- Up to 30 fps continuous shooting with an electronic shutter, or 10 fps with the mechanical shutter, with AF and AE supported.
- Pre-Capture Shooting records at up to 30 fps for up to 1 second prior to fully pressing the shutter, helping to ensure you don't miss fleeting moments.
- Speed Boost lets you vary your continuous shooting speed mid-burst; when the C5 button is depressed while burst shooting, you can switch from the chosen continuous shooting speed to a faster or slower one to suit the pace of action you're photographing.
- Refined 5-axis in-body image stabilization compensates for up to 8.5 stops of camera shake at the center of the frame and 7 stops at the periphery; an improvement of 3 stops of shake control compared to the original a1.
- Same full-frame 50MP stacked BSI CMOS sensor as the a1, mixing high resolution with the speed and reduced rolling shutter of a stacked design to suit both meticulous and quick-working shooters.
- First seen in the a7R V and a9 III, the a1 II sports a dedicated AI Processing Unit for refined, responsive, and intelligent subject tracking and detection of humans, animals, birds, insects, cars, trains, and airplanes.
- Human pose estimation tracks body and head positions for accurate focus in portraiture and sports settings and Real-time Eye AF performance has been improved by 30%.
- Additionally, human pose estimation can distinguish between multiple people and maintain focus on the targeted subject; even if someone crosses in front, the camera maintains focus on the key person.
- Real-time Tracking benefits from AI-based subject recognition for following moving subjects, making it particularly well-suited to sports and action subjects.
- Auto Subject Recognition modes no longer necessitate selecting a subject type, letting the camera detect and track the intended subject.
- XS and XL focus area spot sizes have been added for more versatility or you can customize AF focus areas to suit uniquely sized or shaped subjects.
- Full-time DMF (Direct Manual Focus) enables using the lens's focus ring for manual focus control at any time, making it easier to switch focus to a different subject even when working with AF.
- Familiar recording formats: 8K 30p with 10-bit 4:2:0 sampling and 4K 120p with 10-bit 4:2:2 sampling. When using a Super 35 recording area, 4K footage can use 5.8K oversampling for improved detail and the full-frame area offers 8.6K oversampling for the 8K footage.
- AI subject recognition, gained from the AI Processing Unit, benefits the Framing Stabilizer mode, which can be used to automatically crop and recompose so the subject remains centered in the image.
- Dynamic Active Mode Stabilization also helps retain accurate framing while filming, especially when recording while walking or moving.
- Included S-Cinetone profile, ProRes RAW output over HDMI, and the ability to import LUTs all point to the great amount of color control the a1 II offers.
- Support for Breathing Compensation mode, which reduces the effects of focus breathing when using select lenses.
- Pre-Capture: The a1 II can be configured to begin recording images to the buffer when the shutter button is half-pressed. Users can set this between 0.03-1.0 second. Upon pressing the shutter these images will be saved to the memory card.
- Speed Boost: With Speed Boost and the C5 button, which is conveniently placed near the grip on the front of the camera, users can instantly switch their camera from their usual continuous shooting frame rate to a faster one to make sure their next shot is just right. Photographers will be able to select various frame rates up to 30 fps.
- The a1 II gains the latest Sony mirrorless body design first seen on the a9 III which includes a C5 custom button on the front of camera body and an enhanced grip.
- For transferring, an upgraded 2.5GBASE-T wired LAN port offers faster transfer speeds to suit high-profile tethered shooting applications. There is also a USB-C port and a full-size HDMI port.
- USB-C port offers fast USB 3.2 Gen 2 speeds of up to 10 Gb/s.
- Dual memory card slots both accept either CFexpress Type A or SD-type memory cards. The dual slot design allows for flexible file saving and handling and can be configured to partition file types or can be used for overflow recording. Additionally, both of the card slots are rated to support UHS-II memory cards for faster transfer speeds.
- An impressive QXGA OLED Tru-Finder EVF features a high 9.44m-dot resolution and 0.9x magnification for exceptionally bright, clear, and detailed eye-level viewing. There is also a 120-fps option that maintains the higher resolution for a better mixture of clarity and motion fluidity.
- 3.2" 2.1m-dot 4-axis multi-angle touchscreen LCD-first seen on the a7R V. This screen has a wide color gamut covering the DCI-P3 space.
- Intuitive menu structure that complements having different workflows with different settings selections for movie recording and stills shooting. The menu system also works in conjunction with the touchscreen design of the rear LCD.
- A voice memo function promises clearer recording with a microphone located close to the user. These memos can be transferred via FTP and can be converted to text using Sony's Transfer & Tagging application.
- IPTC metadata can be automatically added to images and up to 20 presets can be saved.
- Built-in Wi-Fi and Ethernet can be used for fast networked data transfer during shooting.
- Pixel Shift Multi Shooting: This unique compositing mode allows you to achieve even greater resolution than the 50.1MP sensor affords. Working in conjunction with the sensor-shift image stabilization, this mode shifts the sensor while making 16 consecutive exposures in order to acquire approximately 199MP of information for greater color accuracy and detail than possible with a single exposure. These files can then be merged together during post-production by using the Sony Imaging software suite.
- Noise Reduction: This method uses multiple images to reduce the noise in an image without sacrificing sharpness and detail. By leveraging the information of several frames, users will be able to improve the legibility of details and minimize the impact of noise without the smoothing effect common with more conventional noise reduction techniques.
- Fast f/1.4 maximum aperture benefits working in difficult lighting conditions and offers a wealth of control over focus position when using shallow depth of field techniques.
- A Nano AR II Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions.
- Rounded 11-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
