Sony's new camera-focused flagship device, which has also been referred to as the Sony Xperia i1, will be officially revealed at the company's IFA press conference from 3:45pm today. However, we already know much about what the handset will offer.
The eager types over at Xperiablog have managed to get their hands on the official press release that will be distributed for the Sony Xperia Z1 announcement. A screen grab of this has since been removed at Sony's request, but the details remain.
In truth, much of it simply confirms what was already known - or at least strongly suspected - based on the numerous leaks that have preceded the Z1. It hasn't exactly been kept securely under wraps.
Still, we now know for sure that the Sony Xperia Z1 will feature a 5-inch 1080p Triluminos display. This will be housed in a "solid one-piece aluminium frame" with dimensions of 144 x 74 x 8.5mm, and it'll weigh a chunky 170 grams.
One interesting new point to note from the press release is that the Sony Xperia Z1 will be even more protected against the elements than the Sony Xperia Z, with a superior rating of IP55/IP58.
Internally, you can expect a 2.2GHz quad-core Qualcomm Snapdragon 800 CPU with Adreno 330 graphics, all backed by 2GB of RAM. On the storage front there'll be 16GB internal as well as a microSD slot, and the whole device will be powered by a 3000mAh battery.
Naturally, the Sony Xperia Z1 boasts of having the "world's leading camera in a smartphone," and even claims that "independent testing has confirmed that Xperia Z1 provides the best overall image quality of all leading smartphones."
This will come from a 1/2.3-inch 20.7-megapixel Exmor RS image sensor and a Sony G lens. The latter features a 27mm wide angle and an f/2.0 aperture.
Sony also talks of a suite of camera apps that will come pre-installed on the Z1, including Info-eye, AR effect, Timeshift burst and Social live. It also sounds like you'll be able to auto-upload all of your photos to Sony's PlayMemories Online service with no storage limitations.
Customers in the UK, Japan, US, France and Germany will be able to search and share TV info with a new app called TrackID TV.
All of this will operate under Android 4.2.2 to start with, so it's still not quite the very latest version of Google's mobile OS.
We'll have this confirmed in just a few hours, but we're not expecting any great surprises from Sony's IFA smartphone showing - at least not from the Sony Xperia Z1, code name Honami.
