SIGMA 70-200 mm F2.8 DG DN OS Sports for Sony E-Mount

The eagerly awaited SIGMA 70-200 mm F2.8 DG DN OS Sports is a reliable and lightweight DG DN F2.8 large-aperture telephoto zoom lens specially designed for full-frame mirrorless camera systems, and is available for the Sony E-Mount. This high-performance lens combines high-speed AF, remarkably effective OS, exceptional mechanical reliability, and superior optical performance to meet the rigorous demands of professional-level photographers.
Prioritizing Quality
With features such as dust and splash-proof construction, high-performance optical stabilizer (OS) functionality, and an inner zoom mechanism that maintains barrel length during recomposing, it is tailored for the most demanding photographic conditions. Notably, it is the first SIGMA DN zoom lens equipped with a click-and-declick-type aperture ring. The streamlined optical design and multi-material structure, optimizing magnesium and TSC, result in a lightweight lens body. Additionally, a compact tripod collar and foot, along with a CFRP (carbon fiber-reinforced plastic) lens hood, contribute to minimizing weight. In comparison to the SIGMA 70-200mm F2.8 DG OS HSM Sports for DSLR cameras (1,805 g for SA mount), the SIGMA 70-200mm F2.8 DG DN OS Sports is significantly lighter.
Focus and Stabilization
The lens features Dual HLA-driven floating focus for fast and accurate AF, utilizing a high-thrust HLA (High-response Linear Actuator) as the focus actuator. The floating focus configuration, where two focus groups move in opposite directions, achieves extremely fast and highly responsive AF. The latest OS2 stabilization algorithm provides image stabilization of 7.5 stops at the Wide end and 5.5 stops at the Tele end. Notably, the SIGMA 70-200mm F2.8 DG DN OS Sports exhibits minimal focus breathing on both wide and tele ends, making it a potent lens for video applications. The minimal change in center of gravity ensures stable shooting in various situations, including handheld, on a tripod, and with a gimbal. During zooming, five groups move to suppress aberration fluctuation, maintaining high optical performance throughout the zoom range.
