More Info on Sigma's SM Dock
In an interesting development, four months ago, Sigma announced a dock that allows you to connect your Sigma lens to your computer and adjust custom settings, but we have today we have more information, expanding on what we already posted then. You can adjust setting like a new minimum focus distance, autofocus speed, optical stabilization parameters and more. It'll even let you update the lens firmware. This is pretty neat, I think, and the first such product of its kind to my knowledge.
