The Sigma 30mm f1.4 lens creates sharp images with sharp contrast, from 40cm minimum focusing distance. This lens was manufactured to match the APS-C size image sensors of digital SLR cameras and the two SLD glass elements in this lens are great at compensating for magnification chromatic aberration. The glass mold aspherical lens reduces color aberration and provides good-quality image results. The lens’s large maximum aperture of F1.4 is ideal for taking landscape photography, portraiture and indoor shooting. The Sigma 30mm lens includes a 62mm filter mount and is brought out with numerous different camera mounts. This lens has not been manufactured to take long distance photographs though. You will appreciate the fairly light-weight construction of the lens, as well as the ease with which you can move from automatic focus, into manual mode, without having to flip any switches. Owners receive a one-year warranty with their new Sigma 30mm lens.
