WHILE WE WERE EXPECTING JUST THE ONE Xperia Z5, Sony announced three models versions of the smartphone during its IFA press conference: the Xperia Z5, Xperia Z5 Premium and the Xperia Z5 Compact.
With the trio of handsets bound for UK shores, we've rounded up everything you need to know about buying one below. We'll update this page when we hear more, so be sure to keep it bookmarked.
The Xperia Z5 and Xperia Z5 both saw an October launch, while the Xperia Z5 Premium will arrive on shelves the following month on 20 November.
Sony was quick to reveal pricing details for its trio of Xperia Z5 handsets over on its website. The Xperia Z5 Compact is, unsurprisingly, the cheapest of the three at £429, followed by the Xperia Z5 at £549. The Xperia Z5 Premium, which is available to pre-order, is the most expensive of the three at £629 SIM free.
For those looking to pick up an Xperia Z5 smartphone on contract, there's plenty of choice.
EE has the Xperia Z5 in stock. It can be picked up over at the EE website from £49.99 on a £41.99 tariff, complete with 1,000 minutes, unlimited texts and 1GB Data. It also has supply of the smaller Xperia Z5 Compact, which can be picked up for £49.99 on a cheaper £36.99 per month contract.
O2 is selling the Xperia Z5 in black and green, and it can be picked up for free from £42.50 per month, with 1GB data included. It's also selling the Xperia Z5 Compact in black and yellow flavours, with prices starting from £37.50 per month, including a free handset, unlimited texts and minutes and 1GB monthly data.
Three will offer the Xperia Z5 in black, and has started taking orders. It can be picked up with a choice of 1GB, 2GB or unlimited data for £39, £48 and £54 per month, respectively, and will start shipping on 12 October. The operator is also offering the pint-sized Z5 Compact for £29 on a choice of £21 and £24 per month tariffs.
Vodafone is offering the Xperia Z5 in black and green models over on its website. Pricing for the phone starts at £9 on a £44 monthly tariff, which comes with 2GB monthly data. The Xperia Z5 Compact is also on offer at the Vodafone website, costing £9 on a £35 tariff.
Carphone Warehouse, which has bagged itself an exclusive on the white Xperia Z5 Compact and the 'ice white' Xperia Z5 models, was the first to start taking orders. Over on its website the Xperia Z5 Compact is available to order from £30 per month with a £59.99 upfront cost, or £449.99 SIM-free. The Xperia Z5 can be picked up from £40 per month with a £29.99 upfront cost, or for £549.99 SIM free.
The retailer is also the first to offer the top-end Xperia Z5 Premium for pre-order, with shipping promised for 20 November. Prices for the handset start at £49 per month, complete with unlimited minutes and texts and 2GB monthly data.
The Xperia Z5 is the successor to Sony's Xperia Z3+, and offers the IP65/IP68 dust-tight, waterproof design with cap-less USB port, and measures in at 7.3mm and weighing 154g. However, #mce_temp_url#Sony has admitted that it's in fact not that waterproof and has advised that users keep it away from water.
It boasts a 5.2in full HD display, Android 5.0 Lollipop (with an update to Android 6.0 Marshmallow on its way), 3GB RAM and Qualcomm's notorious Snapdragon 810 processor. This is the chip that featured in the Z3+ and was blamed for its overheating problems, which resulted in an unexpectedly low score in our review.
The Xperia Z5 also brings Sony's next-generation camera sensor, the larger 1/2.3 Exmor RSTM for mobile with 23MP sensor and F2.0 G Lens. The snapper also boasts the 'world's fastest' autofocus at 0.3 seconds, Clear Image Zoom and improved low-light performance.
Another new features in the Sony Xperia Z5 is the addition of a fingerprint sensor on the side. Sony has somehow managed to return the same small size of the power button but added fingerprint technology on top of this so you can unlock the device when you pick it up, without having to then move your hand to a separate button to unlock the screen.
Apart from a slightly different design and bigger and thicker form factor, the Xperia Z5 Premium has all the same features of the Xperia Z5 but is what Sony calls "the world's first 4K smartphone" with a slightly larger 5.5in 4K display made with the firm's Triluminos TV screen tech.
The Xperia Z5 Premium measures in at a chunkier 7.8mm, and tipping the scales at 180g, and packs a bigger 3,430mAh battery than its non-Premium sibling. This is to support the power-hungry 4K screen to power the smartphone for two full days, Sony said.
Other differentiators include Xperia Z5 Premium features such as a larger 32GB internal memory, with the capability to take a 200GB external microSD card, which offers extra room for 4K videos and images.
The Xperia Z5 Compact offers same features as the Xperia Z5, such as the same updated camera sensor and Snapdragon 810 chip, but is actually the thickest of the bunch despite its name at 8.9mm.
Still, the Compact model has a generally smaller form factor owing to a 4.6in 720p HD screen with 1280x720 pixels resolution, as well as a smaller 2700mAh battery and slightly lower RAM offering of 2GB. µ
