Sigma 20mm F/1.4 DG HSM Art
Lens for Sigma:
Sigma 20mm F/1.4 DG HSM Art Lens for Sigma belongs to the
Sigma’s Art series of professional lenses with an emphasis on artistic
expression. The lens is suitable to use for sorts, landscapes, portraits, arts,
group shots and general use. For wide angle photography, the 20mm lens and its
circular 9-bladed f/1.4 aperture ensure excellent brightness and blurred
background bokeh effects. The lens minimum focusing distance of 27.69cm allows
capturing wide-angle close-ups from nearly a foot away. With a bright f/1.4
maximum aperture, floating inner focusing system, and Hyper Sonic Motor (HSM)
the lens offers quick and accurate control over the artistic effects achieved by
the lens' high quality elements. The lens works perfectly with auto focus as
well as full time manual cameras, without having to switch camera modes or
change settings but just shifting the switch from AF to MF. The lens Hyper Sonic
Motor (HSM) and floating inner focusing system ensures quick, quiet and precise
auto focusing. The lens Anti-flare super multi layer coatings reduce lens flare,
internal reflections and light scattering that can occur between the surfaces of
its glass elements. This lens incorporates a brass made bayonet mount which has
both high accuracy and durability. A special treatment is applied to the
surface, giving it greater strength and making it highly durable for long-term
use. The
lens incorporates "F" Low Dispersion (FLD) glass elements, which have
performance, equal to that of fluorite, and Special Low Dispersion (SLD) glass
elements. By optimizing the power alignment of the lens, chromatic aberration
has been corrected, achieving high image quality through the entire focusing
range. It is supplied with a built-in Petal-Shaped
lens hood which protects lens
from stray light, improving contrast and image quality. Moreover, the hood keeps
moisture or wind-blown debris off the lens and protects the front barrel from
the inevitable impacts against walls, door frames and other real-life obstacles.
