New releases

Since initially publishing our 4K action camera roundup several new models have been released at Photokina 2016 including the GoPro HERO5 Black (and Session), Sony X3000 and Nikon KeyMission 170 (we've also added the Garmin VIRB Ultra 30). We'll update this roundup as soon as we've had a chance to assess each, for now, key info and stand-out features can be found below:

GoPro HERO5 Black

The GoPro HERO5 Black is the company's new flagship action camera. It's waterproof down to 33 feet without the need for housing and is 4K-capable (at up to 30 fps). Like its predecessor it uses a 1/2.3" sensor and is capable of 12MP still images in JPEG and now Raw, as well. The unit has a 2" touchscreen, a range of voice activated controls, GPS, 3 microphones and electronic stabilization in 1080p. It's priced at $399.

GoPro HERO5 Session

With nearly identical specifications to the flagship HERO5, the session is a smaller 4K option, skipping the touchscreen which results in a very small, cube-like form factor (we were big fans of its predecessor, the HERO4 Session). It's priced at $299.

Nikon KeyMission 170

The KeyMission 170 is Nikon's first real jump into the traditional action camera market. Waterproof to 33 feet without the need for a case, the KeyMission does 4K/30P video. It also uses a 12MP 1/2.3" sensor and features a built-in LCD (non-touch), stereo mic, and tripod socket. It uses the same Nikon EN-EL12 battery as many of the company's compact cameras. Electronic image stabilization is offered at 1080/120p. The KeyMission 170 will set you back $399.

Sony FDR-X3000

The X3000 is the latest top-end action cam from Sony and it has a lot of promise. Neither waterproof nor shockproof unless you use a case, this camera's big selling point is optical image stabilization in 4K video, something none of its competitors offer. The X3000 uses a 8.2MP 1/2.3" BSI-CMOS sensor with full sensor readout and no pixel binning. It is 4K/30p capable, feature a new user interface (thank god) and a smaller design compared to previous models. It also features a new Zeiss lens design and retains its tripod thread. You can pick an X3000 up for yourself at a price of $399.

Garmin VIRB Ultra 30

Announced in late August, the VIRB Ultra 30 is a surprisingly feature-packed 4K-capable option. Like the GoPro HERO5 Black, it offers voice controls, a GPS and a touch-sensitive display. It also has a barometer, accelerometer, compass and gyroscope. Capable of 4K/30p video capture, the unit makes use of a 12MP sensor (likely 1/2.3").  It is not waterproof without a case though. And while it offers electronic image stabilization, like its competitors (excluding the Sony) it can't be turned on during 4K capture (it can be used at up to 1440/60p though). The VIRB Ultra 30 is one of the pricier 4K options coming in at $499.
