70mm f2.8 DG Macro SIGMA lens

More Info SIGMA Art

Optimized for remarkable image clarity at close working distances, SONY's 's SIGMA's E-mount 70mm f/2.8 DG Macro Art Lens is a true 1:1 life-size macro lens, well suited for close-up and macro subjects. As a member of the esteemed Art series of lenses, this first telephoto short is also distinguished by its sophisticated optical design that uses two FLD elements, two SLD elements, an anomalous partial dispersion/high refractive index element, and two aspherical elements to limit chromatic and spherical aberrations for greater clarity, sharpness, and color accuracy. A Super Multi-Layer also improves image quality by suppressing lens flare and ghosting to improve contrast and color fidelity in bright light conditions. In addition, a rounded nine-leaf diaphragm contributes to a pleasant bokeh quality.

Benefiting 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 within SIGMA's Global Vision series, this lens is designed to achieve truly remarkable optical performance and is ideal for creative and artistic applications.

• Short telephoto focus, this lens is designed for full-frameless cameras SONY without mount, however, it can also be used with APS-C models where it provides an equivalent focal length of 105mm.

• Two F Low Dispersion (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 stripes and chromatic aberrations for greater clarity and color 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 maximum 1:1 life-size magnification along with a minimum focusing distance of 10.2" to suit working with close-up subjects.

• A super-multilayer layer has been applied to the lens elements to minimize lens flare and ghosting, and helps produce contrast and neutral color images, even under backlight conditions.

• The nine-leaf rounded diaphragm contributes to a smooth 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 wired focusing 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 65mm 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.
