Nikon F Mount. We carry this product in multiple mounts with this one being the Nikon version.

Limited Compatibility. The USB Dock is only compatible with Sigma’s Global Vision line of lenses listed in the recommended section on the left-hand side of this page. Please note there are three lists of lenses: Prime, Zoom, and Crop-Frame.

Customized Calibration. With four adjustable categories to customize focus distance for prime lenses and sixteen for zoom lenses (4 distances x 4 focal lengths), the USB Dock allows precision calibration for the specific camera / lens setup. Additionally, when used with certain lenses you can also customize three different AF speed modes, three Optical Stabilizer modes, and constrain focus distances within a specific range.

Sigma Optimization Pro. The free Sigma Optimization Pro software is simple to use, enabling you to update firmware as well as make focus adjustments on the latest Sigma Global Vision lenses.
