If you've been eagerly waiting to experience photography with the Sony Xperia XZ2 Premium, your wait will soon be over. The phone is slated to ship at the end of July for $1,000 -- and if you buy from Amazon, it'll toss in the new, completely wireless Xperia Ear Duo headphones. 

The phone made a splash when it was announced because of its particular dual cameras: a monochrome and a color. That's how Huawei configures its dual cameras, designed to deliver better tonal range and low-light sensitivity rather than zoom, as most other dual camera setups do. Plus, the color camera uses Sony's IMX400 three-layer stacked BSI CMOS, which delivers the speed necessary for its higher resolution slow-motion capture.
