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

Sigma's 70mm f/2.8 DG Macro Art lens for Sony E-mount delivers exceptional performance in macro and close-up photography through its true 1:1 magnification ratio. The sophisticated optical construction incorporates FLD and SLD elements alongside aspherical components, effectively minimizing chromatic and spherical aberrations to achieve superior sharpness and color fidelity across the frame. Multi-layer coatings reduce flare and ghosting, ensuring excellent contrast even in challenging lighting. The nine-blade diaphragm renders smooth, natural bokeh, making this Art series prime equally capable for both detailed macro work and short-telephoto applications.

This macro lens features a coreless DC motor enabling rapid, precise autofocus with seamless manual focus override capability. Built with Thermally Stable Composite construction, it maintains optical performance across diverse environmental conditions while resisting thermal fluctuations. The brass bayonet mount provides exceptional rigidity and repeatable mounting accuracy, ensuring consistent performance and reliability for demanding macro photography applications.

Key Features:

• As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
• Short-telephoto prime, this lens is designed for full-frame Sony E-mount mirrorless cameras, however can also be used with APS-C models where it provides a 105mm equivalent focal length.
• Two F Low Dispersion (FLD) elements, two Special Low Dispersion (SLD) elements, and one anomalous partial dispersion/high refractive index element are featured in the optical design, and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.
• Two aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.
• True macro design affords a life-size 1:1 maximum magnification along with a 26cm minimum focusing distance to suit working with close-up subjects.
• A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
• Nine-blade rounded diaphragm contributes to a smooth and pleasing bokeh quality.
• Coreless DC motor is used for quick and accurate autofocus performance. Additionally, an updated focusing algorithm, full-time manual focus override, large angle of rotation, and focus-by-wire system enable increased and controllable focus adjustment.
• The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.
• The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
• Compatible with optional TC-1401 and TC-2001 Teleconverters to extend the effective focal length of the lens while retaining autofocus functionality.
