From a usage perspective, I found the KeyMission 170 very comfortable to use, and once I had figured out how to get SnapBridge working, the user experience is very good. I liked using it much more than my GoPro. In a firmware update, I would like to see Nikon add the exposure control and correction.

Easy to use; Compact; Build quality; Battery life; Screen size

If you're on the hunt for a new action camera, you've probably realized that there are a ton of great option for you. Many of the industry leaders, particularly GoPro, have gone for a "one size fits all" approach by releasing a singular model that is designed to do it all.

Easy to use software but some flaw: you can't use the camere while plugged in charge and you have to remove the battery or the charge will fall to zero in a few days even if the camera is turned off.

Having a couple of Nikon DSLR cameras I thought I would give their Keymission 170 a go instead of a GoPro. Extremely disappointed, not the usual quality of other Nikon products. On opening the box, immediate reaction was that the accessories were not as robust as they should be for an action camera...

I recieved this last week was really impressed by built quality set it up, menu system on camera not great / tried to connect it to my two smart devices (different makes) this is where Nikon has let this camera down nightmare to use returned item should have got a GOPRO

Tough well made camera waterproof. Lots of options for shooting good action video and stills pictures.Camera works smoothly through its options giveing good results. 4K video Slowmotion and standard settings.

I bought this camera on release as i am a huge Nikon fan. I wanted a action camera to take scuba diving with me and GO PRO had not announced the 5 yet(still would not have bought it if they did).

At the moment the price of Nikon KeyMission 170 is about $399.99. It is quite expensive, but GoPro costs no less. Moreover, Nikon action camera offers better picture, accessories in the kit, the control panel.

This is awful junk . The remote control is just cheap rubbish and nine times out of ten doesn't work. The stand is shakey and connects badly, and the covers etc on the camera look like they'll be water proof for all of about ten minutes. The depth (10m) limit is also pathetic.

As yet we've been unable to use a full production model of the KeyMission 170, but we think that it should be capable of producing decent images. We saw some early footage at Photokina, and it looks like it could be a good addition to the burgeoning action-camera market.
