Sigma has long been recognized for offering high-quality third-party lenses that provide a perfect balance between optical performance and affordability. With a commitment to future-proofing its products, Sigma has just rolled out a new firmware update for nine Contemporary prime lenses, designed to maximize compatibility with the Sony A9 III mirrorless camera.

The Sony A9 III, a standout in the world of sports photography cameras, continues to raise the bar with its impressive ability to shoot at up to 120 frames per second, making it one of the fastest cameras on the market. However, achieving these blistering speeds requires more than just a fast shutter, lenses need to keep up as well.

This is where the new firmware update for Sigma’s Contemporary line of prime lenses comes in. The update is aimed at ensuring smooth, uninterrupted autofocus performance, even when the Sony A9 III is pushing the limits of its continuous shooting capabilities.

According to the official release notes, the firmware update brings two key improvements:

" • Compatibility with continuous shooting of up to approximately 120 frames per second has been added for the autofocus modes (AF-S/DMF/MF) on Sony A9 III cameras.

• Improved Operational Stability"

The firmware update applies to nine Sigma prime lenses from the highly-regarded Contemporary line, known for their compact size, robust build quality, and impressive optical performance at a more accessible price point than native Sony lenses.

Here are the specific lenses included in this update:
