Ultimately, your choice in action camera should come down to performance and ease of use. We've filmed hours of footage with many of the major contenders to determine where each device stands in the field. Some excel in all manner of extreme situations, while others can fall apart underwater or once the sun goes down. And what good is an action cam if it's not built for action? The Sony A6500 and A6400 are Sony’s top-of-the-line cropped sensor mirrorless cameras. They feature a 24MP APS-C CMOS sensor and records UHD 4K up to 30fps. The Sony A6500 offers many of the same pro-level features characteristic of Sony’s a7 series cameras, such as 5-axis image stabilization and S-Log picture profiles. The Sony A6400 offers the capability of shooting with hybrid log gamma, and an improved color science from the A6300 and A6500. Thanks to the smaller sensor, however, both cameras come at a much lower price point than the full frame a7 series.
Then there's resolution and video quality. You'll want a camera that can record in 4K for sure. The top-end models from DJI and GoPro offer 60fps 4K with digital stabilization that's absolutely incredible. They're also not limited to ultra-wide views; you can set a narrower angle to remove lens distortion, making them solid choices for vlogging and travel logs.
