Sigma AF 14mm f/1.8 DG HSM Art Lens for Sigma SA

Overview

The Sigma AF 14mm f/1.8 DG HSM Art Lens is specially designed for astrophotography. This lens can be used with Sigma cameras that have an SA mount. The lens has 16 elements, including 3 FLD, 4 SLD, and 4 aspherical elements, arranged in 11 groups. This optical construction reduces color fringing along with chromatic and spherical aberrations in images. The super multi-layer coating on the lens reduces ghosting and delivers accurate, vivid colors. A smooth bokeh quality is offered by the nine-blade diaphragm. The Hyper Sonic AF motor helps in quickly focusing on an object without making much noise. Also, you may use the manual-focus override option to click photos of objects as close as 10.63 inches. This Sigma lens has a composite-material body that allows you to use it in varied temperatures and environments.
