• Advanced Video Capabilities: While retaining the core video specifications of the original a1, the a1 II introduces new features like Dynamic Active Mode Stabilizer, Framing Stabilizer, and Breathing Compensation, further enhancing its video recording capabilities.
• Refined Body Design: Inheriting the a9 III's body design, the a1 II offers improved ergonomics, weather-sealing, and compatibility with the latest accessories. The LCD and EVF have also been upgraded for a superior user experience.

Autofocus System Powered by AI

The a1 II leverages the power of its AI Processing Unit to deliver an autofocus system that sets a new standard in speed, accuracy, and intelligence.

• Expanded Subject Recognition: The camera can now detect and track a wider range of subjects, including humans, animals, birds, insects, cars, trains, and airplanes.
• Human Pose Estimation: This technology accurately tracks body and head positions, ensuring precise focus in portraiture and dynamic sports photography. Real-time Eye AF performance has also been improved by 30%.
• Real-time Tracking: AI-based subject recognition enables the camera to seamlessly follow moving subjects, making it ideal for capturing action and sports.
• Focus Area Customization: The addition of XS and XL focus area spot sizes provides greater flexibility for capturing subjects of varying sizes. Users can also customize AF focus areas to match unique subject shapes.

Professional Video Features

The a1 II builds upon the a1's video prowess with new features and refinements that cater to the needs of professional videographers.

• High-Quality Recording Formats: The camera supports familiar recording formats, including 8K 30p with 10-bit 4:2:0 sampling and 4K 120p with 10-bit 4:2:2 sampling. Oversampling options further enhance detail and clarity.
• Framing Stabilizer: AI subject recognition powers the Framing Stabilizer mode, automatically cropping and recomposing footage to keep the subject centered.
• Dynamic Active Mode Stabilization: This feature helps maintain stable footage while recording on the move, minimizing unwanted camera shake.
• Breathing Compensation: Support for Breathing Compensation mode reduces the distracting effects of focus breathing when using select lenses.

Enhanced Stills Capture

Beyond its video capabilities, the a1 II excels in stills capture, offering a range of features that cater to diverse photographic needs.

• High-Speed Continuous Shooting: The camera can capture images at up to 30 fps at full resolution, with a buffer capable of handling extended bursts.
