Part of the Sigma Art Line whose goal is to deliver remarkable optical
performance that supports artistic and creative applications, this Sigma 35mm f/1.2 DG DN Art lens
is wide angle prime lens designed for full frame Sony E-mount
mirrorless cameras. On a APS-C model, it provides an equivalent focal
length of 53mm. This 35mm lens is the first of Sigma prime lenses to
feature a very bright and fast constant f/1.2 maximum aperture that
delivers high image quality and selective focus effects, as well as
benefits working in challenging lighting condition. A combination of
three special low dispersion (SLD) glass elements and three aspherical
elements, including a double-sided one, reduce a range of aberrations to
achieve improved clarity and colour accuracy, and increased sharpness
and rendering accuracy.
The optics is complemented by a large Hyper Sonic Motor (HSM) that
delivers a fast and quiet autofocus performance. Switch over to manual
control anytime by simply rotating the focus ring. The manual aperture
ring can be de-clicked for silent aperture operation to reduce noise
while recording video. In addition, the built-in autofocus-lock (AFL)
button can be flexibly assigned more functions to increase the range of
available operations on the lens. A rounded eleven-blade diaphragm
affords a smooth and pleasing bokeh quality. For increased robustness
and working in harsh environmental conditions, the lens is constructed
to be weather resistant with a brass bayonet to improve mounting
accuracy and rigidity. Furthermore, the front element of the lens is
coated with a water- and oil-repellent coating.
