There is a USB-C port on one side of the lens that can be used to install firmware updates. Buyers should note that compatibility with some cameras is limited – full compatibility is currently not guaranteed with some older cameras such as the Leica SL or the Sony A7s, and autofocus in video mode does not work correctly even on newer Leica SL cameras or on the Sigma fp and Lumix S1 series.
