Sony A9 II review

The Sony A9 II is the fastest, most ferocious full-frame sports camera we’ve ever used. Its blistering speed and autofocus performance are matched only by its phenomenal connectivity, which promises to be a game changer for pro shooters. We would love to have seen Sony implement something akin to Olympus’ Pro Capture feature, so that you never miss the critical moment. However, if our most damning criticism is that the A9 II is too fast for us to keep up with, surely that’s nothing but mission accomplished for Sony!

Sony A9 II Review

The new Sony Alpha A9 II is faster, more refined, more durable and more versatile than the two-year-old A9 camera that it succeeds, making it simply a better tool for the professional sports photographers and photojournalists that it’s even more clearly aimed at.
