Sony produces excellent "buttercake" with interesting Park of optics, delivers a chic camera sensor of smartphones various manufacturers. And boring situation with cameras in her own smartphones puzzling — "shoemaker without shoes"? But now Sony has released the Xperia XZ Premium combines the achievements of a series of Alpha cameras and Cyber-shot, have optimized their hardware and added features in smartphones until now did not exist. What a unique camera of the new device, and why for testing it had to burst balloons with water, read the review.
The new Premium flagship Xperia XZ has a unique 19-megapixel sensor — a modified Exmor RS IMX300. The physical size of the sensor — 1/2,3", the pixel size on it — 1.22 microns (about the value of these parameters can be read here).
The PV panel uses the algorithm of processing of images of BIONZ for mobile. This technology has migrated to the smartphone from the professional cameras of Sony, which for its operation uses a separate processor. BIONZ for mobile the Xperia XZ Premium is responsible for expedited processing of camera images and detect movement in the frame.
As you know, the camera does not only depend on the characteristics of the sensor and software algorithms for image processing, but also on the type of the attached lens. The Xperia XZ Premium main camera is equipped with a six-element (6P) G lens with a focal length of 4 mm — viewing angle that corresponds to 25 mm in 35-mm film equivalent. On the one hand, such a lens wide enough to capture a space frame a lot of objects, and, at the same time, not so "wide angle" to annoy geometric distortions. One word — the Golden mean. The minimum possible focusing distance with macro photography, this lens is 12 cm, aperture — F2. 0.
As befits a flagship device in the Xperia XZ has a Premium additional hardware for correct operation of the main camera. On the rear panel next to the flash mounted laser autofocus sensor and IR-RGB. System laser pickup allows you to quickly focus at a relatively close-up subjects, and when shooting distant from the camera object using the phase tracking autofocus. Sensor IR-RGB in turn runs "in advance" so that the white balance was set correctly even in conditions of mixing of light from lamps with different color temperature. As a result, shots always have great color reproduction and without requiring a user to adjust the white balance (although there is such a possibility).
Other hardware features of note also the presence of a special bolt mechanism is able to maintain the sharpness of the shot in fast moving objects, and additional mechanical button on the right side of the device. Long holding this button activates the camera even when the screen is locked, short press performs the shutter release. Along with a special button for focus, zoom and shutter release you can also use the volume rocker — it all depends on the preferences settings.
The device has two basic modes of photograph: "superior auto" and manual.
The first allows you to get a smartphone out of a pocket and create the perfect shot by pressing one button — everything else is done by electronics. As it happens, and why the prefix "super" in the title?
And here the most interesting. Auto mode in the Xperia XZ Premium is not just the selection of shutter speed, ISO, servo focus and auto metering, and more. On the spur of the smartphone determines the type of scene (and very successfully) and produces a variety of adjustments to improve the result. That "thinking" smartphone on your subject you can learn from the tooltip — it may receive a message about the virtual effect of a fill light when shooting against the light, the macro mode, or activate a preset for landscape. What if this settings change every time it is hard to say, and many will probably remain a mystery "recipe" Sony. That could see: during backlighting automatically wyswietlacze shadows, contrasting scenes of running an analogue of HDR mode, macro shooting is enhanced by the saturation of certain colors, and in low-light conditions included a shift of the exposure to lighten the scene.
It is widely believed that auto mode is for beginners and it is impossible to achieve really good results, but here the situation is different. The fact that it is "on automatic" camera reveals many hidden features and benefits, not all of which are available on the "handbrake". For example, for shooting in total darkness it is better to use auto mode, so as soon as it supports extremely high ISO 12800, while in manual mode the maximum available ISO 3200. On the other hand, if you have a tripod and the focus is on results, not convenience, you can rather use manual mode and taking pictures at night with a tripod at a minimum of ISO 50 they, in turn, is available only in manual mode. In short, the best strategy is shooting with the Xperia XZ Premium — competent maneuvering between automatic and manual modes, with full understanding of the pros and cons of each.
When switching to manual shooting, you receive the ability to adjust the shutter speed from 1/4000 to 1 second, change the white balance in the presets, enter the exposure compensation from -2 EV to +3 EV (the minimum step is 0.3 EV), as well as to smoothly adjust the focus with the slider.
For all major modes, including photos and videos available patisia digital stabilizace (EIS) SteadyShot, and easy adjustment of brightness and color temperature.
Direct testing of the apparatus showed that in daylight smartphone can produce great results. Especially note the high quality of the optics in the corners is not "soap", chromatic aberrations are absent.
The night starts out pretty aggressive noise reduction to work, so at 100% zoom you can see how "eating" fine details. At the same time, in General, the photos are very nice in color, and the smartphone "sees" bright colors even in the pitch dark and sometimes "embellish" the image.
Capturing text from a device no problem.
Flash has several modes of operation: fill, anti-red-eye, torch and automatic. The brightness is average.
Shooting without flash flash photo
Panoramas are stitched together without artifacts and in high resolution.
Of auto combo from the branded treatments, and improvements in image is an analogue of HDR. Therefore, the conventional HDR mode in the form in which we are accustomed to perceive in the menu "machine" is missing, but appears when you switch to manual mode. It works quite well. Here is an example of images in manual mode with HDR and without:
HDR mode enabled the HDR Mode off (ISO50, shutter speed 1/640)
Shooting video
Device interesting the three main modes of video recording: 4K 30fps, Full HD 60 fps and verzamelen the shooting at 960 fps. The interface is a little weird ordered videography: some modes are in the video tab, and video recording in 4K I could sit in a section with additional applications.
Let's start with the first mode. Recording in 4K is produced in stereo and with a bitrate 54 Kbps. This mode provides the highest possible video quality. Files will be enormous sizes, and the detail on the freeze-frames will impress even the most demanding users.
Shooting at 60 fps is best for action scenes, when not the maximum clarity, and the quality and smooth display of fast moving objects.
Oh, and finally, the main "trick" — the ability to slow down any debatecountry period of time with 960 fps.
In this mode, the camera operates at the limit — as reduced to standard HD, the sound at the time of deceleration is disabled, and instead these "victims" have the opportunity to see usually invisible to the human eye, the grace of movements. Note that this is not a software effect, but a real movie from the "honest" 960 frames per second, which generates a finished video file.
So running "slower" in the daylight.
And burst the water filled balloons (shot at home by the light of a household lamp):
Most interesting is that for slow motion (and any other) no need to learn to seize the moment. Thanks to technology and the Predictive Motion Eye camera Capture always works proactively and anticipates movements in the field of view of the lens. Thus, even if the shutter button was accidentally pressed with a delay of 1 or 2 seconds, and the videos and series of photos will always be stored prior to formal shutter moments. It is very convenient as it allows you to easily remove of people jumping, pictures of stunt bikers, and just to catch fleeting moments, not even having the skills of a professional photographer.
Front camera
Front facing camera designed for selfies and videos with 13-megapixel module with wide-angle lenses, equivalent in angle of 22 mm at a full frame camera. Aperture at "glass" for selfie — F2,0, sensor — 1/3,06" Exmor RS.
During operation, the front camera can use a filter that smoothes the skin in the picture, the function of smile shutter and self-timer option from the display of the palm in the frame.
Premium Xperia XZ has an augmented reality mode, allowing, for example, the virtual to grow mushrooms on a glade in front of the house and settle her fabulous characters.
In AR mode also has many other great effects and a storehouse of virtual masks for the face.
There are in-camera, of course, different color filters and special effects, although these days you will surprise few people.

The scientists said that thanks to the giraffes managed to fly into space. The spacesuits, which are used for flight, were invented by analogy with the circulatory system of giraffes.
According to the researchers, the skin on the feet of animals is quite dense, which helps to create a sufficient pressure to the blood vessels of giraffes has not been extended. As scholars have noted, the internal pressure of the blood neutralizes external, by which blood is forced back up and helps the normal functioning of the heart.
During the creation of the space suits used the same system. Under the space suit the astronauts wear pants made of spandex and it helps them not to lose consciousness when strong overloads. Spandex squeezes veins, causing the blood rushes to the lower legs and the blood supply remains the same.

If the engineers from Cupertino and will not be able to integrate the fingerprint sensor in future iPhone, and the option of placing the module on the rear panel of the smartphone will not receive the approval of jony Ive, it can fit in the power button.
It follows from the materials of a new patent published by the patent and trademark office.
New patent issued to Apple engineers, offers a quite distinct and even convenient solution to house a fingerprint scanner.
This option, subject to its approval by the designers, it may be probably the most advantageous both from the point of view of labor for its production, and client repair costs in case of a failure.
In addition, in this case, designers do not have to turn the device into a colander, making an additional space for the scanner, and forcing the user to do the stretching fingers every time the need to access the contents of the smartphone.
On which of the abundance of accommodation options fingerprint sensor will be elected in Cupertino, only to learn in September. Taken from appleinsider.ru
