The Sigma USB dock makes it possible to connect the C, A, and S lenses to your computer, in order to use the Sigma Optimization Pro software. This way, you'll not only be able to update the lens's firmware, it's also possible to adjust the lens's focus parameters.
Several focus settings are available to fine-tune the parameters in the lens until they're exactly according to your preference. This'll provide you with an important service. Instead of having to send the lens away, you'll have 16 categories at your disposal to adjust the lens focus (4 options for the focal length x 4 options for the photography distance). For Sigma's sports line, there are also 3 AF speed modes you can fine-tune, 3 optical stabilization modes you can adjust to your liking, and you'll have the option of adjusting the focal distance adjustment.

It took me around 6 hours!! to calibrate the len with this usb dock. The reason is that they don't show you how to set up a good scenario to test your lens while calibrating all focus lens options. So you need to make sure that you have a good place to set up your camera and the objects you are going to use for your tests. If you ask me if it was worth it? The answer is, Hell Yeah!. The quality level of my photos after calibrating every distance for each focus len of the options on my 18-35 mm is astonishing. I'm traveling in South East Asia and my first test was to shot with the Sigma 18 to 35 mm in Angkor Wat, Cambodia, the results are unbelievable. The out of focus is totally fixed, specially the back focus issue I had with this len. I take better and more clear pictures as well. Before calibrating the len it was a frustration not to get sharp pictures but that is now totally fixed. From 10 photos 8 are sharp for sure, depending the situation, moving target, static objects, etc. The overall performance of this len is now totally improved after using the USB dock.

After a switch to sigma lenses, this Dock was recommended to me. More is possible for the lenses from the art, sport or contemporary line from Sigma. There are different setting options for each lens. But for all lenses from the aforementioned series, you can update the firmware and fine-tune the autofocus system.
My 24-105 art immediately received an update after connecting that made the autofocus even faster and even no longer produces sound in video mode (lens was already quite quiet)
My 18-35 art in combination with my camera has a back focus issue on some focus points. Can help immediately.
For a fellow photographer, 150-600 sports were updated and the speed of the optical stabilazor decreased (on request)
In short, an accessory that quickly pays for itself and thus has an edge over the "brand lenses". Here you can turn a great lens into a sublime lens!

Very easy to use. And does what it's supposed to do: update the firmware of your Sigma lens + offer the possibility to manually adjust your focus to your own liking.
A must for every Art series owner.
