The GoPro HERO12 Black was released in September 2012. It’s a relatively modest upgrade over the HERO11 Black and keeps compatibility with most of the same accessories and mounts as the HERO10 Black and HERO11 Black.
It uses the same GP2 chip and retains the same-size sensor, has improved runtimes thanks to more efficient power management, adds HDR Video (up to 5.3K30), upgrades HyperSmooth to 6.0, adds support for Bluetooth mics, better support for vertical shooting, new GP-Log video for capturing increased dynamic range, and adds compatibility with the new Max Lens Mod 2.0 for 177° field of view in 4K60 video.
The HERO12 Black does not have GPS. That feature, which has been a staple of many previous versions of GoPro cameras, has been left off this one.
