The massive volume of data from the 50.1 megapixel*1 full-frame Exmor RS image sensor is processed in real time by Sony’s BIONZ XR image processing engine. An advanced AI processing unit applies high-level subject recognition to reliably recognize a wide range of subjects.
The α1 II features a dedicated AI processing unit that helps to recognize people more accurately based on human pose estimation and supports recognition of a wide range of subjects other than people, such as animals, vehicles.
Real-time Recognition AF has improved human eye recognition by approximately 30%*6, and its human pose estimation technology also delivers precise recognition of subjects facing away from the camera, wearing sunglasses, or with the face obscured.
A wider variety of subjects*7 is now recognized for stills and movies, with a new [Auto] mode letting the camera select. *8 Recognition of animals overall is improved by approximately 30%*6, with eyes of some small animals added, and the eyes, heads and faces of animals like dogs and cats recognized.
Fast Hybrid AF combines phase detection and contrast detection for superb speed, precision and tracking performance. 759*10 phase-detection points cover 92% of the image sensor.
XL and XS focus area spot sizes are now available in addition to the existing L, M, and S. XS can be useful to avoid focusing on foreground objects such as branches. It is also possible to create a custom focus area of specified size and aspect ratio, useful in situations like a track event where athletes are lined up side-by-side and you want to focus on the leading runner.
Selectable release time lag modes are available via the [Release Lag] / [Start Display] menu *16.
High-speed continuous shooting at up to 30 fps*2 with full AF/AE tracking is possible at a stunning 50.1 MP*1 resolution, with up to 120 AF/AE calculations per second*12 on the data from the image sensor.
