Sony announces the Xperia Z2 with 4K video capture official on the MWC 2014 in Barcelona


Sony just announced the Xperia Z2 flagship, a refinement of last year's Xperia Z1.

It has a 5.2" screen - a 1080p Triluminos IPS screen, with the same Bravia tech used in Sony's TV.

The 20.7MP camera has been updated with 4K video recording (at 30fps) and a number of new effects. The camera features the same 1/2.3" sensor with 27mm G Lens with f/2.0 aperture.

One of the new effects is Timeshift, which records 720p video at 30fps. Another one is the Background defocus, yet another is a dedicated mode for Vines.

It's powered by Qualcomm's new Snapdragon 801 chipset with four Krait 400 cores at 2.3GHz and 3GB RAM.

Despite the size increase, the new flagship is only a little taller and actually narrower and thinner. The battery capacity went up a tad to 3,200mAh, while the weight went down to 158g.

As before, the Xperia Z2 has an IP58 certification, allowing it to work under water.
The phone will launch in March at €600 / £600. The initial color options are White, Black and Purple.
Sony will also pack an advanced headset with digital noise cancellation, the Sony MDR-NC31EM (normally £40).

Sony Xperia Z2 hands-on

The Xperia Z2 is Sony's first flagship device of 2014. We received a quick demo of the smartphone and we also spent time with it ourselves:
The Sony Xperia Z2 takes after the Z1 (which is to say it looks hot), but it has a larger screen – a 5.2" Triluminos display. The display has 1080p resolution, despite all the rumors of QHD screens at the MWC. The sharpness is great though and Sony has used the same tech for the screen as it does for its TVs.

5.2" Triluminos screen
The camera features a 20.7MP Exmor RS sensor and Sony has finally enabled 4K video recording @ 30fps (aka 2160p). You can use digital zoom during video recording, but we've yet to see if it's as good as the Note 3's.
Some new camera modes include 120fps slow-motion (at 720p resolution) and Background Defocus, and Vine is pre-installed.
The Xperia Z2 runs Android 4.4.2 KitKat with Sony's customizations, which have gotten a reputation of minimal but functional changes to Android. More interestingly, Sony uses Qualcomm's brand new Snapdragon 801 chipset – an improved version of the already fast 800.

The Xperia Z2 little narrower and thinner than the Z1
Sony's Z phones have never been the loudest round (the price to pay for water-proofing), but the Xperia Z2 features stereo speakers, so it might be better.
Sony continues to use its long process of carving a thin, light chassis out of a single slab of aluminum. The Xperia Z2 is 12g lighter than its predecessor. Here are the steps of the process:

Creating the Xperia Z2 body is a lengthy process
The larger screen led to a slight increase in size but that's only in the vertical dimension, the Xperia Z2 is 2.4mm taller than the Z1, but a hair narrower and thinner. As before, the body has IP58 certification, so it can go as deep as 1.5m under water for half an hour..
So can other Sony products, there was an impressive presentation on that too:


The Sony Xperia Z2 comes with 16GB of built-in storage and a microSD card slot. The slots and ports are covered by flaps to prevent water damage.
Speaking of ports, the microUSB 2.0 port features MHL and can output 4K video - now all you need is a 4K TV to watch the videos you've shot in their full glory.

Xperia Z2 camera samples

The Xperia Z2 camera follows the Z1 and Z1 Compact guidelines - 20.7MP Exmor RS sensor, 1/2.3" big, Sony G Lens (f/2.0, 27mm wide angle). We couldn't take the phone outside, but we still captured a sample photo:

And we recorded a 4K video too. Here it is uploaded to YouTube, but you can also download it to avoid the extra compression. Keep in mind that your computer and video player need to be able to handle 4K video. If not, at least you can view the YouTube video at 1080p.

Xperia Z2 benchmarks

We had just enough time with the Z2 to run several of our usual benchmarks - this is our first encounter with the Qualcomm Snapdragon 801, so we didn't know quite what to expect. The Xperia Z2 chipset is clocked at 2.3GHz and has 3GB of RAM, so it should do well against other flagships. It's worth pointing out the device is still a month away from store shelves.


Running benchmarks on the Xperia Z2
We will repeat the benchmarks once we get more time with the Xperia Z2, but the GPU performance is quite impressive. The processor didn't top the charts, but performance is still very good.
