If you don’t mind your wearable action cam being tethered to a separate unit for wrangling controls, Panasonic’s HX-A500 offers 4K video capture in return. The company touts the camera as the “world’s first” option for said resolution, recording the those exploits at 25fps. There’s also a 1080p option at 50fps, 720p at 100fps and 480p an a 100fps crawl for judging that swing in time for baseball season. It will also capture up to 30 minutes of video in up to three meters (about 10 feet) of water, should the need arise. Need to get the footage to another device? NFC and WiFi connectivity are built in with compatibility with Ustream for live broadcasts.
