SIGMA USB DOCK FOR SONY UD-01

Sigma USB Dock for Sony A-mount lenses

The Sigma USB port allows you to connect your Sigma Global Vision lenses to your computer to update the firmware and adjust the focus settings using the Sigma Optimization Pro software.
This base is only compatible with Sigma Art, Contemporary and Sports line lenses with Sony A lens mount.
Sigma Optimization Pro
Once a Sigma Art, Contemporary or Sports line lens is connected, you can use the Sigma Optimization Pro software to configure the focus settings and update the lens firmware.
Focus settings
For all lens lines, there are four categories for main lenses and 16 categories (four options for focal length, four options for shooting distance) for zoom lenses available. These categories allow you to set certain focus settings to best suit your personal shooting style.
Specific sports line configurations
If you use a sports line lens, additional lens settings are available: three different AF speed modes to change how quickly the lens changes focus; the ability to restrict focus distances within a specific range to suit your personal shooting habits; and three optical stabilizer modes to fit the way you are shooting.
