The SIGMA USB DOCK UD-01 is a convenient dock for updating lens firmware and adjusting settings. I used it once, but I'm selling it because I don't plan to use it anymore. In addition to the main unit and the dedicated USB cable, the original box and instruction manual are included. (Everything in the images is included.) - Model Name: USB DOCK UD-01 - Brand: SIGMA - Accessories: USB cable, instruction manual, warranty card - Package: Original box Thank you for looking.
