Sigma 20mm f 1.4 DG HSM Art Lens
- Canon Fit With a focal length of 20mm & F1.4 aperture, this lens delivers outstanding large-aperture brightness & bokeh, delivering unprecedented visual experiences. Allowing the photographer to leverage the perspective provided by the wide-angle & the shallow depth of field provided by the large aperture, this lens is ideal not only for such ultra-wide-angle subjects as landscapes & starry skies, but also for snapshots in low light, indoor photography, portraits with a natural bokeh effect, & much more.
Features: World’s first* 20mm F1.4 lens
- thanks to advanced large-diameter aspherical lens manufacturing technologies: To offer an ultra-wide-angle 20mm focal length & F1.4 brightness at wide-open aperture, this lens incorporates a large double aspherical lens 59mm in diameter. Lenses of this type had been considered extremely difficult to manufacture, but SIGMA took on the challenge to realise an F1.4 ultra-wide-angle lens that fulfils the strict performance requirements of the SIGMA Art line. What made this breakthrough possible were SIGMA’s advanced manufacturing technologies, which the company has developed over time by producing a wide range of ultra-wide-angle & large-aperture lenses. For example, milestone lenses such as SIGMA 12-24mm F4.5-5.6 EX DG ASPHERICAL HSM, SIGMA 8-16mm F4.5-5.6 DC HSM, & SIGMA 18-35mm F1.8 DC HSM Art were completely original products that helped SIGMA develop outstanding design & production know-how & its current high-precision, high-efficiency production system. In turn, these advances made possible the new SIGMA 20mm F1.4 DG HSM Art. Moreover, SIGMA’s advanced optical design minimizes distortion, transverse chromatic aberration, sagittal coma flare, & the reduction of brightness toward the edges of the image. Delivering top performance even at wide-open aperture, this lens can be considered the culmination of SIGMA’s Art line. * Among interchangeable lenses for digital cameras with 35mm full-frame image sensors. Top-level performance for the ultra-high-megapixel era: At the dawn of the film camera, there was very little high-sensitivity film, & bright lenses that worked well in low-light conditions came to be known as “high-speed lenses.” These lenses are ideal for shooting indoors, in the evening, under cloudy skies, or in any low-light situation. Since the SIGMA 20mm F1.4 DG HSM Art provides the benefits of an ultra-wide angle lens with minimal distortion, it is ideal for photographing landscapes, starry skies, & architecture. In addition to capturing wide-angle shots with the whole scene in focus, the photographer can leverage wide-open aperture to take snapshots with the subject in focus & the background blurred with an attractive bokeh effect. Designed for ultra-high-megapixel digital cameras, this high-performance lens delivers outstanding resolution & high-clarity image quality even at wide-open aperture. Art line delivers high-level artistic expression: SIGMA is organising all its interchangeable lenses into three product lines: Contemporary, Art, & Sports, each with a distinctive concept. Designed with a focus on sophisticated optical performance & abundant expressive power, our Art line lenses deliver high-level artistic expression. Offering astonishing rendering performance that meets the highest standard, they are perfect for landscapes, portraits, still-lifes, close-ups, & casual snaps. They are made for the kind of photography that unleashes the inner artist. A powerful ally in every genre of photography, SIGMA’s Art line lenses excel both in the studio for formal works & outdoors for impressive shots of architecture, starry skies, & many other scenes. Sigma USB (Universal Serial Bus) Dok for SIGMA GLOBAL VISION lenses (optional): With the optional SIGMA USB (Universal Serial Bus) DOCK, you can update your lens firmware & adjust the focus position & other settings. Simply connect the lens to the SIGMA USB (Universal Serial Bus) DOCK & the dock to a computer to use the dedicated SIGMA Optimization Pro software & perform various types of customization & adjustment. Hyper Sonic Motor ensures high AF speed: 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 (Universal Serial Bus) DOCK allows the user to set the lens to conventional full-time manual focus override.
