Sigma Introduces New DG DN Art Lens

Sigma has announced the 35 mm f/1.4 DG DN Art lens, designed exclusively for Sony E and Panasonic/ Leica/Sigma L-mount bodies.

The lens incorporates 15 elements in 11 groups with two Special Low Dispersion (SLD) elements, an Extraordinary Low Dispersion (ELD) element, an ‘F’ Low Dispersion (FLD) element and two aspherical elements. The lens’ optical construction utilises Sigma’s optical design technology, minimising all types of aberration including axial chromatic aberration, which cannot be corrected in-camera.

The lens is reportedly able to control sagittal coma flare, stopping bright points of light from flaring out near the edges of the frame. Owing to its 11 rounded diaphragm blades, the lens displays smooth, round bokeh with Sigma’s anti-ghosting and antiflare technology.

The lens’ focussing mechanism features a stepping motor that controls a focussing lens group composed of a single, lightweight element, making the AF responsive and quiet.

Its aperture ring allows aperture to be controlled via the lens, or when set to Auto, using the camera. An aperture lock switch on the lens body allows the aperture ring to be locked in Auto so that it’s not accidentally knocked during shooting. The aperture ring can be de-clicked, allowing users to adjust exposure. Also on the lens barrel, is a focus mode switch and an AFL button, which can be customised to a desired function from within the camera menu. A petal type lens hood is included in the box, which helps reduce flare and offers the lens added protection if dropped. The hood has a lock mechanism that keeps it attached securely to the lens and comes with a rubberised grip. The dust and splash proof structure provides sealing on buttons and there’s a rubber gasket around the mount. acoating applied to the front element. As of now, no pricing or availability related information has been revealed by the company.
