All-new architecture and BIONZ XR image processing engine

The new BIONZ XR engine features advanced architecture that delivers 8x greater processing power 2. The result is outstanding image quality as well as improved camera interface response.

Flash sync with electronic shutter

For the first time in an α camera, electronic shutter flash sync 7 is possible thanks to high readout speed from the stacked CMOS sensor. All electronic shutter advantages remain available for flash shooting.

Dual driven shutter drive for flash sync up to 1/400 s.

The world's first 6 dual driven shutter system allows flash sync up to 1/400 s., making it easier to capture dynamic action, and opening the door to new creative possibilities.

Breathtaking resolution and image quality

The new 50.1-MP Exmor RS CMOS sensor delivers high resolution and sensitivity with low noise, plus up to 15 stops 12 of dynamic range. A new image processing engine achieves even better color accuracy than previous models.

Wide ISO 100–32000 sensitivity range

Pixel Shift Multi Shooting

Despite the sensor's high pixel count, a sensitive back-illuminated structure with gapless on-chip lenses and an AR coated seal glass allows a standard ISO range of ISO 100–32000, expandable to ISO 50–102400. 11

Up to 16 images shot with precise in-body image stabilization control can be combined via computer software to create photos with up to 199 million pixels for extraordinary resolution, color, and atmosphere. 12

Creative Look supports varied expression

5-axis optical in-body image stabilization for a 5.5-step advantage

The Creative Look feature provides 10 presets that can be used unmodified or edited to create a variety of "looks" that can help creators fine-tune the mood of their stills or movies in-camera.

A precision stabilization unit and gyro sensors plus the latest image stabilization algorithms deliver a 5.5-step 9 shutter speed advantage, maximizing the quality of high-resolution images.

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.

Real-time Tracking

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.

10-bit 4:2:2 chroma subsampling

10-bit depth, 4:2:2 chroma subsampling, a high-efficiency MPEG-H HEVC/H.265 codec, intra-frame coding, and more, support flexible editing and a variety of delivery formats.

Real-time Eye AF and Real-time Tracking for movies

The BIONZ XR engine features significantly improved detection, accurately tracking human eyes at a wider range of head angles. Also available for 8K and 4K 120p recording.

S-Log for compatibility with pro cine cameras

S-Log2 and S-Log3 are included. S-Log3 provides smooth 10-bit gradations and a dynamic range of 15+ stops. S-Gamut, S-Gamut3, and S-Gamut3.Cine color spaces supported.

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.
