IS can be left on using a monopod. Still wondering about the focusing issue..tried it again and the same thing happened...a stuttering vibration at times when refocussing with the subject thrown just slightly out of focus to start with and sometimes ending with sub optimal focus. Tried it with my Canon 100 f2.8 macro and it didn't happen.
