Macro Art Lens Sigma 70mm f / 2.8 DG for Sony E

Optimized for remarkable image clarity at close working distances, the Sony E-mount 70mm f / 2.8 DG Macro Art Lens from Sigma is a true 1:1 macro lens, suitable for close-up and macro subjects. As a member of the esteemed Art lens series, this first telephoto short is also distinguished by its sophisticated optical design using two FLD elements, two SLD elements, an anomalous partial dispersion/high refractive index element and two aspherical elements to limit chromatic aberrations and aspherical elements to limit chromatic and refractive index aberrations.

Benefiting the imaging assets is a coreless DC motor that offers fast and accurate autofocus performance along with full-time manual focus override. The physical design uses thermally stable composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting accuracy.

As part of the Art line of Sigma's Global Vision series, this lens is designed for truly remarkable optical performance and is ideal for creative and artistic applications.

Short telephoto focus, this lens is designed for Sony frameless, unmounted Full-frame cameras, however, it can also be used with APS-C models where it provides an equivalent 105mm focal length.

Two Low Dispersion F (FLD) elements, two Special Low Dispersion (SLD) elements and one anomalous partial dispersion/high refractive index element are presented in the optical design and help reduce color fringes and chromatic aberrations for greater color clarity and accuracy.

Two aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate representation.

The true macro design offers a maximum magnification of size 1: 1 to full size along with a minimum focusing distance of 10.2" to suit work with close-up subjects.

A super multi-layer coating has been applied to the lens elements to minimize lens flare and ghosting, and helps produce images with contrast and neutral color, even under backlit conditions.

The rounded nine-leaf diaphragm contributes to a soft and pleasant bokeh quality.

The coreless DC motor is used for fast and accurate autofocus performance. In addition, an updated focusing algorithm, full-time manual focus override, a large rotation angle and a cable focus system allow for greater and controllable focus adjustment.

The lens is constructed using a thermally stable composite material (TSC), along with traditional metals, for greater accuracy and use in wide temperature variations.

The bayonet mount is constructed of brass to ensure accuracy and durability. In addition, rubber sealing is incorporated into the mounting design to make it dust and splash resistant.

Compatible with the optional EM-140 DG MAC ring flash when used in conjunction with the 65 mm macro flash adapter for even illumination at close working distances.

Compatible with optional TC Teleconverters TC-1401 and TC-2001 to extend the effective focal length of the lens without losing autofocus functionality.
