◆ opening & exterior check
Xiaomi's action camera Yi's second generation model "Yi II" is in a white dressing box.
When opening the box Yi II appears.
Inside the lid, a sponge-like cushioning material was affixed so as not to damage the lens.
The contents are Yi II main body, battery, Micro-USB cable for charging, simple instruction.

Also peel off the protective film of the LCD monitor.
Yi II is a design that fully traced "GoPro HERO" series which is a synonym for action cameras. The lens with the F value of 2.8 has popped out, and it is the same as GoPro until it is easily scratched. The size is 42 mm in length × 65 mm in width × 21 mm in depth, and weighs 95 g.
On the top is a speaker, two microphones, a power / shoot button.
There is no button like GoPro on the front side with the lens. As the sensor adopts Sony made IMX 377, Yi II can shoot 4 K (3840 × 2160) movies as indicated by "4 K". Indicator LED indicating the shooting situation is carried to the left of the print notation.
On the right side is a Micro - USB port for power supply. The GoPro HERO 4 series is a relatively minor mini-USB port, while the later Yi II is convenient because it can use the widely spread Micro-USB cable.
There is nothing on the left side.
Remove the battery from the bottom. There are also screws for a tripod.
Sliding in the horizontal direction to release the cover is the same style as GoPro.
The microSD card slot is carried inside.
The battery is 1400 mAh. Because the rival's GoPro is 1160 mAh, the capacity is larger for Yi II.
Even with the battery loaded, it was possible to insert / remove the microSD card.
The liquid crystal display is 2.19 inches (640 × 360) and the aspect ratio is 16: 9.
◆ Compare the appearance with GoPro
I will compare it with GoPro HERO 4 which will be a competitor.
Compared to GoPro HERO 4, Yi II has a lateral width.
The thickness (depth) is almost the same.
Mount a liquid crystal displayGoPro HERO 4 Silver EditionCompare the rear display with this feeling. The liquid crystal display feels quite large for Yi II.
The difference in size is clear when you switch to shooting mode. In high-definition movie shooting, I often use 16: 9 aspect ratio, so I feel that Yi II is bigger than the size difference of the liquid crystal display and it is easier to check the shot movies.
◆ I tried using
You can touch Yi II by touching the liquid crystal display except turn on the power and start / end shooting with the button on the top. The user-friendliness of Yi II by touch operation can be understood with a single shot when looking at the following movie.

Not only the touch responsiveness and handling processor but also simple and easy to use UI improves the usability of Yi II. In the GoPro HERO 4 series, even though the UI such as the "HERO 4 black edition" model which does not have liquid crystal is sometimes not intuitive, it may be difficult to use, but the operability between Yi II and GoPro without a liquid crystal monitor is the difference of muddy, clearly Saying that this ease of use alone seems to be worth changing from the GoPro series.
· 4K movie
Yi II can shoot movies of 4K (3840 × 2160, maximum 30 fps). I tried how much the 4K image quality of the low price action camera below 30,000 yen is. In addition, in order to play at 4K picture quality, you can change the picture quality of YouTube to "2160p".

Of course, I could shoot a 4K movie without collapse without dropping frames. The body does not generate so much heat, there is no indication of thermal runaway at all. As long as the capacity of the microSD card has, you can enjoy 4K movies.
Although it is a beautiful 4K movie just as high definition, I tried to shoot 4K · 30 fps movies simultaneously using GoPro's high end model "GoPro HERO 4 black edition" and check the difference in picture quality with Yi II. In addition, the movie is Yi II on the left and HERO 4 black edition on the right, using Yi II's audio.

Of course, Yi II supports many formats such as 2.5K (2560 × 1920), 1440p (1920 × 1440), 1080p (1920 × 1080), 720p (1280 × 720) other than 4K. I tried to check GoPro HERO 4 silver edition and image quality using the setting of 1080p (1920 × 1080) · 60 fps as the most common image quality. The movie is Yi II on the left and HERO 4 Silver Edition on the right, using Yi II's audio.

Under the setting of full auto all, it feels like Brilliant HERO 4 Silver Edition against the natural color Yi II. However, since GoPro has sky skipping in the sky, Yi II seems to be said to be a safe seasoning.
Yi II has a slow motion mode that can shoot at 200 fps with 720p (1280 × 720) and 480p (848 × 480). In the slow motion mode at 720p, you can easily shoot the following movies.

Xiaomi Yi II realizes the price of about half the price of about 250 yen for the HERO 4 black edition with the list price of 499 dollars, while having camera performance qualitatively as GoPro HERO 4 black edition. Moreover, it is also capable of shooting 4K movies at 15 fps, even with HERO 4 Silver Edition as well as a touch-enabled LCD monitor, and also supports shooting 4 K · 30 fps over HERO 4 Silver Edition, GoPro HERO 4 series It seems to be said that it is totally taking in the good part of it.
Although it seems that GoPro is leading the moment at the point that it has abundant accessories and built-in dedicated software such as housing, Xiaomi's Yi II which realizes equivalent high performance at half price, is powerful It seems to show its presence in the action camera market as a rival.
