The world’s first f/1.8 prime lens at the 14mm focal length, the Sigma 14mm f/1.8 DG HSM Art lens for Leica/Panasonic L-Mount features an industry-leading 80mm-diameter precision-molded glass element, helping generate images with virtually no distortion, flare or ghosting. Additional optical elements help minimize chromatic aberrations, and the integrated HSM ensures smooth, quiet autofocus. The ultra-wide angle delivers sharp, detailed shots from edge-to-edge, and allows for flexibility in depth-of-field. Get creative A fast, ultra-wide-angle prime lens, the Sigma 14mm f/1.8 DG HSM Art lens is only 5 inches (126mm) long and weighs less than 2.5 pounds (1120g), so it’s easy to take anywhere. The bright f/1.8 maximum aperture is perfect for low-light conditions as well as creativity in depth-of-field, and lends itself well to landscapes and architecture, as well as astrophotography. A Minimum Object Distance (MOD) of 10.6 inches means more detail in close-up shots. Sharp, accurate imagery Three “F” Low-Dispersion (FLD) and four Special Low Dispersion (SLD) elements in the Sigma 14mm f/1.8 DG HSM Art lens work together to help minimize chromatic aberrations and color fringing, increasing color accuracy. Four aspherical elements, including an 80mm-diameter precision-molded glass element, reduce distortion, improving overall image clarity. A Super Multi-Layer coating on the lens elements helps minimize ghosting and flaring, generating greater color contrast and precision tonality. Quick, quiet autofocus The Hyper Sonic Motor (HSM) in the Sigma 14mm f/1.8 DG HSM Art lens provides fast, smooth autofocusing, all while maintaining near-silent performance. Full-time manual focus is easily achieved by rotating the focus ring.
