Overview

The Sony Xperia PRO-I is purpose-built for creators who want professional-caliber imaging in a device that fits in a pocket. At its core is a 1-inch Exmor RS sensor—dramatically larger than what you'll find in competing smartphones—paired with a triple-lens camera system co-engineered with ZEISS. The three focal lengths (16mm ultra-wide, 24mm wide, and 50mm telephoto) cover the most commonly used perspectives in both photography and videography, while the 3D iToF sensor provides fast, precise depth mapping for reliable autofocus even in challenging conditions.

Where the Xperia PRO-I truly stands apart is in video. It is the first smartphone to offer native 4K recording at 120 frames per second, enabling buttery-smooth slow-motion footage without the resolution compromises other phones impose at high frame rates. Combined with 512GB of onboard storage and 5G connectivity, the device is designed for creators who shoot, edit, and share on the move. The unlocked 5G radio ensures broad carrier compatibility, while Sony's professional video apps provide manual controls for exposure, white balance, and audio levels that mirror the workflow of dedicated cinema cameras.
