Sigma unveils new APS-C zoom lens

Sigma announced the Sigma 50-120mm F2.8 DC OS | Contemporary during the Photo Video 2026 trade show on October 8, 2026. The lens is tailored for APS-C cameras, which use smaller image sensors than full-frame models, and is compatible with Sony E, Fujifilm X, and Canon RF camera mounts.

Lens features and design

The lens is notable for its constant f/2.8 aperture, which allows for consistent performance in low light, optical stabilization to reduce camera shake, and a compact design that makes it easier to carry. It joins Sigma’s existing APS-C lenses, forming a trio of constant f/2.8 lenses for APS-C cameras.

Technical specifications

The lens features 18 elements in 13 groups, including one FLD glass element, three SLD glass elements, and four aspherical lenses. These components help improve image quality and reduce distortions. It uses Sigma’s HLA autofocus motor, known for its speed and precision.

Availability and pricing

The lens is expected to be available from October 22, 2026, at a price of 799 €. It weighs under 400 grams and is weather-sealed, making it suitable for use in various environmental conditions. However, it lacks a manual aperture ring with continuous adjustment and does not have dedicated switches for autofocus/manual focus or optical stabilization.

Market positioning and competition

The lens will compete with the Fujinon XF 50-140mm F2.8 R LM OIS WR, which is priced around 1540 €. However, it is not available in the Nikon Z mount, a limitation that Sigma has not yet addressed. Sigma’s general director in France, Foucauld Prové, mentioned that discussions about Nikon Z mount support are ongoing.

APS-C lens market overview

Sigma’s APS-C lens lineup is described as more comprehensive than those of Canon, Sony, and Nikon, though Tamron also offers several APS-C zoom lenses in the Nikon Z mount. The Fujifilm X mount is highlighted as a significant driver for APS-C lenses, with the upcoming X-T6 expected to boost demand. Sony’s latest APS-C camera is the ZV-E10 II, released in 2024.

L-mount exclusion and strategy

Sigma decided not to produce APS-C lenses in the L-mount due to potential workload for engineers and production, as well as the potential of the APS-C format in other systems. This decision reflects a strategic focus on other mounts with higher market demand.
