Sony NP-FW50 battery holder for A6000 A6500 A6400 A6300 A7 AA7SII A7S A7R RX10 (4 Batteries)

Not for A7III! Batteries not included. Sony's A7 cameras certainly go through batteries. They all use the NP-FW50 batteries which are small and light - but you need to carry quite a lot of them around on a day's shoot. This is a simple holder for however many batteries you need!. You can insert the batteries terminal "out" or "in" and this can provide you a signal for which are charged, which are discharged.
