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

The sigma 70mm macro is a full-frame Art-series macro lens for Sony E-Mount cameras, combining the versatility of a standard portrait focal length with the specialized close-focus capability required for macro photography of subjects including insects, flowers, textures, and small product details.

The sigma 70mm macro achieves true 1:1 life-size magnification with a minimum focus distance of 10.2 inches (26cm), allowing photographers to reproduce subjects at the exact same size as they appear in real life on the sensor, which is the defining standard of a true macro lens.

The sigma 70mm macro uses two FLD elements, two SLD elements, and additional low-dispersion and aspherical glass to control chromatic aberration, distortion, and field curvature across the full focus range from infinity down to 1:1 macro distance, maintaining consistent optical quality at all scales.

The sigma 70mm macro is driven by a coreless DC AF motor that provides smooth and controlled focus movement across its full focus travel from infinity to 1:1, with a manual override that allows the photographer to instantly switch to manual focus without changing any switches, essential for precise macro positioning.

The sigma 70mm macro uses a rounded 9-blade diaphragm that produces smooth circular bokeh in out-of-focus areas when shooting above macro distances, ensuring that background rendering is pleasing when the lens is used for portrait or general photography beyond its close-focus range.

The sigma 70mm macro features weather-sealed construction paired with a precision brass bayonet mount, providing dust and moisture resistance that makes it practical for field macro photography outdoors where dew, light rain, or dusty conditions are commonly encountered near subjects in nature.

The sigma 70mm macro applies Super Multi-Layer Coating to its optical elements to suppress flare and ghosting across the full focus range, maintaining contrast and color accuracy in the detailed close-up imagery where any reduction in micro-contrast would noticeably degrade the fine textures captured at macro scale.
