Sony Alpha A1 Body

Sony continues to challenge the limits of conventional imaging tools with innovative technology that delivers an unprecedented combination of resolution and speed plus intuitive operation. The α1 offers new dimensions of imaging performance as well as efficient workflow, giving the user new creative freedom.

50.1 megapixel Exmor RS™ image sensor
The α1 features a full-frame stacked back-illuminated CMOS Exmor RS™ sensor with 50.1 effective megapixels and integrated memory. In addition to delivering outstanding image quality, this allows the α1 to shoot continuously at up 30 frames per second while offering fast, precise phase-detection AF and top-quality 8K movies with full-frame 8.6K oversampling for the first time in the α series. Unprecedented performance for a new era of image making.

Advanced BIONZ XR engine boosts speed by up to 8x
The α1 features a revised system architecture with greatly enhanced processing performance from image capture through all signal processing stages. Processing latency is minimized while image processing power is dramatically increased for extraordinary image quality. User interface, network, and file management processing is distributed so that fast, stress-free control response is maintained regardless of real-time processing load.

Continuous shooting at up to 30fps
High-speed readout from the 50.1-megapixel image sensor and a large buffer memory makes it possible to shoot up to approximately 165 full-frame JPEG images or 155 full-frame compressed RAW images at up to 30 frames per second with the electronic shutter while maintaining full AF and AE tracking performance. This can be a huge confidence-booster when timing is critical for sports and other moving subjects.

Silent, vibration-free electronic shutter
The electronic shutter operates silently, without mechanical noise, which can be disruptive when shooting sports or events in a quiet environment. The electronic shutter is also vibration-free, minimizing the likelihood of vibration-induced blur and further contributing to superior image quality. And since it has no moving components, the electronic shutter is much more durable than any mechanical counterpart.

Anti-flicker shooting with electronic shutter
High-speed readout from the new image sensor has made it possible to provide Anti-flicker Shooting with an electronic shutter for the first time. This enables blackout-free shooting, up to 120 AF/AE tracking calculations per second, up to 30fps continuous shooting, silent shooting, and other advantages of the electronic shutter without flicker issues when shooting under fluorescent, LED, or other flicker-prone types of artificial light.

Blackout-free shooting
The α1 viewfinder does not black out when an exposure is made, so you have an uninterrupted view that allows smooth, seamless framing and tracking, even during continuous shooting. High readout speed from the new image sensor makes it possible to refresh the live-view EVF display 240 times per second while shooting continuous bursts, overcoming the distracting time lag that is usually associated with EVF viewing.

759 point full-area phase detection AF
759 phase detection points in a high-density focal plane phase-detection AF system cover approximately 92% of the image area, ensuring accuracy and unfailing focus in scenes where focusing might otherwise be difficult. The 759-point focal plane phase-detection AF system works with a 425-point contrast AF system to ensure precise AF operation in any environment.

High resolution and sensitivity with 15-stop dynamic range
The α1 employs highly efficient noise-reduction processing to deliver extraordinary resolution from its 50.1 effective megapixel image sensor. That resolution is complemented by high sensitivity with low noise, plus approximately 15 stops of dynamic range at lower sensitivities for smooth, natural gradations from shadows to highlights.

Wide sensitivity range
Even with this sensor's high pixel count, its back-illuminated structure, gapless on-chip lenses, AR-coated seal glass and other original imaging technologies work with the new BIONZ XR image processing engine to deliver high resolution and low noise throughout a wide sensitivity range: ISO 100–32000 standard, expandable to ISO 50–102400.

5-axis optical in-body image stabilization for a 5.5-step shutter speed advantage
A high-precision stabilization unit and gyro sensors plus optimized image stabilization algorithms achieve up to a 5.5-step shutter speed advantage, maximizing the quality of the high-resolution images derived from the camera's 50.1-megapixel sensor. The α1 also features an Active Mode that offers outstanding stabilization for handheld movie shooting.

New Real-time Eye AF bird mode
In addition to Real-time Eye AF for humans and animals, the α1 employs high-level subject recognition technology to provide Real-time Eye AF for birds. Select the bird to be tracked, and the camera will automatically detect and focus on that bird's eye, whether the bird is still or in flight. Optimized algorithms ensure that tracking is maintained even if a sitting bird suddenly takes flight, or the framing suddenly changes.

Stunning realism with 8K 30p movies
For the first time in the α series, the α1 offers 8K 30p XAVC HS recording with 8.6K oversampling for extraordinary resolution and realism. Combined with superior α1 AF, gradation, and color reproduction performance, 8K resolution brings the world to life. 8K footage is also ideally suited to flexible 4K editing. Low-bit-rate proxy files with HD resolution can be recorded simultaneously with 8K.

S-Log3 and 10-bit HLG deliver extra depth
The S-Log3 gamma curve makes it possible to achieve 15+ stops of dynamic range, while the S-Gamut3 and S-Gamut3.Cine color gamut settings make it easy to match α1 footage with footage shot on the VENICE digital cinema camera, PXW-FX9, and other professional camcorders. An HLG (Hybrid Log-Gamma) picture profile is also provided, allowing direct playback on an HDR (HLG) compatible TV without the need for color grading.

4K movie recording at up to 120 frames per second
The α1 offers in-camera 4K recording at up to 120 frames per second33. Extraordinarily smooth 5x (max.) slow-motion imagery34 at 4K resolution provides new expressive capability. In addition to supporting 10-bit 4:2:2 recording, this feature can be used with efficient Long GOP inter-frame compression or high-quality Intra (All-I) intra-frame compression.

Built-in Wi-Fi supports 2 x 2 MIMO
Built-in wireless LAN allows communication on the 2.4-GHz and 5-GHz bands, the latter with 2x2 MIMO support (IEEE 802.11a/b/g/n/ac) for industry-leading speed. Dual antennas ensure reliable communication, even with the camera's durable magnesium alloy chassis. 5-GHz communication can be a notable advantage for news and sports shooters who need to deliver with reliable speed.

Fast USB Type-C and 1000BASE-T network connections
A USB Type-C® connector that supports fast SuperSpeed USB 10-Gbps (USB 3.2) data transfer is provided. This makes high-speed PC Remote (tethered) data transfer available for smooth handling of large image files. The α1 also has a built-in 1000BASE-T LAN connector for high-speed, stable data transfers, including remote shooting. FTPS (File Transfer over SSL/TLS) is supported, allowing SSL or TLS encryption for increased data security.

High-resolution viewfinder with the widest view in its class
A 9.44 million-dot (approx.) electronic viewfinder with high-definition OLED display and refined optics delivers the highest resolution in its class. It also offers 0.90x viewfinder magnification, a 41 ° diagonal FOV, and a 25-mm high eyepoint for clear, low-distortion viewing from corner to corner. This advanced viewfinder also features up to 240fps refresh rate with UXGA FOV for super-smooth display.

Two CFexpress Type A-compatible media slots
The α1 has two media slots that both 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. CFexpress Type A cards are ideally suited to high-speed continuous still shooting, as well as high-resolution, high-bitrate movie recording. Recorded stills and movies can be saved to the memory media in numerous ways, to match a wide range of applications and needs.
