I just got mine out and tested it. Here is what happens. Under autofocus it makes noise when the camera does it. It makes no noise when I move it myself. Under manual focus, it makes the same noise as if it was under autofocus and the camera was moving it. So, YES it does make noise in manual mode and it is quite loud. I am using it on a 5dIII with the updated firmware.
5dIII; 40mm 2.8, 16-35mm 2.8L II, 100mm Macro 2.8L IS, 70-300 4-5.6 IS, 70-200mm 2.8L II, 24-70mm 2.8L II
