Sony announced two new APS-C mirrorless interchangeable lens cameras at a special event in New York today, and the announcements are big news for anyone who’s looking for a small, capable camera that can handle everything from sport shooting to vlogging. The new a6600 flagship takes everything that is great about the a6400 it introduced earlier this year, and adds a big battery boost, in-body stabilization, a headphone jack and real-time eye autofocus for video.

The a6600 otherwise looks nearly identical to the a6400 on paper – it has the same 24.2 megapixel APS-C sensor, ISO sensitivity that expands all the way up to 102400, burst shooting at up to 11 fps, 3k 40p internal HDR recording and the same quality viewfinder. None of that is in any way a criticism, however – these were all excellent specs when they debuted on the a6400 earlier this year, and they’ll serve a6600 owners just as well.
