Sigma UD-11 USB Dock for Canon EF-M Mount Lenses

The Sigma UD-11 USB Dock for Canon EF-M mount is a compact, precision accessory that connects your compatible Sigma EF-M lens directly to your computer via USB, unlocking the full potential of Sigma's free Optimization Pro software. Designed for photographers who demand the very best from their glass, the UD-11 allows you to update lens firmware as new improvements are released by Sigma, ensuring your lens always performs at its peak with the latest autofocus algorithms and optical corrections.

Beyond firmware updates, the UD-11 gives you granular control over manual focus operation — specifically the focus ring timing adjustment, which determines how much physical rotation of the focus ring translates into focus movement. This level of fine-tuning is invaluable for videographers and photographers who rely on precise, repeatable manual focus pulls, allowing you to tailor the lens behaviour to your exact shooting style and workflow.

The UD-11 is compatible with three Sigma Contemporary lenses in the Canon EF-M mount: the 16mm f/1.4 DC DN, the 30mm f/1.4 DC DN, and the 56mm f/1.4 DC DN. These are among the sharpest and most popular prime lenses available for Canon EF-M mirrorless cameras, and the UD-11 ensures you can keep them optimised and personalised throughout their lifespan. Setup is straightforward — simply mount the lens onto the dock, connect via the included USB cable, and run Sigma Optimization Pro on your Windows or macOS computer.
