It might have been slightly overshadowed by this morning's grand GoPro launch, but Nikon has used Photokina to add two new models to its lineup of KeyMission action cameras. Alongside the 4K KeyMission 360, which was unveiled at CES earlier this year, there are two new rugged offerings catering to adventurers who don't need 360-degree recording.

KeyMission 360

Even though it's only got two lenses, the box-shaped KeyMission 360 is able to record 4K, 360-degree stills and video. Images from the dual f/2.0 lenses are captured by 20-megapixel CMOS sensors at either 3,840 x 2,160 or 1080p, and automatically stitched together by the in-camera software. The dual lens setup can also be used to capture 30-megapixel stills.

The camera is fully waterproof to 30 m (98 ft) and shockproof to drops of 2 m (6.6 ft), although the -10° C (14° F) freezeproof temperature might not be enough for avid skiers and snowboarders.

Although there's no screen on the camera, it can be connected up to the Nikon SnapBridge app, which acts as a live viewfinder. The app also offers tools for sharing and editing, and works with the KeyMission 360 and 170.

Included in the box is a set of adapters, a base mount and silicon jacket for the camera, along with two lens protectors and a cardboard headset allowing for immersive smartphone playback.

The KeyMission 360 will cost US$499.95 when it lands in stores in October.

KeyMission 170

The KeyMission 170 looks remarkably conventional compared to its dual-lens big brother, but its feature set is still impressive. Its f/2.8 lens and 8.3-megapixel CMOS sensor allow 4K image capture with an ultra-wide 170-degree field of view.

Using the rear screen, users are able to set up their shots with live view, play back previous footage and change settings. Unlike the GoPro Hero4 Silver it's not a touchscreen, but the little rubber buttons will work with gloves on, which can't be said for conventional touch screens.

Just like the 360, the KeyMission 170 is waterproof to 30 m (98 ft) – or 40 m (131 ft) with a housing fitted – shockproof to 2 m (6.6 ft) and freezeproof to -10° C (14° F). It also shares the same smartphone app, although the cheaper 170 doesn't include the same range of mounts and adapters in the box. Prices start at $399.95.

KeyMission 80

The KeyMission 80 isn't quite as clever as its brethren, but that's not really the point here. Using a 12-megapixel CMOS sensor and a 25 mm f/2.0 lens, it can capture 1080/30p HD video with an 80-degree field-of-view. There's also a 5-megapixel, f/2.2 camera attached to the back for selfies.

Nikon has aimed for easy one-handed operation with its design, which is waterproof to 1 m (3.2 ft), shockproof to 1.82 m (6 ft) and freezeproof to -10° C (14° F)

Once users have got their footage and photos on board, they can be shared with a smartphone using Nikon SnapBridge software. Although it's not compatible with the same app as the 170 and 360, the cheapest KeyMission does boast touch control from its 1.75-in screen. You'll pay $279.95 when it hits stores in October.

All three cameras launched at Photokina, which runs until September 25.
