Sony is said to be working on a successor to its Xpera Pro-I smartphone from last year. According to that rumor, there will be three large camera sensors in the phone, all three with a resolution of 48 megapixels. The primary camera would have a variable aperture.
The Chinese source mentions the three camera sensors: it would be the Sony IMX903, IMX803 and IMX557. Of those type numbers, only the IMX557 is known as a camera in recent other Xperia phones, in which it has a resolution of 12 megapixels. How that could suddenly become a 48-megapixel sensor is unknown.
The rumor is in line with how Sony feels about phone camera setups. In recent phones, all three cameras have the same resolution, although the size of the sensors is different. A variable aperture is not new either. It’s actually already using it on the Xperia I IV’s telephoto camera, which has a variable zoom telephoto camera. It seems that in the successor to the Pro-I, the primary camera has a lens opening that can open and close. The aperture switches between f/1.2 and f/4. There are no smartphones with an aperture of f/1.2 yet.
The primary camera, like the Pro-I, has an area of around 123 square millimeters with an optical size of 1″. The camera with ultra-wide angle lens comes to 69 square millimeters, 1/1.3″. The telephoto camera is rumored to have a sensor of around 40 square millimeters, 1/1.7″.
The Pro-I came out last year for 1799 euros and is considered the most luxurious smartphone from the manufacturer, aimed at photo and video makers. For example, the phone can be used as an external monitor for cameras via a USB-C to HDMI adapter that Sony provides.
