equivalent focal length. Ultra-wide field of view pairs with a fast f/1.4 maximum aperture to suit working in low-light conditions and for controlling depth of field. Optical design includes FLD and SLD glass elements to reduce chromatic aberrations and achieve high color accuracy. Three double-sided aspherical elements control distortion and spherical aberrations, as well as help to promote high sharpness and reduce the overall size and weight of the lens. Optical design prioritizes edge-to-edge sharpness and reducing sagittal coma flares, even when shooting wide open. Lens flare and surface reflections are also well-controlled to suit working in bright, high-contrast environments. Rounded 9-blade diaphragm contributes a smooth, rounded bokeh quality.

Suitable for both photo and video recording, the compact, lightweight, and balanced design makes this an ideal option for gimbal-based shooting and vlogging applications. Stepping motor delivers quick, quiet, and accurate autofocus performance. Additionally, focus breathing is well-controlled to maintain the field of view while pulling focus. Durable Design and Handling Dust- and splash-resistant design complements working in outdoor and inclement conditions. Additionally, a water- and oil-repellent coating has been applied to the front lens element to resist the elements and make it easier to clean. Control ring can be customized to control various exposure settings, including aperture, exposure compensation, and more. Included petal-shaped lens hood reduces lens flare and protects against accidental bumps. Well-matched to other Sigma f/1.4 DC lenses to create a compact system of fast, consistent prime lenses spanning a wide range of focal lengths.
