Compact black USB-C dock for Sigma L-Mount lenses

SIGMA

SIGMA USB Dock UD-11 for L-Mount Lenses

SKU CH-828A-D4RCK

A USB-C dock that updates firmware and fine-tunes manual-focus sensitivity on Sigma L-mount lenses, converters and the MC-21 adapter

  • Update lens firmware via USB-C
  • Customise manual-focus ring sensitivity
  • Compatible with Contemporary, Art, Sports lenses
  • Supports MC-21 mount converter updates
  • Works with TC-1411 and TC-2011 tele-converters

Designed for L-Mount lenses

The Sigma USB Dock UD-11 connects directly to compatible Sigma Contemporary, Art and Sports lenses plus the MC-21 mount converter and TC-1411 or TC-2011 tele converters. It provides a USB Type-C link to a computer so the Sigma Optimization Pro software can apply firmware updates and adjust manual-focus ring sensitivity.

For Sigma L-Mount owners needing firmware control

Photographers who own supported Sigma L-Mount glass or the listed converters can keep firmware current and tune MF response without sending equipment away. Users with other lens mounts, non-Sigma glass or no need for firmware changes will not benefit from this accessory.

Stable during extended configuration sessions

The dock maintains a reliable USB Type-C connection while Optimization Pro writes firmware to the lens or converter, preventing interruption that could corrupt the update. It draws power from the host port and stays cool enough for the sequential updates photographers run when preparing multiple units.
