A large-aperture ultra-wide-angle zoom lens with excellent imaging power. This compact lens effectively corrects aberrations, achieving high sharpness across the entire frame and a bright f/2.8 aperture. Enjoy the powerful perspective and powerful image quality unique to ultra-wide-angle lenses, from wide open aperture to any aperture setting. This lens incorporates multiple aspherical and special-low-dispersion glass elements, which require advanced manufacturing techniques. By using an aspherical lens with a large refractive index and thickness deviation for the first element, the lens construction is reduced, achieving high resolution while maintaining a compact and lightweight overall lens. A minimum focusing distance of 11.6cm and a maximum magnification ratio of 1:4 are achieved at the wide-angle end. Its excellent close-up shooting capabilities enable a wide range of creative possibilities, including close-up photography that takes advantage of the ultra-wide-angle angle. A compact and lightweight body that's been stripped down to the bare minimum: At just 62.0mm long, 72.2mm in diameter, and weighing just 260g, it's the world's smallest and lightest* lens. It's perfect for carrying around, or even setting up with a gimbal, making the most of the mobility of an APS-C mirrorless camera in any situation. *This is an AF-compatible, F2.8 constant zoom lens for APS-C mirrorless cameras (as of October 2023, according to Sigma). *These figures are for the L-mount.
Newly developed push-on petal-shaped hood: The included hood is a newly developed push-on petal-shaped hood. Unlike the conventional bayonet-type hood, which requires a twist, this hood attaches easily and securely. This new design also contributes to the hood's smaller diameter.
When combined with the compact, lightweight, and high-performance SIGMA 18-50mm F2.8 DC DN | Contemporary, a constant F2.8 zoom lens series, you can cover a wide angle of view (35mm equivalent: 15-75mm) with a bright F2.8 aperture. The combined weight of both compact and lightweight lenses is just 550g*. *These figures are for the L-mount.
Simple dust-proof and splash-proof construction: A rubber seal is used on the mount to prevent dust and water from entering through the connection with the camera.
Easily create high-quality videos with this compact, lightweight, and bright zoom lens, ideal for video shooting. Its high mobility and imaging power assist in high-quality video production. Taking advantage of the characteristics of an ultra-wide-angle lens with a short minimum focusing distance, you can easily capture scenes that include the background, even when taking handheld selfies for vlogging and other purposes.
Designed to suppress focus breathing The lens is designed to suppress focus breathing. Since there is minimal change in the angle of view due to focus shifts, natural focus shifts can be achieved in video shooting.
Stepping motor The AF actuator uses a stepping motor. The fast and quiet AF allows for comfortable shooting without worrying about noise. [Accessories] - Push-on flower-shaped hood (LH706-02) - Front cap (LCF-67mm III) - Rear cap (LCR II) ■ Specifications ■
