That’s a factory firmware update, and we haven’t yet had time to send Canon every lens in our stock. If this is a feature you need, please let us know and we’ll do everything we can to make sure you receive an updated copy. Are there any known issues with this lens? Due to a design flaw, the 114mm filter rotating lever may become jammed and inoperative. This has happened to nearly every copy of the hood we have, so we consider it normal behavior. Please be aware of this if you plan on using your own 114mm screw-on filters. What type of power source does this lens use? This lens requires a D-Tap power source.
