Nikon Keymission 170 4K Action Camera Specs Unveiled

Imagine you’re hiking a steep mountain trail, camera in hand, capturing the golden sunrise over a sea of clouds. You want every detail sharp, every color vibrant, and every movement smooth. That’s where the Nikon Keymission 170 4K action camera steps in. It’s not just another gadget on the shelf—it’s a rugged, compact companion built for adventurers, travelers, and content creators who demand high-quality footage without the bulk.

When Nikon first announced the KeyMission series, the 170 model stood out with its promise of 4K recording, built-in stabilization, and waterproof design—all in a tiny, go-anywhere package. But specs alone don’t tell the full story. As someone who’s tested action cameras from GoPro, DJI, and Sony, I was curious: Can Nikon, a brand known for DSLRs and photography excellence, truly compete in the fast-paced world of action cams? After weeks of using the KeyMission 170 on trails, in pools, and during urban vlogging, I’m ready to unpack everything you need to know—its real-world performance, quirks, and how its specs translate into everyday use.

Design and Build: Built for the Elements

The first thing you’ll notice about the Nikon KeyMission 170 is its compact, no-nonsense design. It’s small enough to fit in a pocket, yet feels solid and well-built. Unlike many action cameras that require bulky external housings for waterproofing, the 170 is waterproof up to 30 meters (100 feet) right out of the box. That’s a huge win for divers, snorkelers, and anyone who hates fumbling with extra cases.

Size, Weight, and Portability

Measuring just 65.5 x 45.9 x 42.5 mm and weighing 134 grams (with battery and microSD card), the KeyMission 170 is lighter than a smartphone. I clipped it to my backpack strap during a weekend hike, and it didn’t bounce or snag—even on rough terrain. The smooth, rounded edges make it comfortable to grip, and the rubberized coating adds a bit of grip, though it’s not as grippy as some competitors with textured surfaces.

One small but smart design choice: the lens sits slightly recessed, protecting it from scratches when placed on surfaces. It’s a simple touch, but it shows Nikon thought about real-world use.

Durability and Weather Resistance

Beyond waterproofing, the camera is shockproof from drops up to 2 meters and freezeproof down to -10°C (14°F). I accidentally dropped it from a table onto a wooden floor—no scratches, no issues. I also used it during a rainy forest trek. The lens stayed clear, and the buttons worked smoothly, even when wet.

That said, the microSD card and USB port are covered by a small rubber flap. While it’s secure, it can be fiddly with cold fingers or gloves. A magnetic or sliding cover, like on some newer models, would’ve been easier.

Pro tip: Always double-check that the flap is fully sealed before submerging. A tiny gap could let in water—something I learned after a close call during a kayaking trip.

Button Layout and Controls

The 170 has three physical buttons: power/record, mode, and Wi-Fi. The power button doubles as the shutter for photos, and a long press starts video recording. It’s intuitive, but the buttons are flush with the body, so they’re hard to press with gloves or wet hands. I found myself using the Nikon KeyMission app more often for remote control—especially when the camera was mounted on a helmet or bike.

The lack of a touchscreen might seem outdated, but it’s a smart move for an action camera. Touchscreens don’t work well underwater or with wet fingers, and they drain battery. Physical buttons are more reliable in extreme conditions.

Video and Photo Performance: 4K That Delivers

The heart of any action camera is its image quality. The KeyMission 170 shoots 4K UHD video at 30fps, 1080p at up to 60fps, and 720p at 120fps for slow motion. It also captures 8.3MP still photos. But specs are just numbers—what matters is how they look in real life.

4K Video Quality and Color Science

4K footage from the 170 is crisp, with good detail and natural colors. Nikon’s color science leans toward realism—less saturated than GoPro’s “poppy” look, which I actually prefer for travel vlogging. Skin tones look natural, and greens and blues in landscapes aren’t overly boosted.

In bright daylight, the camera performs exceptionally well. I filmed a sunrise hike, and the transition from dark shadows to bright highlights was smooth, with minimal blown-out skies. The dynamic range isn’t as wide as high-end mirrorless cameras, but for an action cam, it’s impressive.

Low-light performance is where it struggles. In dim indoor lighting or at dusk, noise becomes noticeable, and colors lose vibrancy. It’s not terrible, but don’t expect DSLR-like quality. For night shots, stick to well-lit areas or use an external light.

Stabilization and Field of View

The KeyMission 170 has a 170-degree ultra-wide-angle lens—hence the name. That’s wider than most action cams (GoPro Hero 7 is 120°, for example), which means more scenery in every frame. It’s great for immersive POV shots, like skiing or cycling.

But wide angles can create a “fisheye” effect. The 170 uses electronic stabilization (EIS) to reduce shake and correct distortion. In my tests, it worked well for walking and light running. On a mountain bike, the footage was smoother than I expected, though there was still some wobble in fast turns.

One limitation: EIS crops the frame slightly, so the effective field of view is closer to 150° when stabilization is on. That’s still wide, but not the full 170°.

Slow Motion and Time-Lapse

The 120fps 720p slow motion is fun for action shots—think splashing water or a skateboard trick. It’s not 1080p, but the quality is decent, and the slow-mo effect is dramatic. I used it to film my dog jumping into a lake, and the details were clear.

Time-lapse mode is simple: set the interval (1, 2, 5, 10, 30, or 60 seconds) and duration. I created a 5-minute sunset time-lapse by setting it to 5-second intervals for an hour. The result was smooth and cinematic, though the camera gets warm during long sessions—keep it ventilated.

Audio, Connectivity, and Accessories

Great video needs great sound. The KeyMission 170 has a built-in stereo microphone, but audio quality is a mixed bag. Let’s break it down.

Built-in Microphone Performance

In quiet environments, the mic captures clear voice audio. I recorded a voiceover while sitting in a park, and my voice came through naturally. But in windy conditions, the mic struggles. Even a light breeze creates a low rumble, and strong winds drown out voices completely.

Tip: Use a windscreen (sold separately) or mount the camera close to your body to reduce wind noise. For vlogging, consider an external mic via the 3.5mm jack—though this requires a separate housing, as the port isn’t accessible in the standard waterproof design.

Wi-Fi, Bluetooth, and App Integration

The camera connects to the Nikon KeyMission app (iOS and Android) via Wi-Fi and Bluetooth. The app lets you control the camera remotely, preview footage, and transfer files. It’s user-friendly, with a clean interface, but the Wi-Fi range is limited to about 10 meters. Beyond that, the connection drops.

Bluetooth is used for quick pairing and GPS tagging (if your phone has GPS). It’s reliable, but don’t expect long-range control. For helmet or bike mounts, keep your phone nearby.

File transfer speeds are decent—about 2-3 minutes for a 4K video—but not as fast as newer Wi-Fi 6 standards. If you’re shooting a lot, consider removing the microSD card and using a card reader.

Accessories and Mounting Options

Nikon offers a range of mounts, including helmet, chest, and handlebar options. They’re sturdy and easy to use, though some feel less premium than GoPro’s mounts. The 170 uses a standard GoPro-style mount, so third-party accessories (like suction cups or tripod adapters) work perfectly.

I used a chest mount for hiking and a handlebar mount for cycling. Both held securely, even on bumpy trails. One downside: the camera’s shape makes it wobble slightly on some mounts. A rubberized base or tighter fit would help.

For underwater use, Nikon offers a dive case for depths beyond 30 meters. It’s well-built, with clear glass for the lens, but it adds bulk. If you’re a casual snorkeler, the built-in waterproofing is enough.

Battery Life and Storage: What to Expect

Battery life is a common concern with action cameras. The KeyMission 170 uses a removable 1400mAh EN-EL12 battery, which Nikon claims lasts up to 85 minutes of 4K recording.

Real-World Battery Performance

In my tests, I got about 70-75 minutes of 4K recording at room temperature. In cold weather (around 0°C), that dropped to 50-60 minutes. Wi-Fi and stabilization also drain the battery faster. For a full day of shooting, I’d recommend carrying a spare battery.

The battery charges via USB-C, which is fast and convenient. A full charge takes about 2.5 hours. The camera can also be powered by a USB power bank—great for long hikes or time-lapses.

Storage and Memory Card Recommendations

The 170 supports microSD cards up to 128GB (UHS-I U3 or higher recommended). A 64GB card holds about 80 minutes of 4K video or 1,500 photos. I used a 64GB SanDisk Extreme, and it worked flawlessly.

One quirk: the camera doesn’t have internal storage, so you must insert a card before recording. It’s a minor annoyance, but worth noting if you’re used to phones with built-in storage.

Tip: Format the card in-camera for best performance. I once used a card from another device, and the camera froze—reformatting fixed it.

Comparisons and Who Should Buy It?

How does the KeyMission 170 stack up against competitors? Let’s compare it to the GoPro Hero 7 Black and DJI Osmo Action—two of its closest rivals at launch.

Nikon vs. GoPro Hero 7 Black

Video: Both shoot 4K30, but GoPro has better stabilization (HyperSmooth) and higher frame rates (1080p120 vs. 720p120).
Waterproofing: GoPro needs a housing for 10m depth; Nikon is waterproof to 30m out of the box.
App: GoPro’s Quik app is more polished, with better editing tools.
Price: The 170 was slightly cheaper at launch, offering better value for budget-conscious buyers.

Verdict: If you prioritize stabilization and editing, go GoPro. If you want hassle-free waterproofing and Nikon’s color science, the 170 is a solid choice.
