Sigma Adds Super Wide and Fast 20mm f/1.4 Art Lens

Sigma make some really awesome lenses and compared to Canon L series and Zeiss lenses tend to be more affordable. Low-budget filmmakers embraced their Art line of primes lenses especially the 35mm 1.4 and the 50mm 1.4 Art and their award-winning Sigma 18-35mm f1.8 DC HSM zoom lens for APS-C sensors that is frequently used on Super 35 sensor cameras like the C100/C300 and Sony FS7. And now, Sigma is expanding their Art lens line-up by introducing – the new SIGMA 20mm F1.4 DG HSM Art lens, the World’s first F1.4 ultra-wide-angle lens with full-frame 35mm (36 x 24mm) coverage.

With a focal length of 20mm and F1.4 aperture, this lens delivers outstanding large-aperture brightness and “bokeh”, delivering unprecedented visual experiences. However the true beauty if this lens is it’s high adaptability to other cameras – not just Canon and Nikon DSLR’s. Sony FS7 shooters can use a Metabones Speed Booster and benefit from the staggering f/1.0 aperture, pretty much the widest you can get these days. Sony A7s and A7rII users can also adapt this lens via a compatible Metabones Smart Adapter.

…Allowing the photographer to leverage the perspective provided by the wide -angle and the shallow depth of field provided by the large aperture, 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.

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 and 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, and SIGMA 18-35mm F1.8 DC HSM Art were completely original products that helped SIGMA develop outstanding design and production know-how and 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, and 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.

Lens Cap LC907-02 (optional purchase): Matching the high-quality finish of the lens exterior, the optionally available metal lens cap will go on sale simultaneously with the lens. Featuring materials identical to those of the lens barrel, this metal lens cap establishes a new level of unity within SIGMA’s new lens lines.

The new Sigma 20mm f/1.4 lens will be available in the following mounts: SIGMA, Nikon F/G, and Canon EF.  Accessories included in the box include – Lens Case and Cover Lens Cap (LC907-01).

The new Sigma 20mm f1.4 Art lens is expected to start shipping at the beginning of November, 2015 and retail in the UK for £849.99 (inc. VAT List) or $899 in the US.
