Using Sigma's Optimisation Pro software (included) you can update the firmware and configure the autofocus speed (AF), optical stabilisation (OS), and modify the minimum and maximum focusing distance. The Sigma USB dock will not work with Sigma's existing lenses and has been specifically designed for their new line of lenses, such as the Sigma 17-70mm f2.8-4 DC Macro OS HSM, 35mm f1.4 DG HSM, 30mm f1.4 DC HSM, 18-35mm f1.8 DC HSM, 24-105mm f2.8 DG OS HSM, 50mm f1.4 DG HSM, 18-200mm f3.5-6.3 SC Macro OS HSM and 120-300mm f2.8 DG OS HSM lenses. 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.
The Sigma USB Dock is designed for Pentax-fit Sigma Global Vision lenses, enabling users to fine-tune autofocus speed, optical stabilization, and focus limits via Sigma's Optimization Pro software. This allows for personalized lens performance adjustments to match individual shooting styles. However, it is strictly compatible only with Sigma's new line of Art, Contemporary, and Sports lenses featuring a Pentax K mount, and will not work with older Sigma lenses.
