Sony’s Xperia XZ2 Premium has a 4K display and cameras built for ‘extreme’ low-light

Less than two months after unveiling the Xperia XZ2 at Mobile World Congress, Sony is back again with the Xperia XZ2 Premium. It retains the same overall design as the XZ2 — a departure from Sony’s past phones — but upgrades the display, camera, battery, and other specs. The XZ2 Premium will be available beginning this summer. Pricing has yet to be announced, but it certainly won’t be cheap. The XZ2 runs $800 unlocked, so you’re probably looking at a $900 or $1,000 phone here.Sony is putting a 5.8-inch 4K display in the XZ2 Premium, an improvement over the 5.7-inch Full HD+ (1080 x 2160) screen on the regular XZ2. Both of them support HDR video. When you’re watching videos, listening to music, or playing games, you’ll notice the new vibration system that debuted in the XZ2; it’s meant to provide rumble feedback to match whatever’s happening on screen, but felt somewhat gimmicky in my hands-on time with the standard model.The biggest upgrade here, according to Sony, is the camera. The XZ2 Premium has two of them around back a first for the company. Rather than adding a telephoto / zoom lens like Apple, Samsung, and OnePlus, Sony is splitting image capture between one 19-megapixel color sensor and a 12-megapixel monochrome.It’s an approach several other Android makers including Huawei have taken. Where Sony is trying to best everyone and stand out is in ISO performance. When shooting stills, the XZ2 Premium can reach a maximum ISO of 51,200. Videos go as high as 12,800. Normally anything you’d get at those numbers on a smartphone would look like grainy garbage, but Sony claims its “AUBE fusion image signal processor” can combine the data from both sensors, optimize for low light, and reduce noise so you get usable results. We’ll have to see how it actually pans out in real world use, but Sony claims this allows for “ultra-low-light capture previously only seen in interchangeable lens cameras.”
