  • The first macro lens in the Art line with stunning resolution and clarity creating a breathtaking visual experience.
  • The SIGMA 70mm F2.8 DG Macro / Art 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 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.
  • Flare and ghosting reduction:
  • 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.
  • At the prototyping stage, SIGMA used not only simulations but actual photographic experiments to assess flare and ghosting under multiple criteria, identify the causes of these issues under a wide range of situations, and take measures to mitigate them.
  • SIGMA's Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.
  • High-precision construction and functionality:
  • In order to ensure high accuracy of the product, all metallic parts and the new compound material, TSC (Thermally Stable Composite), which has high affinity to metal parts, are housed internally.
  • Mount with dust-and splash-proof construction: The lens mount incorporates rubber sealing* to protect the mount from dust and water drops.
  • Brass made bayonet mount: The lens is incorporated with a brass made bayonet mount which has both high accuracy and durability for long sustainability.
  • A hood with a high-quality rubberized connector: It is designed for intuitive use by ensuring a better feel for handling.
  • Compatible with Tele Converters:
  • The lens is compatible with SIGMA TELE CONVERTERS (sold separately) designed for the 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. By using tele converters, it is possible to shoot at more than 1x magnification.
  • * Autofocus available at 0.5m to infinity
