With a focal length of 20mm and F1.4 aperture, this lens delivers outstanding large-aperture brightness and bokeh, delivering unprecedented visual experiences. This lens is ideal not only for such ultra-wide-angle subjects as landscapes and starry skies, but also for snapshots in low light, indoor photography, portraits with a natural bokeh effect, and much more. Designed for ultra-high-megapixel digital cameras, this high-performance lens delivers outstanding resolution and high-clarity image quality even at a wide-open aperture. The Hyper Sonic Motor (HSM) ensures silent, high-speed autofocusing, while the optimised AF algorithm helps realise even smoother AF performance. At any time during AF, users may access MF simply by rotating the focus ring.
This feature makes faster focus adjustment possible since there is no need to use the AF/MF focus mode switch. Also, the optional SIGMA USB DOCK allows the user to set the lens to a conventional full-time manual focus override. With only a few minor exceptions, all of SIGMA's manufacturing, including moulds and parts, takes place under a single integrated production system in Japan. We are now one of the very few manufacturers whose products are truly made in Japan. The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
