If you own a SIGMA Global Vision lens (Art, Sports or Contemporary) for digital SLR cameras and you want to update your firmware, customize settings or calibrate focus, follow along with Tech Rep Aaron Norberg as he walks through the steps needed to keep your lens up-to-date with the SIGMA USB Dock and SIGMA Optimization Pro software.
Note that DN lenses (made for mirrorless cameras) can be updated through the camera body without a USB dock, although the same software is required.
