Sorry if this has been covered already. Can I not manually lock the focus somehow in macro mode on my EX1r? I'm trying to shoot a simulation of a flying disc's POV as it flies toward a disc-golf basket. As the disc slowly rotates, I'm nearly touching the top of it with the lens hood (the disc itself is rotating on a spindle that is attached by an arm to the baseplate of the camera, which is attached to a glidecam unit, which is not attached to anything because I'm too poor to buy the vest). I was well aware of the MODE limitation (only wide angle, and only in "manual servo") but I just assumed I would be able to STOP the camera from focusing. What's happening is that the camera is shifting focus to the background as I execute the shot, even when the disc is not rotating. What gives?
