The Sigma 28-45mm f/1.8 DG DN Art is a constant-aperture zoom lens for full-frame cameras with a Sony E mount. The f/1.8 aperture is maintained throughout the zoom range, while the optical construction comprises 18 elements in 15 groups, including 3 aspherical elements and 5 Special Low Dispersion elements. The 11-blade rounded diaphragm helps create smooth bokeh.
The internal zoom design keeps the lens’s overall length constant during use, while its design minimizes focus breathing as the focal length changes. The linear actuator autofocus system operates quietly and accurately. The lens has a minimum focusing distance of 11.9 inches and a maximum magnification ratio of 1:4 at its longest focal length.
