70mm F2.8 DG MACRO

Top-level performance at every shooting distance

The degree to which light is refracted by glass depends on the light’s wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, Sigma lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives Sigma lenses superlative image rendition undiminished by residual chromatic aberration.

Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.

Note: The operation of full-time MF may vary based on mount type.

The lens mount incorporates rubber sealing to protect the mount from dust and water drops.

* Except for Sigma mount

The version of this lens compatible with Sony E-mount mirrorless cameras contains the same optical system as for SLRs. Sigma MOUNT CONVERTER MC-11 is not required, as the lens performs the same functions as the converter, including in-camera image stabilization and in-camera lens aberration correction. In addition, the lens is compatible with Sony’s Continuous AF, which is not addressed by MOUNT CONVERTER MC-11. Sigma plans to offer over time Sony E-mount versions of every full-frame prime lens currently available in the Art line, from 14mm to 135mm.

Note: This product is developed, manufactured and sold based on the specifications of E-mount which was disclosed by Sony Corporation under the license agreement with Sony

The Canon mount version of this lens is compatible with the Canon Lens Aberration Correction function.* Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.

* Function not available on all Canon cameras. Available corrections may vary depending on the Canon camera model.

(*)Canon camera compatibility

Exclusively for Sigma 70mm F2.8 DG MACRO | Art, the 65mm MACRO FLASH ADAPTER makes the lens compatible with ELECTRONIC FLASH MACRO EM-140 DG (both accessories sold separately).*Thanks to the 72mm filter thread, a 72mm adapter can also be added so as to accommodate macro flashes other than EM-140 DG as well as ring lights.

* Sigma SA mount only

The lens is compatible with Sigma TELE CONVERTERS (sold separately) designed for the company’s new lens lines. Sigma TELE CONVERTER TC-1401 allows the lens to be used as a 98mm F4 mid-telephoto macro with autofocus functionality,*2 while Sigma TELE CONVERTER TC-2001 allows the lens to be used as a 140mm F5.6 mid-telephoto macro with manual focus.

*1 Not available for L-Mount and Sony E-mount lenses
*2 Autofocus available at 0.5m to infinity.

Mount Converter MC-11 allows you to use your Sigma SA mount and Sigma EOS mount (Canon-compatible) interchangeable lenses with the Sony E-mount camera body.
