[lock1]

rolled out the full specifications for the new Yi 4K +
off site

Based on the figures, I don’t see the point of updating the camera yet: I only use 4K for shooting panoramas, etc. and subsequent downscaling.
1080 also shoots, less battery life, photos in the same resolutions, voice control is a PPC marketing infection that goupro everyone will infect like ...

Another thing is if after the release and viewing of real reviews it turns out that the sores of the flimsy case have been cured, the coating itself will not be glossy but will feel more solid, will correct the tendency to overexposure in auto mode (well, the picture in general) ...

In general, we will wait without release for the release.

It seems like they promised support for external microphones

[shelline]

[email protected], 16:47

Based on the figures, it’s impossible to update the camera yet:

One thing is distressing that in our version the microphone cannot be attached to an external one, although there were rumors in the early stages.

voice control is gut marketing infection which goupro everyone will infect like ...

I agree! Especially when the camera is in the box, try to tell her something ... :)))

But an external microphone is the right thing!

For this price, I suppose, the number of people willing will be greatly diminished ... :)

They leveled prices with Gopro 5, which is now 32 thousand. For such money, the client has the right to demand the Russian language and the normal support of the goods, including the exchange of repairs and so on. Otherwise there is no point.

Well 27 tr. The price is adequate ... xiaomi always starts to make all the new items on pre-order, that is, without investing. They cooked a model and offered it to the market ... such a policy. Actually the price strongly depends on the price of the processor, it is new and expensive.
The decision to start selling yi 4k at the beginning of the year is rather risky (most likely it will be an assessment of the market they have taken in this category, first of all, those who are a fan of yi will take). Since it is much easier to start manufacturing products not the first, since the chips are already cheaper and the market has already been tracked by competitors. So xiaomi holding is taking a risk, but doing it deliberately ... Firstly, gopro will release its "hero 6" only in the fall, and they will already have to lower their prices and at a loss, since GoPro makes their sales starts for real ones money, not through pre-order. Also, with the release of the new camera yi not in the fall, but before the holiday season, it will set the competitive race in the camera action camera segment - you want to be the first to catch up with us. That is, zapadlo will telepath for the Chinese, and they will indulge in it, either release the camera on a new chip earlier than the scheduled time or release two cameras in a year ... or delay and delay the release of the new camera until the new year. The last option is the most unprofitable.
That is, Yi will make the main competitor suffer losses and get trumps from his hand earlier than he wishes.
That is, Yi is now making an estimate of the market they have mastered ... and by the release of "hero 6" already and the percentages will be cheaper, so yi can safely lower the price by $ 100 and continue to keep its sales at a good level. In short, the Chinese are smart and take risks.

Well, we what? Correctly, we will wait patiently for the release of the sale of hero6 and in November-December we will buy yi 4k + for 20t.r.- iron ... if not even cheaper (with coupons, yes cashbacks and other promotions)

And speed, and depth and height can fix (if only it was turned off, and then the battery as it is a pity, motorcycle racer, cyclists, parashutis and divers will appreciate of course, but I would be better and more interesting would be $ 70 cheaper)
