Sigma has revealed its latest lens designed for full-frame mirrorless cameras. Available in Sony E and Leica L mounts, the Sigma 35mm F1.4 DG DN Art promises top-notch optics, fast quiet AF, and a comprehensive set of physical controls.

The firm says that the new optic has been completely redesigned compared to its existing 35mm f/1.4, which was originally designed  for full-frame DSLRs. It’s based on a 15-element, 11 group design with an array of special elements to minimise aberrations: one ‘F’ Low Dispersion glass (FLD), one Extra-Low Dispersion (ELD), two Special Low Dispersion (SLD) and 2 aspherical elements. In particular, longitudinal chromatic aberration is said to be minimised, as is coma, which should make the lens appealing for astrophotography.

Autofocus employs a stepping motor that drives a single lightweight element, which promises rapid, silent focusing. There’s a focus mode switch on the lens barrel, along with an AFL button whose function is customisable from the camera body. Also on board is a declickable aperture ring that can be locked at any setting.

As we’d expect at this level, the lens features a dust and splash-proof design that includes a rubber seal around the mount, along with a water and oil-repellent coating on the front element. A petal-type hood is included in the box, complete with a push-button lock. Physically the lens is similar in size to its DSLR predecessor, at 76mm in diameter and 110mm in length. It weighs 645g, and accepts 67mm filters. The minimum focus distance is 30cm.
