8× Zoom, 40m Waterproof, 4K60: A Deep Dive into Yolansin’s Action Cam

A messy blend of ambition and shortcuts that could thrill budget thrill-seekers—and leave focus junkies frustrated.

Why it caught our eye

On paper, this Yolansin action camera is loaded: 4K60fps, a responsive touchscreen, 8× digital zoom, 6‑axis stabilization and a waterproof case rated for 40 m. It ships with two 1350 mAh batteries, a 64 GB microSD card and a handful of mounts. For under a modest budget (no sticker-shock here), it sounds like the perfect sidekick for shredding snow, diving reefs or strapping to a mountain bike.

But when you mix ambition with cost-cutting, something’s got to give. Here’s where it shines—and where it faceplants—so you actually know if it deserves a spot in your gear bag.

Design and durability

This chunk of black plastic feels solid enough to toss in a backpack or helmet mount. The housing clicks shut firmly, and the rugged shells really do shrug off bumps and scrapes—your inflatable raft mishaps won’t kill it. Yet the rubber gaskets have a cheap scent right out of the box, and if you ignore that smell for long, you’ll start worrying what chemicals are diving alongside you.

Pros:

• Solid-feeling buttons on the waterproof case
• Multiple attachment points and clips included
• Feels tougher than foam-core gimbals after a few slams

Cons:

• Waterproof seal needs a careful fit; misalign it once and you risk a leak
• Plastic hinge on the back door flexes oddly after a dozen clips
• Chemical stench lingers around the housing gasket

4K video and photo performance

Bursting with 4K60fps, this camera serves up crisp colors in broad daylight. Wide-angle lenses stretch your frames out to about 170°, perfect for capturing entire valleys or surf breaks. Photo mode tops out at 20 MP—enough detail to blow up your wall poster if you don’t pixel-peep.

Where it falters is in low light or high-contrast scenes. Shadows swallow detail, and highlights can clip with zero warning. The auto-exposure algorithm feels either sluggish or hyperactive—expect a sudden brightness shift mid-ride as it hunts for the right balance.

Quick take:

• Daylight: vivid, pin-sharp footage
• Dusk/dawn: noisy, mushy shadows
• HDR mode: non-existent, so glare from water and snow can blow out highlights

Digital zoom and focus quirks

The big selling point is “8× zoom.” In reality it’s all digital, so you’re cropping pixels, not bending glass. Full-wide at 4K60 looks lovely; zoomed-in at max feels like you squinted through fogged goggles.

Focus is fixed at a mid-range sweet spot. Anything too close (under a foot) or too far (beyond 20 m) sneaks into fuzzy territory. The one review calling it “garbage” was onto something—when you zoom in on a jet ski or a mountain peak, details turn to mush fast.

Key warnings:

• 8× zoom kills sharpness after about 3× digital magnification
• No manual focus or focus tracking—what you see is what you get
• Edge softness and pixelation ruled the day during a recent forest hike

Stabilization in real life

The 6‑axis image stabilization is a solid attempt at smoothing out jostles. On a motorcycle, side-by-side or skate ramp, footage holds together much better than non-stabilized budget cams. But there’s a caveat: at 4K60, stabilization crops in aggressively, so your field of view shrinks to a weird box within the frame.

If you switch to 1080p, you get less crop but more visible shake. At 30 fps, it’s passable for mellow runs, but carve hard and you’ll spot micro jitters and judder.

What you need to know:

• 4K60 = heavy crop + buttery smooth motion
• 1080p30 = wider angle + noticeable shake under intense squeeze
• Stabilization lip-sync with audio is off by a few frames

Underwater feats and potential leaks

The waterproof housing claims 40 m depth—great for freediving or snorkeling. If you properly seal the case, it’s rock-solid down to about 20 m, but push beyond that without double-checking the gasket and you might end up with a watery grave for your card.

Colors underwater need post-processing. Green and blue casts dominate unless you slap on a red filter or push white balance far into drama-land. Still, your reef selfies will pop once you spend ten minutes in Lightroom or your go-to app.

Underwater checklist:

• Always clean seals of sand/grit before closing
• Aperture is fixed at wide-open; fast-moving fish can blur
• Audio is drowned out by housing noise—don’t expect usable sound clips

Battery life and accessory overload

Two 1350 mAh batteries get you roughly 45–60 minutes each at 4K60, closer to 30 minutes if you have Wi‑Fi blasting away. The charger doubles as a USB card reader, which is neat until it jams or refuses to eject the SD card smoothly.

The included 64 GB card is decent but not speedy—file transfers over USB 2.0 drag, and Wi‑Fi export feels like watching paint dry. The remote control works, but it drops signal if you go much beyond ten feet or lose line of sight.

Pro tips:

• Carry a spare microSD rated U3 to dodge transfer slowdowns
• Disable Wi‑Fi unless you really need it
• Buy another charger—this one gets finicky after repeated unplugging

Touchscreen, remote, and wireless

That 2” IPS screen is crisp, but the touchscreen can be unresponsive with wet fingers or gloves. Expect trial-and-error taps to start recording or change modes. The remote is handy for helmet mounts, but its single button means you can’t toggle through every mode—just record/stop and snap photos.

Wi‑Fi pairing happened smoothly on Android, but the iOS app crashed twice mid-download. Streaming a live view to your phone works until the connection hiccups and the app forces you to restart the session.

What’s clunky:

• Swipe-to-review is sluggish and often ghost-taps
• No haptic or audio cue when you actually hit record
• Wi‑Fi kills battery life within minutes if you leave it on

The stink test and other red flags

One user called it “absolute trash,” complaining of chemical fumes, zero focus and worthless 4K. That echoes the cheap-o rubber smell and the lens softness under tight zoom. You won’t wreck your wallet, but you might lose your patience.

If you prize impeccable focus, pro-level audio, or rock-solid zoom optics, this camera will drive you nuts. It’s a rugged toy for hobbyists who can forgive glitches and throw on stabilization in post. Professionals, steer clear.

Red flags summary:

• Persistent chemical odor from the waterproof housing
• Digital zoom + fixed focus = soft, noisy footage at high magnification
• Flimsy touchscreen under moisture or cold gloves

Is it your next adventure buddy?

If you’re chasing a cheap thrill—4K clips for YouTube, social media stories, GoPro-style helmet shots—this Yolansin camera will do the trick. It’s like that scrappy friend who jumps into every wild activity without overthinking safety gear.

But if you need razor‑sharp zoom, perfect low-light performance or pro audio, look elsewhere. Spend a bit more for glass optics, genuine manual controls and a housing that smells like nothing but victory.

Bottom line: for backpackers, casual divers and social-media cowboys who just want funky POV shots and don’t mind a little fuzz around the edges, this camera is a fun sidekick. If you can’t tolerate its digital zoom haze or its gadget quirks, it’s time to shop upmarket.

Gear up, stay wild and let your footage do the talking—just maybe not at 8× zoom.
