소니 NP-FZ100 충전식 리튬 이온 배터리

Took it out for a full day of shooting on my a7 III and the 2280mAh capacity meant I never even thought about swapping batteries once. Charged it back up in about two hours flat, which is way faster than I expected for a 7.2V pack. Solid investment if you're tired of carrying spares.

Shooting a wedding on my a7 III, this battery outlasted two spares I brought from my old setup, and the 2280mAh charge held up through over a thousand frames without a hiccup. It's the one I grab first now, and it's become the standard I measure everything else against.

The 2280mAh capacity actually shows up in real use—I shot over 1,200 frames across two days on a single charge with my a7 III and never saw the warning light. It's the first battery that makes me comfortable leaving the charger at home.
