Need a lot of battery power, because I'm schnellemal 150-400 photos a day on vacation. I want to make me over power shortage not worry. That's why I purchased separately 3 Patona battery set with charger. Everything works fine: Fast loading = schnellle new battery standby for photographing. I have numbered the batteries, so I always have alternately in use. Typically, a battery for approximately 200 shots enough. That was a good buy.
