Nikon KeyMission 170 & 80

In January Nikon announced the KeyMission 360, and now it’s adding a further two action cameras to the range. The new KeyMission 170 – named to reflect its 170-degree field of view – boasts an f/2.8 lens and an 8.3MP, 1/2.3-inch CMOS sensor capable of capturing 4K UHD or 1080p Full HD video, as well as stills.

Useful action-orientated extras include slow motion movie capture, time-lapse and loop recording functions, as well as a Highlight Tag feature that enables you to create a montage of stand-out moments. Like the KeyMission 360, the 170 is shock-proof from two metres and freezeproof down to -10 degrees Celsius, although its 10-metre waterproof rating is no match for the 360’s 30-metre resistance. That said, an optional underwater housing enables dives down to 40 metres.

If the KeyMission 170’s 66.4 x 46.8mm x 42.7mm size isn’t quite portable enough, enter the KeyMission 80. This wearable action cam is just 15mm thick and a featherweight 74g, yet it packs a 12.4MP f/2 front-facing camera with an 80-degree field-of-view, plus a 4.9MP f/2.2 rear-facing selfie cam.

The 80 is also freezeproof down to -10, though shock resistance is a more modest 1.5-metres and it’s only waterproof to 1 metre. Despite boasting a higher resolution than the KeyMission 170, the 80 will only capture 1080p Full HD video, but it’s not short on features: there’s time-lapse and interval timer modes to capture longer journeys, and everything’s controlled using a touch-sensitive LCD. As with the 170, Nikon has incorporated its SnapBridge tech for easy real-time sharing to smart devices. First impressions_

Nikon may have been late to the action camera party, but these new models look like compelling contenders.
