THE PERFECT PRIME FOR LANDSCAPES, TRAVEL AND ASTRO
This full-frame, ultra-wide-angle prime for mirrorless cameras is perfect for night sky photography, landscapes, interiors, weddings, travel and architecture. Its ultra-wide aperture of F1.4 ensures very fast shutter speeds in lower light conditions, as well as a very shallow depth-of-field for pronounced subject separation.
The lens comes with a raft of pro-level features that includes an aperture ring with de-click and lock switches, an AFL button, a lockable lens hood, a rear filter holder, a Lens Heater Retainer and a manual focus lock feature. The optical design includes two SLD and three aspherical elements, one of which is the largest double-sided aspherical glass element in Sigma’s history. These advanced optics ensure very minimal chromatic aberration, sagittal coma flare and image distortion, giving highly-detailed images with exceptional sharpness and accuracy from the centre to the periphery of the frame.
