Yi Discovery Motion Digital camera assessment

Sixty bucks (or kilos). That is how a lot Chinese language corporate Yi is charging for its newest funds motion digital camera. And you recognize what? It is beautiful excellent.

Yi has been on a project to undercut GoPro for some time, issuing a couple of funds motion cameras just like the Yi 4K. Alternatively, now it is undercutting itself through taking its already excellent price Yi Lite and slashing a couple of options to create this new model, the Yi Discovery.

The accessory-laden Yi Discovery Motion Digital camera with Accent Equipment package sells for £59.99 / $59.89, whilst the Yi Discovery Digital camera pack (which incorporates most effective the digital camera, a micro USB cable and a battery) sells for a trifling £42.99. Whilst the previous bundle is aimed on the newbie, the latter is explicitly for the ‘backup’ motion digital camera marketplace. Do not need to harm your GoPro on a specifically bold shot? So purchase a standalone Yi Discovery and rattling the effects! It is a novel gross sales tactic, however at this low worth, it could simply paintings.


  • 4K video seize restricted to 15/20fps
  • Smaller battery than Yi Discovery
  • First rate package of accessories

This motion digital camera does 4K. Taking into consideration its super-low worth, that is outstanding, even supposing it’s restricted to 4K at 15/20 frames in step with 2nd (fps) – 15fps for NTSC, 20fps for PAL. It additionally motion pictures in lesser video qualities to avoid wasting area, particularly 1440p/25 or 30fps, Complete HD 1080p/60 or 50fps and HD 720p/90 of 75fps. It saves them as H.264/MP4 recordsdata.

The sensor is unchanged; the Yi Discovery has a Sony MX179 symbol sensor in a position to 8MP nonetheless footage (which it upscales to 16MP), and a 150° wide-angle, mounted focal point lens with an aperture of f/2.four. Now not so the rechargeable lithium battery, which is much less spectacular; simply 900mAh in comparison to the Yi Lite’s 1200 mAh. Nonetheless, there are two of them within the field. Yi guarantees 110 mins battery lifestyles for Complete HD 1080p, and 75 mins should you shoot the whole thing in 4K.

The contents of the field is spectacular. Within the accent equipment we examined there was once an underwater casing excellent for a 40m dive, two batteries, a chest strap, a suction mount, a motorbike handlebars mount, and a lot extra.

The Yi Discovery additionally has a 2.4GHz Wi-Fi module. Now not the 5GHz choice at the Yi Lite, however regardless of. The app that controls it remotely, and exchanges recordsdata with a phone, is unchanged; that Yi Motion app hyperlinks simply to a phone and transfers video and stills with out fuss, even though it does downscale 4K movies to Complete HD when it sends them to a phone. It is then simple to add photos to social media and YouTube from throughout the Yi Motion app.

The tool at the Yi Discovery is strictly the similar with all different fashions, too, so it contains complicated options like burst mode, a timer mode for workforce pictures, slow-motion, time-lapse, and loop document.

The Yi Discovery does no longer really feel like the inexpensive acquire it’s. The packaging is unfussy, however excellent high quality, it is all packed smartly, and the product itself is sort of precisely the similar as different pricier Yi merchandise. In a marketplace saturated through cheap-looking merchandise, the cast Yi Discovery is an exception.

It makes use of virtually precisely the similar 65x42x30mm chassis because the Yi Lite, weighs an an identical 72g, and has the similar measurement LCD display. In follow, there’s a distinction within the high quality of the touchscreen, which is much less delicate, and infrequently jumps round all the way through navigation. Alternatively, the most important disgrace in regards to the Yi Discovery’s elementary design is its loss of integrated tripod thread. That makes it not possible to mount on a tripod or selfie stick with out first delving into that huge selection of accessories. For some customers, that shall be a big blow, as smartly the loss of local waterproofing.

Whilst at the Yi Lite there’a a robust battery duvet that still features a microSD card slot, at the Yi Discovery there is a some distance much less considerable duvet, with a 16-64GB microSD card slot and micro USB charging slot, located at the aspect, and left open to the weather.


  • In a position to easy HD 
  • Now not at its easiest when in 4K mode
  • Yi Discovery isn’t that fab in low-light

In a position to easy HD and applicable 4K video, this funds Complete HD motion plays way past the ‘backup cam’ declare. The Yi Discovery isn’t at its easiest when in 4K mode. The effects are fairly jumpy all the way through digital camera pans and fast transferring pictures, which additionally come with some jagged edges. Alternatively, the 20fps photos in our check displayed a lot of element in blank nonetheless pictures. That’s no longer best for motion photos, however no less than color is easily saturated. So too on Complete HD 1920×1080 video at 50fps, which nonetheless remains to be fairly jumpy all the way through pans, even though has fewer video artefacts. There’s additionally a noticeable drop intimately. That is going double for video shot in 720p 1280×720 solution at 75fps, even though it’s easy and simple to observe. If you happen to’re in search of watchable video of motion sports activities, 720p is the most efficient atmosphere. Body-rates imply that Complete HD 1920×1080 video at 50fps is the best of the 3, using-up not up to part the distance a 4K 20fps report occupies. A 720p 1280×720 solution at 75fps video report is ready a 3rd smaller than 4K 20fps (even though there’s an enormous selection of body charges for the decrease resolutions).

The primary video was once shot in 4K at 20fps, whilst the video above was once shot in Complete HD at 50fps

It’s price citing that the Yi Discovery isn’t that fab in low-light, so it’s easiest utilized in vivid prerequisites.

That still applies for pictures, for which the Yi Discovery impresses. Its Sony IMX179 sensor in reality takes 8 megapixel footage and upscales them to 16 megapixels, and that’s evident should you zoom-in on them. Alternatively, the colour steadiness in some pictures is superb, and the wide-angle proved in point of fact helpful all the way through our check for taking footage of enormous, looming Georgian structures of Edinburgh’s new the city. It’s a set focal point fisheye lens, so vertical edges generally tend to bend and there may be some chromatic aberration within the corners of the body. It additionally can pay stay your topics no less than a couple of metres away to permit for picture to be in focal point.

The place it doesn’t examine smartly to the Yi Lite is with boot-up velocity and battery energy; it’s gradual to switch-on, and the battery most effective lasts about 90 mins. So be sure you take that further one alongside.

The Yi Discovery is part the cost of the Yi Lite, and no more than 1 / 4 that of a GoPro. For that saving you do lose options. There is not any GPS, fewer frames are captured in 4K video mode, and neither is it natively water resistant. The battery is smaller, there is not any symbol stabilization, and the chassis omits an built-in tripod thread. Neither is the touchscreen the best.

Alternatively, if you don’t care about any of that – and lots of may not – then the Yi Discovery is price bearing in mind. It will not be the ultimate in motion cameras, however it gives superb high quality stills and Complete HD video, applicable 4K should you stay the digital camera nonetheless, and a simple to make use of interface and app.

The Yi Discovery proves an excellent back-up and a completely excellent price entry-level choice for any person after core options most effective, and at a worth that is in point of fact exhausting to argue with.
