Prime-Level Clarity, Zoom-Level Freedom

Imagine the sharpness of a 600mm prime lens—now imagine having that same exceptional quality across a zoom range that stretches from 300mm to 600mm. This lens makes that dream a reality. Its innovative inner zoom design maintains perfect balance and minimizes shifts in the center of gravity, giving you greater control and comfort when shooting in dynamic environments.

Engineered for Perfection in Every Frame

Inside this powerhouse, 28 meticulously crafted lens elements across 21 groups—including FLD and SLD glass—work together to eliminate chromatic aberrations and deliver razor-sharp detail across every focal length. The result? Extraordinary clarity and true-to-life color accuracy, whether you’re shooting at 300mm or pushing the boundaries at 600mm.

Stability That Moves with You

Conquer camera shake with Sigma’s advanced OS2 algorithm, offering up to 5.5 stops of optical stabilization. From still shots to smooth panning sequences, this lens adapts to your shooting style. Whether capturing rapid movement or filming cinematic pans, the dual stabilization modes ensure sharp, blur-free results in any scenario.

Built for the Toughest Challenges

Crafted from a durable magnesium alloy with a lightweight carbon fiber hood, this lens offers outstanding resilience without adding bulk. A thermal insulation coating protects performance under harsh sunlight, while a dust- and splash-resistant structure ensures reliability in unpredictable conditions. Every detail has been engineered with the professional in mind—down to the robust, Arca-Swiss compatible tripod socket and a convenient drop-in filter holder for creative flexibility.

Extended Functionality, Total Control

The newly designed function ring offers intuitive focus control—whether you’re locking onto a pre-set focus point for split-second reactions or using Power Focus Mode for smooth cinematic transitions during video shoots. This intuitive handling empowers photographers to capture every moment exactly as they envision.
