I did notice that it kept trying to focus on things while moving it but not half-pressing the shutter button.

This sounded very strange to me until I read you are using the 70D.  This is a stretch, but if you are in video mode, with the dual-pixel autofocus, the lens will try to autofocus continuously... is that possible?
