Sony has announced two "super mid-range" smartphones, the Xperia C5 Ultra and Xperia M5, due for release later this month - though neither will be available in the UK.
Both devices run Android 5.0 Lollipop and are targeted primarily at the consumer market, although the high-end specs could enhance their enterprise appeal.
The Sony Xperia C5 Ultra (above right) has a large 6in FHD display, 1.7GHz, 64-bit octa-core processor, 2GB of RAM, 16GB of internal storage, aluminium frame and a 2,930mAh battery which Sony claims will offer two days of life.
The headline features are the twin 13MP front and rear cameras, the former including a 22mm wide-angle lens.
The 5in Sony Xperia M5 has a slightly smaller battery at 2600mAh but a more powerful processor and rear camera than the Xperia C5 Ultra. The 64-bit octa-core chip is clocked at 2GHz, with 3GB of RAM, while the main camera includes a 21.5MP sensor and the ability to capture 4K video.
In addition, the Xperia M5 is certified to the IP65 and IP68 standards, meaning it is completely dust-tight and waterproof to depths of over 1m.
The two handsets will be available in single-SIM and dual-SIM variants. Dual-SIM devices are popular with business users for their ability to support a personal and work-specific SIM simultaneously, or for adding a separate pre-paid SIM when travelling abroad.
The Xperia M5 is a rapid follow-up to the Sony Xperia M4 Aqua, another waterproof smartphone released earlier this year with specs that would also put it in Sony's so-called "super mid-range" bracket.
This range seems to exist to offer more powerful hardware than ‘budget' Android phones can manage, without directly competing with the top-end Sony Xperia Z3+.
The Xperia C5 Ultra and Xperia M5 will be launched in "selected markets" from mid-August 2015. Prices and specific release dates for the UK have yet to be confirmed.
