Real-time Eye AF for birds 8
High-level subject recognition technology now makes it possible for Sony's Real-time Eye AF function to track and accurately focus on bird eyes, even if the bird suddenly takes flight or the framing changes. This innovative function easily meets the many challenges of bird photography. 1
Improved Real-time Eye AF for animals 8
Real-time Eye AF
Primarily designed for cats and dogs, this feature employs advanced subject recognition technology to reliably track and focus on animal eyes. 1 It even works if the animal's face is upside-down.
Combining state-of-the-art AI technology and evolved Fast Hybrid AF algorithms, Real-time Eye AF in the α1 tracks and focuses on human eyes with approximately 30% greater precision than the α9 II.
Wide, fast, precise AF tracking
Select a subject, half-press the shutter, and the camera will track and maintain focus automatically. Turn on AF face/eye priority for seamless AI-based tracking of human, animal, or bird eyes.
The α1 features focal plane phase-detection AF that is sensitive, fast, and precise. The 50.1-MP sensor and BIONZ XR engine provide 759 selectable phase-detection points 13 covering about 92% of the image.
Next-generation 8K 14 30p recording
The new image sensor and BIONZ XR engine in the α1 deliver 8K 30p movie recording capability for extraordinary realism. Four times the resolution of 4K with full Real-time Tracking and Real-time Eye AF functionality. 8K footage is also ideally suited to flexible 4K editing.
4K movies at a high 120fps frame rate 15
The α1 supports high frame-rate internal 4K movie recording at up to 120fps, for smooth, expressive slow-motion playback at up to 5x. 10-bit 4:2:2 chroma subsampling can be used with Long-GOP or Intra (All-I) compression for outstanding image quality, while the new image sensor and BIONZ XR engine minimize image distortion.
4K with full sensor readout, no pixel binning, and 5.8K oversampling
In the Super 35 mode, approximately 2.3x the amount of data required for QFHD 4K is acquired through full-frame readout with no pixel binning, for beautifully imagery that is rich in detail.
(A) 2.3 times information
10-bit 4:2:2 chroma subsampling

The cinematic S-Cinetone look
The α1 includes the same S-Cinetone color matrix that produces beautiful color and skin tones in the VENICE, FX6, and other Cinema Line cameras. S-Cinetone delivers natural mid-tones that are essential to healthy-looking skin color, plus soft colors and gorgeous highlights, responding to a growing need for more expressive depth.
"Active Mode" image stabilization 10
A new Active Mode dedicated to movie shooting makes 5-axis optical image stabilization highly effective for handheld shooting. It uses the BIONZ XR engine's real-time processing capability to apply optimum compensation in all formats, including 4K. All of this is realized without compromising the compact size and mobility of the α system.
High-performance electronic viewfinder
The 9.44 million-dot (approx.) OLED viewfinder in the α1 offers the highest resolution in the industry at this time 6. It features 0.90x magnification with a 41 ° FOV for a clear, wide view, and an updated structure that results in a 25-mm-high eyepoint. A 240fps refresh rate with UXGA FOV is another world-first, 6 for a clear view of fast action.
Panning shots with electronic shutter
Using electronic shutter at low shutter speeds can reduce display response, making it difficult to follow fast subjects. Turn [Low Frame Rate Limit] ON to improve display response and allow panning shots.
Seamlessly switch full-frame and APS-C formats
M and S size images have the same number of pixels and AF area in the full-frame and APS-C modes, so you can switch seamlessly between full-frame [M:21MP] and APS-C [M:21MP] while shooting the same scene.
 Full Frame  APS-C
Separate settings for stills and movies
A subset of the settings now change according to the selected mode. This is ideal when you want to use different aperture, shutter speed, and other settings for shooting stills and movies.
New menu structure
Another feature requested by professional photographers and videographers: a revised menu structure for easier navigation, and touch-responsive menu operation for more intuitive control.
164 Functions are assignable to 17 custom keys as well as the front and rear dials. Independent function sets can be assigned for stills, movies and playback.
Touch menu control
Touch-responsive main and function menus with menu tabs on the left of the display, and related parameter groups and parameters on the right, make for easy navigation and tracking control.
High-reliability mechanical shutter
Shutter vibration is minimized while allowing continuous bursts at up to 10fps. The new shutter unit with advanced motor, brake, and dampers is good for more than 500,000 cycles.
Two CFexpress Type A-compatible media slots
Dual media slots support UHS-I and UHS-II SDXC/SDHC cards as well as new CFexpress Type A cards for higher overall capacity and faster read/write speeds.
High-capacity Z-series battery for extended recording
