Sigma 20 MM F1.4 DG HSM ART Lens | Camera Warehouse Australia

In a world that puts a premium in instant production, faster is better. This applies to anything from the supply chain to emergency response. The same thing can be said in photography. With faster lenses come more precise image detail which result in better photos. That being said, Sigma has developed the 20 mm F1.4 DG HSM | Art lens which is the fastest 20 mm Ultra Wide Angle Lens in the world.


Its rapid responses are made possible by its Hyper Sonic Motor that enables silent but quick auto focus action. Consequently, this lens is also the first F1.4 Ultra Wide Angle Lens for Full Frame DSLRs in the world. Likewise, the internal parts of this new Sigma lens are made of metal and Thermally Stable Composite which makes it 70 per cent more elastic than polycarbonates with glass. This makes its parts maintain its performance despite thermal expansion during hot or humid temperatures.


The same parts also reduce distortion, chromatic aberration, and brightness in the frame’s edges too. With this feature, Sigma ART lenses, particularly the 20mm F1.4 DG HSM, capture astonishing pictures whether it is used for landscape, portraits, close-ups, and casual photos. If it is bokeh and out-of-focus effects that you fancy, you will enjoy the nine-blade rounded diaphragm and wide open aperture as well.


In the retail package, the Sigma 20 mm F1.4 DG HSM | Art lens comes with a lens cap. There’s also an optional USB Dock that allows firmware updates and focus adjustments. This dock can also be used to access Sigma’s Optimization Pro software. This Sigma Ultra Wide Angle lens will be available by November although there is still no definite release date yet. Aside from Sigma full-frame cameras, the same lens is compatible with Canon and Nikon full-frames as well. You may also get more details about this product here.
