Sigma 35mm F1.2 DG DN Lens - Sony E-Mount

The Sigma 35mm f1.2 DG DN Art is the first wide-angle AF lens with F1.2 maximum aperture for full-frame Sony mirrorless cameras. This lens enables a creation of artwork with astounding resolution and large bokeh effects, such as portraits that make use of a shallow depth of field. It brings the development concept of the Art line “pursuit of ultimate image quality” to the next level. While utilizing optical correction function inside the camera, aberrations that are difficult to post-process are thoroughly corrected thanks to the optical design and it thereby enhances resolution.

Outstanding build quality
The exterior barrel is made of a polycarbonate called Thermally Stable Composite (TSC). Not only is this very strong and light, but it has a similar thermal expansion rate to aluminium. This ensures that the interior aluminium parts and the exterior TSC parts behave in a uniform way as temperatures change.
The focus ring is rubberised for easier operation, and focusing is internal, meaning the lens never changes length. This makes it ideal for use on a gimbal as the centre of gravity remains fairly constant. Towards the rear of the barrel is an aperture ring so that aperture can be changed on the lens, and it has an Auto setting should users prefer to change aperture using the camera.
To reduce flare and ghosting in bright sun, and to help protect the front element from damage if dropped, the lens has a robust petal-type lens hood with lock button. A rubberised ring on the hood makes for easier removal and fitting. The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.

Professional feature set
A range of controls on the lens include an AF/MF switch, and a customisable AFL button (depending on camera model). The lens also has a click/de-click switch so that the aperture ring can be adjusted smoothly rather than in hard stops, which may be useful for film-makers. A powerful stepping motor ensures fast, accurate and quiet AF and excellent AF tracking capability.

High-performance optics
The 35mm F1.2 DG DN | Art boasts outstanding optical quality, with excellent detail rendering across the whole frame even wide open at F1.2. The lens has an advanced optical design made up of 17 elements in 12 groups, including 3 aspherical elements and 3 SLD elements. These precision-crafted elements help to ensure razor-sharp results and eliminate chromatic aberration, flare, distortion and vignetting.
Advanced Super Multi-Layer Coatings reduce flare and ghosting when working in bright direct sunlight, creating high-contrast images with rich colours and strong blacks.

Good for close-up photography
With a magnification ratio of 1:5.1, the 35mm F1.2 can focus on objects at just 16.5cm from the end of the lens. This gives the lens good close-up capability, making it ideal for flower and food photography.
