Smartphone Xperia Z5 Premium is able to record video in “super resolution” and display it in the same resolution, the display diagonal of 14 cm.
On all smartphones Z5 installed new cameras. This part of the smartphone Z Series significantly updated since 2013, when the model was released Z1.
The division of the company Sony, which produces mobile phones at a loss, but the division that produces units for the cameras, brings the company’s income.
Apple, Samsung, Xiaomi and Huawei – are just some competitors Sony, used it earlier generations of technology. However, Sony said that its new 23-megapixel sensor will soon be used exclusively for its own devices the company.
The company predicts that its division, which produces mobile phones, the current fiscal year will end with a loss of $ 500 million . However, the production of sensors, including for larger cameras in the same period the company should bring revenue of $ 4.8 billion.
Sony expects its production of mobile phones will become profitable again in 2016. However, the head of the company said that if this unit will not be profitable, there is no guarantee that Sony will continue to manufacture smartphones within five years.
Battery
its new smartphone operating system Android Sony unveiled at IFA electronics show in Berlin.
The Company recognizes that the choice of professionally produced video in a format that is limited to 4K. However, according to company representatives, Z5 Premium will reformat the videos offered by YouTube and Netflix, in order to take advantage of the display.
One of the problems 4K is that it is much faster than the battery consumption in the handset. However, users, saving consumption of phone battery will be able to disable this option.
Sony stated that the use of the battery capacity of 3,430 mAh and new technology allows you to save a static picture is displayed without the power consumption will enable to extend the work to charge up to two days.
However, at least one expert expressed doubts. “I doubt very much that the battery will last for two days if you watch the video in 4K,” – said an employee of the research company in the field of high technologies IDC Francisco Jeronimo.
“From a user perspective there is no need to display 4K, – he said. – It is actually an attempt to offer the customer something that can not offer the competitors. This is a way to draw attention to the brand “.
” The fastest autofocus “
The new Sony video module is equipped with a stabilization system that responds to shake the phone and compensating its corresponding movement of the lens. As a result, the picture has a smaller tremor.
An additional element in the design of the camera allows more light strikes the sensor, which should lead to better shooting in low light.
Sony also increased the number of pixels on the sensor, allowing phase focusing. They are used to increase the speed of autofocus. Now, the pixels with a phase focusing cover the entire area of the frame, and not only its central part, as it was before.
As a result, when focusing on a subject at the edge of the frame, autofocus is faster and more confident.
The company says that these innovations will reduce the time to 0.03 seconds auto focus. This, according to the assurances of Sony, the fastest AF among smartphones.
Minimum difference
However, Francisco Jeronimo doubt that such innovations will impress users.
“The big question is – will appreciate whether users appreciated these qualities when they are photographed, – he said. – I took a few photos of the sixth iPhones and the new Sony Z5 Premium in low light, and frankly, the quality was the same” .
“When you reach a certain technical level, it is very difficult to see a difference if you do not print pictures of a large size. This applies to most high-end smartphones,” – says the expert.
Nevertheless, he says, there is a big chance that this sensor in the future emulated by other manufacturers of smartphones, if it would be better than the competition according to the results of independent tests.
One of these competitors is the new sensor S5K3P3 by Samsung , the resolution of which is somewhat smaller (16 megapixels), but it is significantly thinner and allows you to embed the camera even in the thinnest smart phone.
