I just purchased the Canon 40mm pancake lens for my 40D. I noticed that the barrel of the lens extends when focused close. Do I need to be worried about making sure the barrel is retracted before turning off and storing the camera?
Because this lens is focus by wire, turning the focus ring when the camera is off / asleep does not do anything. The only way to retract the lens is to focus on something at infinity or set it to manual focus and turn the ring before it turns off or goes to sleep. This seems like a lot of work and something I am going to frequently forget.
