Sigma 70mm f/2.8 Art DG Macro for Sigma

Sigma 70mm f/2.8 Art DG Macro for Sigma

The new Sigma 70mm F2.8 DG Macro is the first prime macro lens to be adorned with the Art badge. Fully redesigned to deliver exception 1:1 (life-sized) magnification, it prioritizes optical performance, fulfilling the demanding image quality requirements that define the Art line. In the standard to mid-telephoto range, it delivers stunning resolution and incredible clarity that greatly exceed expectations for a macro lens. The coreless DC motor further enhances image quality, while an optimized algorithm helps offer extremely smooth autofocus performance for a weightier, high-performance lens. The lens features an extending, floating, two-group focus mechanism. This configuration minimizes aberration to produce optimal results at any focus distance.

Art Lens

Engineered for those who see photography as an expression of self, Sigma’s Art line offers sophisticated optical performance and abundant expressive power to deliver faithfully on your artistic vision.

DG - DG for Digital

Sigma's DG lenses are specifically designed to deliver the ultimate level of performance on full frame digital SLRs. Sigma DGs also maximize the abilities of 35mm SLR cameras and APS-C size DSLRs. Thanks to a complete and comprehensive approach to the correction of chromatic aberrations, you will experience incredible image clarity and smoothness. Specific attention was paid to helping eliminate color fringing often caused by lateral chromatic aberration, a problem that is magnified at high resolution in digital photography. DG lenses provide exceptionally high contrast along with subtle gradations in tone and color. Super Multi-Layer Coating, along with Sigma's optimized optical design work to reduce reflections between the image sensor and the lens surfaces. The large image circles of DG lenses mean there will always be enough peripheral illumination to avoid vignetting.

Focus-by-Wire

The focus-by-wire system eliminates the direct mechanical connection between the focus ring and the focus drive system. Controlled by SIGMA’s latest algorithm, a newly developed coreless DC motor adjusts focus with optimal speed and low noise. Full-time manual focus is available even during autofocus, allowing the photographer to make minute focus adjustments simply by turning the focus ring. In addition, the focus ring’s large angle of rotation helps the photographer achieve the extremely precise focusing required for effective macro photography.

Top-level Optical Performance

In order to realize top-level performance at every shooting distance, the lens features an extending, floating, two-group focus mechanism. This configuration minimizes aberration to produce optimal results at any focus distance. To minimize axial chromatic aberration, the optical system incorporates two FLD glass elements, two SLD glass elements, and one element with a high rate of anomalous partial dispersion and a high index of refraction. In addition, two aspherical lens elements help increase resolution at close shooting distances. This optical system makes possible a razor-sharp in-focus area contrasted with a bokeh area free of color streaking.

Mount Construction

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

Compatibility

The Sigma 70mm F2.8 DG Macro Art lens is compatible with Sigma Tele Converters, Mount Converter MC-11 and Sigma USB Dock.
