Sigma 70mm f/2.8 DG Macro Art Lens - Sigma fit
Sigma 70mm f/2.8 DG MACRO Art Lens Summary - Sigma Fit
The Sigma 70mm f/2.8 DG MACRO Art Lens is designed to provide stunning optics above all else. Using an advanced optical system results in outstanding high-resolution image quality with clarity that greatly exceeds expectations for a macro lens.
Sigma have continued their efforts to develop outstanding, new lenses with the 70mm MACRO Art. The optical system includes 13 elements in 10 groups, minimising axial chromatic aberration and delivering a razor-sharp in-focus area contrasted with a bokeh area free of colour streaking. Paired with the extending, floating, two-group focus mechanism and coreless DC focus motor, you are able to achieve beautiful macro images with fast, precise focusing.
This exceptional design paired with top quality materials and construction makes this the go-to macro lens for close-up high resolution images.
Sigma 70mm f/2.8 DG MACRO Art Lens Features in Detail
The long-awaited first macro lens in the Art line
In recent years, macro lenses in the standard range have tended to employ inner focusing with the goal of maximizing autofocus speed. In contrast, the new SIGMA 70mm F2.8 DG MACRO - Art lens is designed to prioritize 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. Photography enthusiasts will recall a certain legendary, razor-sharp macro lens—the SIGMA MACRO 70mm F2.8 EX DG—and be glad to learn it is available in a new form, updated with outstanding Art line quality.
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 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 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.
Compatible with full-frame Sony E-mount cameras
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 Corporation.
Compatible with Canon Lens Aberration Correction
The Canon mount 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, further enhancing image quality.
Compatible with ELECTRONIC FLASH MACRO EM-140 DG (adapter required)
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 MACRO FLASH ADAPTER can also be added so as to accommodate 72mm macro flash products and accessories, including macro flashes other than EM-140 DG as well as ring lights.
Compatible with SIGMA TELE CONVERTERS
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, while SIGMA TELE CONVERTER TC-2001 allows the lens to be used as a 140mm F5.6 mid-telephoto macro with manual focus.
