Sigma Launches 50-120mm F2.8 Contemporary Telephoto Zoom Lens

Sigma Corporation of America today announced the Sigma 50-120mm F2.8 DC OS | Contemporary, a telephoto zoom for APS-C mirrorless cameras that covers roughly 75-180mm in full-frame terms at a constant F2.8. This lens completes Sigma's constant-F2.8 Contemporary zoom series alongside the 10-18mm F2.8 DC DN and the 18-50mm F2.8 DC DN, giving small format camera operators ultra-wide to telephoto coverage at F2.8 in three lenses that together weigh less than 2.2lb/1kg.

The new 50-120mm F2.8 DC OS | Contemporary fills the role of the classic 70-200mm F2.8, the go-to lens for portraits, events, and indoor sports, but in a fraction of the size and weight. At 13.8 oz/390g and 3.9in/99mm, it delivers the reach, bokeh, and subject compression equivalent to a full-frame 75-180mm F2.8 in a lens that balances on a compact APS-C body and fits in a small shoulder bag. Paired with the 10-18mm and 18-50mm, the 50-120mm gives APS-C shooters a three-lens F2.8 kit spanning ultra-wide to telephoto (roughly 15-180mm equivalent) for less than 2.2lb/1kg in total, light enough to carry all day on travel, documentary, or wedding assignments.

The lens features optical stabilization rated up to 6.5 stops, a dedicated aperture ring, a fast linear autofocus motor, a design that minimizes focus breathing for video, and a dust- and splash-resistant build with a water- and oil-repellent front element. The 50-120mm is the first APS-C zoom in Sigma's Contemporary line to include an aperture ring, a feature long requested by photographers and filmmakers who prefer to set exposure by hand.

Sigma's OS2 algorithm delivers 6.5 stops of correction at 50mm and 4.5 stops at 120mm, letting photographers use slower shutter speeds in dim venues and filmmakers capture steadier handheld footage, including on bodies without in-body stabilization. An optical design that minimizes focus breathing keeps framing steady as focus shifts between subjects, and the HLA linear motor drives the focus group for fast, quiet autofocus.

The lens is priced at $799 USD and will be available from Sigma-authorized dealers starting Thursday, October 22, 2026. Made in Aizu, Japan, the lens is designed, built, and tested at Sigma's own factory, ensuring strict quality control and uniform optical performance while nurturing local craftsmanship.
