After leaking last week, Sony has made the Xperia M5 official. This device is the spiritual successor to the Xperia M4 Aqua, but it has a more impressive camera. The 21.5MP sensor is joined by Sony's customary waterproof design and a 5-inch 1080p display.
Sony is calling this a "super mid-range" phone, which I guess can be a thing if Sony really wants. At any rate, here are the relevant specs so you can see what super mid-range gets you.
The camera will reportedly use a hybrid autofocus system to bring focusing time down to a mere quarter of a second. It also has a f/2.2 lens and can do up to ISO 3200. The somewhat modest hardware will allow that 2600mAh battery to keep ticking for (allegedly) two full days.
