Exceptional optical performance

Central to the design of the 35mm F1.4 DG DN | Art is its sophisticated optical performance, which is consistent with the development of all Art line lenses. 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, and as well as other high-performance glass, the lens’ advanced optical construction utilizes SIGMA’s state-of-the-art optical design technology, minimizing all types of aberration including axial chromatic aberration, which cannot be corrected in-camera.

Fast and quiet AF in a compact body

The focusing mechanism in the SIGMA 35mm F1.4 DG DN | Art features a stepping motor. This motor controls a focusing lens group composed of a single, lightweight element, which means AF is responsive and quiet, and is able to keep track of moving objects very effectively. Manual focusing is smooth and precise, but with the right amount of resistance for filmmakers.

Professional feature-set

On the body of the SIGMA 35mm F1.4 DG DN | Art is an aperture ring that 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 is not accidentally knocked during shooting. A big plus for filmmakers, the aperture ring can be de-clicked, allowing users to seamlessly adjust exposure. Also on the lens barrel is a focus mode switch and an AFL button, which can be customized to a desired function from within the camera menu (depending on the model). The switch is ergonomically positioned to be controlled by the thumb during use.

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 its rubberized grip makes it quick and easy to attach and remove.

On top of this impressive array of features and elegant exterior, the body of the 35mm F1.4 DG DN | Art offers an exceptional level of durability that helps it withstand long-term professional use as well as individual operating parts that give a good fit to the hand. The dust and splash resistant structure provides sealing on buttons and along joins between constituent parts, and there is a rubber gasket around the mount. There is also a water and oil repellent coating applied to the front element ensures that photographers can rely on it in any conditions.
