Sigma USB DockCurrently, only lenses from the Sigma Global Vision program (Art, Contemporary and Sports lenses) are compatible with the Sigma USB Dock.

Sigma may be working on a firmware solution to extend this possibility to older lenses. It’s not known yet whether all Sigma lenses will be concerned, or just a few ones.

Such an update would provide them with better operation (autofocus speed/accuracy improvement) and compatibility (less on-body errors) with current and future camera bodies.
