Sigma 70mm f2.8 DG Macro A lens - Sony E-Mount

The Sigma 70mm F2.8 DG Macro lens for Sony full frame E-mount cameras 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.

Design prioritizing 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 product optimal results at all focal lengths. 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 colour streaking.

Focus-by-wire system for comfortable and precise focusing
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.
