Not everyone keeps the batteries in their Leica's. I for one took the batteries out of my MP as the meter distracted me too much.
Yeah... I know the MPs the only Leica I've ever owned that even had a place to put batteries 🙂 but he touches the shutter button several times, changes the shutter speed and then looks through the VF again and again, obviously not just re-focusing... I don't think he'd do that if there weren't any batteries in it.
