Sigma USB dock demo video released

Sigma recently released a demo video showing software of the late USB lens docking station in action. This dock is a very special product as it will allow users to adjust focus if there is a need for it (usually there is). Almost all modern DSLR cameras have the option to adjust AF accuracy, but often only as a single setting for every lens. This is a problem with zoom lenses since most tend to missfocus by different degree depending where in the zoom or focus range they are. Sigma USB dock will allow to set AF compensation at up to 4 focal lengths and at 4 different focus positions independently. There is also an option to adjust optical stabilization , focus limiter and AF speed. Click “continue reading” to view video:

The USB dock will be in sale early May for around $ 60.
