Related Questions and Answers

Q: 1. what lenses will this work with i have a 70-300 mm dg macro?

A: No. Sigma USB dock is only compatible with Sigma global vision lenses which includes Art, Sport and Contemporary product line.

Q: 2. Does Canon have a similar device for their lenses (EF & EFS)?

A: No, Canon does not have it. Canon do update camera body firmware to debug/improve Canon lens performance. Sigma and other lens manufacturers cannot interact with Canon firmware. All they can do is to adapt lens firmware to Canon camera body manufacturer firmware. To do so, the lens has to be connected to computer/internet to install newer lens firmware. Canon does it by direct camera body USB connection to a computer (details in camera manuals), Sigma does it through the lens USB Dock device. Also USB Dock is used to customize some lens settings at owner shooting preferences and focus micro adjustments. Canon customization and lens focus micro adjustment can be done through camera body menu for each individual lens (details in manual for each camera model).
