Sigma 105mm f/2.8 DG DN Macro Art Lens (L Mount)

With a magnification ratio of 1:1, this true macro lens for mirrorless cameras is designed for focusing extremely close to a subject to capture it in a very high level of detail. It’s perfect for photographing natural-world objects such as insects and plants, but it can also be used for non-macro subjects such as portraits and landscapes.

The lens delivers exceptional image quality, with razor-sharp results across the whole frame at all apertures. The maximum aperture of f2.8 ensures fast shutter speeds in low-light conditions as well as a shallow depth-of-field for blurry backgrounds. A number of professional-level features are built in, including a manual aperture ring with de-click and lock switch, an AFL button, a focus limiter and a dust- and splash-resistant structure.

Outstanding Build Quality

The 105mm F2.8 DG DN MACRO delivers the exceptional build quality you’d expect from an Art-line lens, both in the materials used and the quality of craftsmanship.

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 the same 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 polycarbonate lens hood The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.
