Before we show you the video, it's probably best to explain that, as the name suggests, Hybrid AF is a mix between two autofocus technologies, the traditional contrast-based autofocus, and a more modern Phase Detection autofocus tech. When combined, the two technologies allow a camera to quickly focus on the subject.
The video below, published by Taiwan's ePrice, shows that the Hybrid AF on the Sony Xperia M5 Aqua can focus on the subject much faster than the simple, contrast-based autofocus system available on the HTC One M9+. Take a look for yourself:
Although the Xperia M5 is interesting by itself, the reason why we take particular interest in the handset's 21.5MP camera is because there's reason to believe that upcoming Xperia Z smartphones - such as the Sony Xperia Z5 - will make use of the same sensor, probably paired with the same autofocus system. The 13MP secondary shooter on the front, a major attraction for selfie fans, will probably make its way to upcoming Sony high-end smartphones as well.
According to recent information, the mid-range Sony Xperia M5 will sell for about $400 unlocked. The handset comes with a 5-inch IPS LCD screen with a resolution of 1080 by 1920 pixels, a MediaTek Helio X10 MT6795 chipset (octa-core Cortex-A53 CPU clocked at 2.0GHz, PowerVR G6200 GPU), 3GB of RAM, 16GB of expandable internal storage, and a 2600mAh battery.
