It's designed as a high-quality alternative to the camera manufacturers' equivalents at a substantially lower cost even at its ca. At the same time the company announced three new lenses, one in each class, with the 35mm F1.4 DG HSM as the first release in the Art category. The hood has a lock mechanism that keeps it attached securely to the lens, and its rubberised grip makes it quick and easy to attach and remove.At Photokina 2012, Sigma announced a reorganization of its lens lineup into three categories - 'Contemporary' covering lightweight, flexible zooms, 'Sports' for larger telephoto lenses, and 'Art' for a wide range of optics aimed at serious photographers, including ultra-wideangles, macros and fast primes. There’s also a water and oil repellent coating applied to the front element ensures that photographers can rely on it in any conditions.Ī petal type lens hood is included in the box, which helps reduce flare and offers the lens added protection if dropped.
The dust and splash proof structure provides sealing on buttons and along joins between constituent parts, and there’s a rubber gasket around the mount. The switch is ergonomically positioned to be controlled by the thumb during use. Also on the lens barrel is a focus mode switch ⑤ and an AFL button, which can be customised to a desired function from within the camera menu (depending on the model).

A big plus for film-makers, the aperture ring can be de-clicked, allowing users to seamlessly adjust exposure. 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 lens has an aperture ring that allows aperture to be controlled via the lens, or when set to Auto, using the camera. This ensures the best possible optical precision while keeping the weight of the lens to a minimum. This strong and light polymer has a very similar thermal expansion rate to aluminium, meaning that all parts of the barrel behave in a very similar way as the temperature changes. The barrel of the 35mm F1.4 DG DN Art is made with a combination of aluminium and a polymer called Thermally Stable Composite, or TSC. This makes the 35mm F1.4 DG DN Art particularly well-suited to portraits and close-ups, supported by its ultra-sharp image quality and minimal colour bleeding. Owing to its 11 rounded diaphragm blades, the lens displays smooth, round bokeh so that out-of-focus areas are not distracting.

This keeps shots high contrast and free of excessive flare even when working in difficult light. The lens performs very well in backlit conditions thanks to Sigma’s anti-ghosting and anti-flare technology that it has cultivated through countless simulations and real-life testing.
#SIGMA 35MM MANUAL#
Manual focusing is smooth and precise, but with the right amount of resistance for film-makers. 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. The focusing mechanism in this lens features a stepping motor. This minimises all types of aberration including axial chromatic aberration, which cannot be corrected in-camera. 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 utilises SIGMA’s state-of-the-art optical design technology. The lens incorporates 15 elements in 11 groups. It includes ultra-fast AF, a de-clickable and lockable aperture ring and a customisable AFL button so it's well-suited to video shooting as it is still photography. Its wide-standard focal length and bright aperture make it perfect for a wedding, portrait and travel photography, as well as film making. The Sigma 35mm F1.4 Art is a durable, compact and lightweight prime lens designed for Sony mirrorless cameras.
