I incorrectly wrote: "BTW. The F90X has an interesting 'audible battery indicator'. For about 5 last frames before the 'Err' would happen, the ***rewind*** sound is clearly louder and different. I never look at the display indicator. I change the batteries after hearing this sound. Then the cells are really empty." Of course, I was talking about the film advance which becomes slower and louder for the last possible frames before the batteries are fully exhausted. Sorry, Ilkka
