Sigma are known for producing some really nice lenses at quite affordable prices. But they really struck gold with their Art line of primes lenses and especially their award-winning 18-35mm f1.8 DC HSM zoom lense for APS-C sensors.
And now, the company 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 (36x24mm) coverage.
SIGMA has extensive experience in leveraging its advanced design capabilities and leading-edge technologies to craft large-aperture prime lenses that bring out the full potential of ultra-high-megapixel DSLRs. As its latest achievement in this category, SIGMA has created an ultra-wide-angle lens with F1.4 brightness.
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.
