If you can’t compete with others in terms of price, do something unique“. Sony’s smartphone division does not shine, and there has been repeated talk of its closure. However, things changed when the entire r & d department was handed over to the person who also manages the development of the mirrorless and the professional video part: the numbers don’t matter, the important thing is to make sure that those who shoot with a Sony Alpha can have in his pocket a phone capable of providing, albeit with the due proportions, the same performance.

The new Xperia 1 IV was created for content creators, but also winks at gamers: it wants to be the phone that contains the DNA of all Sony divisions, the photographic, the PlayStation, the Walkman and the Bravia, for the part ” display.

A phone that it has some features that no one has ever brought to the market, first of all the optical zoom.

If we exclude some cameras of the past with protruding lenses, and if we remove some prototypes, the 85-125 that Sony has included in its new flagship is something new.

Sony had already given us a taste with the previous model, a phone with a double fixed focal length that used a single lens to manage telephoto and medium telephoto.

Now comes a further evolution: the 85-125 periscope has a mobile element that allows you to switch from one focal length to another, managing all the intermediate steps with the lenses only. As with true zooms, the aperture also changes: F2.3 at 85mm and F2.8 at 125mm, therefore a zoom that is also decidedly bright if we compare it to that of other manufacturers with periscope, which have much more closed lenses. The sensor is 12 megapixel and 1 / 3.5 “, the smallest sensor of the trio of cameras.

The other two sensors are also 12 megapixel: for the super wide one there is a 1 / 2.5 “Exmor RS equivalent to a 16 mm with F2.2 aperture while for the main one there is an even larger sensor, a 1 / 1.7 ”stabilized with F1.7 aperture and 24 mm focal length.

They are not standard sensors: Sony has in fact created sensors with a greater amount of DRAM on board to allow a much faster reading of the data, and both sensors are able to withstand a capture at 120 fps: this means that with each lens it is possible to capture video at 4K and 120 fps and take advantage of the features that were also present on past models but only on the main lens, such as Real-time Eye AF and Real-time Tracking to follow the subject. To help with low light there is, as on Sony cameras, the iToF 3D sensor while to reduce flare and refractions, the lenses have been treated by Zeiss with a special coating.

The Exmor RS for Mobile technology also lands on the front camera, 12 megapixel too and she too capable of shooting videos in 4K HDR. The fast reading of the data on the front camera allows you to enable multi-frame capture for noise reduction by subtracting and adding frames.

The fast sensor is a real game changer, especially for video: in addition to the ability to record 4K video at 120 fps for all cameras with the addition of stabilization, the phone can also use “multiframing” techniques on the video: record more frames of those he needs to increase the dynamic range.

Sony also manages to exploit the Snapdragon’s ISP processor better than others: it promises a continuous and uninterrupted zoom from super wide to tele, with a part that will be managed digitally and a part that will be totally optical thanks to the variable tele.

Being a “mark IV” model, it also inherits features from the previous model, such as bursts at 20 fps with fire and exposure management for each shot, the ability to use the phone as a screen for Sony Alphas and Livestreaming mode, that allows you to use the phone for shooting by combining it with the Vlog Monitor accessory, a support with monitor that allows you to record V-Log with 4G and 5G streaming, however, using the rear cameras instead of the front.

This alone would be enough to make the Sony Xperia 1 IV an excellent smartphone, however this is “only” the contribution made by Alpha and Cinealta. Inside the new Sony smartphone there is also a lot of Playstation: in addition to the 120 Hz display A dedicated gamma curve is also available that brings out the details in the low lights, helping FPS players find enemies in shadowy areas, an audio equalizer designed for gaming and a dissipation system to placate the hot Snapdragon.

For those who play there is also an interesting function, RT Record: in practice, it “pre-records” everything that happens on the screen and by pressing a button the session or the game action is recorded starting from 30 seconds before the pressure. Players can also send the game session live-streaming and those who do so can also view the comments coming from the various platforms while playing, allowing them to replicate and communicate with the public in real time.

The Sony Xperia 1 IV can also be used for live streaming via PC: it has an integrated audio mixer system that uses a single cable to send game audio, player audio and chat audio channel to the computer, included that of other players in chat.

Sony is also developing a gaming accessory that will be launched in the fall, capable of transforming Xperia into a sort of portable console.

After Playstation we move on to “Walkman”: double stereo speaker, with the possibility of reproducing 3D sound through Sony’s proprietary 360 Reality Audio (360RA) technology.

A hardware decoder has been implemented for decoding the 360 ​​Reality Audio signal, which obviously only works with those streaming services enabled for this format, such as Tidal for example. For those who want to listen to normal stereo tracks in 360, Sony has provided an upmix system, which converts the stereo track into a multichannel track.

The most important news from the audio point of view is not so much the 360 ​​audio, nor the fact that Sony has also kept the audio jack, but official support for Bluetooth LE, the new bluetooth format for audio streaming which will replace the SBS codec. Sony is ready, although a software update that will come later will be needed to enable it.

Still in relation to audio, and with a view to being a phone for content creators, Sony has included a new function called “Music Pro” inside the phone: it is a professional-level audio recorder that relies on a cloud backend. for remastering. According to Sony, the quality is identical to that of a professional firm, and for this very reason the service has a cost: registration is free, remastering in the cloud is subject to a monthly fee.

Let’s finish with Bravia: Sony keeps the 6.5 ”OLED 4K HDR screen in 21: 9 format and the new panel according to the company is 50% brighter. There is Dolby Vision, Dolby Atmos for movies and there is also the brand new BRAVIA CORE for Xperia service, derived from that offered for TVs: hundreds of content in 4K to be enjoyed in streaming at the highest quality.

The “phone” part is the more traditional one: IP68 certified body, Snapdragon 8 Gen 1, 12 GB of RAM and 256 GB of storage, 5000 mAh battery with fast charging and wireless charging. There is also an eye for the environment: zero plastic in the packaging, no charger in the package and no cables: there is only the phone, with a package that is 50% smaller than that of the previous model. It is difficult to make a reasoning related to the savings in not putting the charger: Sony does not sell millions of smartphones, his is a purely eco choice.

A jewel, and something different, with a price in line with that of other Sony products: to get your hands on Xperia 1 Mark IV you need 1,399 euros. It’s not cheap, but it’s a unique phone.
