The Sigma USB Dock for Pentax Lenses works in conjunction with Sigma Optimization Pro software in order to connect your lens to your personal computer. The Dock allows you to connect your Sigma Global Vision lenses to your computer in order to update firmware and adjust focus setting parameters using the Sigma Optimization Pro software. The dock is only compatible with the Sigma Art, Contemporary, and Sports line lenses featuring a Pentax K lens mount. Once a Sigma Art, Contemporary, or Sports line lens is connected, you can use the Sigma Optimization Pro software to configure focus settings and update the lens firmware.

For all lines of lenses, there are four categories for prime lenses and 16 categories (four options for focal length, four options for shooting distance) for zoom lenses available. These categories allow you to set up certain focusing settings to better suit your personal shooting style. If using a Sports line lens, additional lens configurations are also available. The dock features three different AF speed modes to modify how quickly the lens changes focus. You can also constrain focus distances within a specific range to suit your personal shooting habits. Plus, the dock includes three Optical Stabilizer modes to suit the manner in which you are shooting. Sigma Photo Pro is available for Mac and PC computers.
