At $2,500, the Sony Xperia Pro is so much more than a phone The device has HDMI input that lets you use it as a field monitor for a standalone camera and even broadcast a live video signal to a platform like YouTube. Listen - 05:37 Here's the Sony Xperia Pro mounted on a Sony A7S III mirrorless camera. An HDMI cable allows you to use the Pro's 4K display as a field monitor. Patrick Holland/CNET Over the past few years, with phones like the Xperia 1 II (read as "one mark two") and the Xperia 5 II, Sony's moved away from mainstream appeal and aimed itself at photo and video enthusiasts. The new Sony Xperia Pro is the most extreme example of this move to date. The $2,500 phone (which converts roughly to £1,830 or AU$3,250) isn't meant to compete with the likes of the iPhone 12 Pro Max or the Galaxy S21 Ultra. Its HDMI input transforms it from a phone into several other devices for photographers, videographers and live broadcasters.
