Sony a1 II Sony a1 II
The Sony a1 II is a 50.1 MP (still image shooting) full frame camera for Sony E-mount lenses that weighs 658 g without battery or card, shoots up to 30 fps (electronic shutter, Hi+ mode) and records 8K 30p video. Next to 21 other Sony E-mount full frame cameras, it suits you if you crop hard or print big, you film as much as you photograph, or you shoot sport, wildlife or children. If you carry it all day or travel light, every other one that does better on weight gives up burst speed.

- Lead for a pick1
Our pick or our take adds up the importance of each real difference, with these importances and thresholds: a gap smaller than its row's threshold is too close to call and counts as the same. They are our editorial choice, not a measurement, the same on every page, and they never read prices, sales or who sells it.
