History

    Stunning resolution and clarity
    for a breathtaking visual experience—
    a razor-sharp macro lens joins
    the Art line

    The successor of the legendary,
    razor-sharp macro lens—
    the SIGMA MACRO 70mm F2.8 EX DG

    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.

    Features

    Design prioritizing
    optical performance

    Top-level performance at every shooting distance

    • FLD glass
    • SLD glass
    • Aspherical lens

    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.

    Designed to minimize flare and ghosting

    From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

    Exclusive low-dispersion glass

    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.

    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.

    Fast AF with full-time manual focus

    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.

    Mount with dust- and splash-proof construction

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

    * Except for SIGMA mount

    Rounded diaphragm

    The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

    High-precision,
    rugged brass bayonet mount

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

    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

    Compatible with Canon Lens Aberration Correction

    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.

    Compatible with
    ELECTRONIC FLASH MACRO EM-140 DG

    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

    Compatible with
    SIGMA TELE CONVERTERS*1

    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.

    Compatible with
    Mount Converter MC-11*

    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.
