The Xperia Pro-I is a new Xperia Pro phone from Sony. Outside of Japan, the Xperia Pro-I is the first phone to include a 1.0-inch camera sensor with phase-detect focusing.
The I in Xperia Pro-"I" stands for imaging, a nod to Sony's popular Alpha mirrorless interchangeable lens cameras and professional video cameras.
The new Sony smartphone uses the same 1.0-type Exmor RS image sensor with phase-detection AF that powers the RX100 VII, vloggers' and tourists' favourite point-and-shooter.
The Xperia Pro-I uses a major portion of that sensor to create 12MP photos with a 2.4m pixel pitch, which is around 20% bigger than the iPhone 13 Pro Max's pixels and about the same size as the Galaxy S21 Ultra's primary camera's pixels after binning.
A Zeiss-coated stabilised 24mm lens sits in front of the Exmor RS sensor, with a variable aperture that ranges from f/2.0 for the shallowest depth of focus to f/4.0 for the sharpest image.
The BIONZ X image processor used in Sony's A9 professional mirrorless camera for sports is included in the Xperia Pro-I, allowing it to snap burst photos at up to 20 frames per second.
Another set of 12MP cameras are found on the Xperia Pro-I: a 16mm f/2.2 ultrawide lens and a 50mm f/2.4 2x telephoto lens.
Sony has included two physical camera controls on the Xperia Pro-I. A two-stage shutter key and a circular shortcut button that has the Videography Pro app assigned to it.
The Xperia Pro-I will ship in December 2021 for a whopping $1,800 (~ 1.35 Lakhs).
