Sonys Xperia Z5 Premium Phone: First 4K Display and Fastest Autofocus

Sony today unveiled its new Xperia Z5 family of smartphones, which breaks new ground in the camera and display department thanks to the line’s high-end Xperia Z5 Premium phone. That phone features a 23MP sensor, an f/2 lens, the world’s first 4K display on a phone, and the world’s fastest autofocus in its camera module

While Xperia Z5 and Z5 Compact smartphones were also announced, it’s the Z5 Premium that steals the show. Sony is bringing its camera world prowess to the phone world, adding technologies from its interchangeable lens cameras to its Xperia smartphones. 

Inside the camera is a large 1/2.3-inch Sony Exmor RSTM sensor that shoots 23-megapixel photos through an f/2.0 G 5x zoom lens. It’s the first time Sony has completely revamped its smartphone camera module since the Xperia Z1. 

The camera has the fastest AF system of any smartphone, focusing on subjects in just 0.037 seconds — “faster than the blink of a human eye,” Sony boasts. 

On the front of the camera is a massive 5.5-inch 4K display that’ll give you eye-popping detail when framing or reviewing your shots. It’s the first time a 4K display (3840x2160px) is appearing on a phone.
