Key Features

The Sigma USB Dock connects Sigma SA-mount lenses to a computer so you can update lens firmware and dial in focus behavior through Sigma Optimization Pro, instead of sending the lens in for adjustment.

It only works with Sigma's Global Vision lenses in the SA mount — Art, Contemporary, and Sports lines.


  • Function: connects Sigma SA-mount lenses to a computer for firmware updates and focus calibration via Sigma Optimization Pro software.
  • Lens Compatibility: works only with Sigma Global Vision Art, Contemporary, and Sports line lenses using the Sigma SA mount.
  • Focus Adjustment: offers 4 focus categories for prime lenses, and 16 categories for zooms (4 focal-length options by 4 shooting-distance options).
  • Sports Line Extras: Sports line lenses get 3 additional AF speed modes, focus-distance range limiting, and 3 Optical Stabilizer modes.
