Used Sony a1 Mirrorless Camera Body

Sony's flagship full-frame mirrorless camera, the Sony α1 offers an extraordinary combination of high resolution and blazing speed in a lightweight, magnesium alloy weather sealed body. The newly designed 50.1MP full-frame Exmor RS BSI CMOS sensor and BIONZ XR processing engine gives you incredible 30fps continuous shooting at full-resolution, 8K 30p and 4K 120p video recording and sensitivity up to ISO 102400 for amazing low-light shooting. The Sony a1 includes a 759-point hybrid AF system, which offers advanced subject tracking and Real-time Eye AF on humans and animals, including a dedicated bird mode. There is a new 9.44m-dot OLED EVF and 3-inch tilting touchscreen LCD, plus dual memory card slots which support CFexpress Type A or SD memory cards. The built-n 5-Axis SteadyShot Image Stabilisation compensates for any shake during handheld shooting of stills and video. There is also an Active IS mode for video to give even more precise stabilisation.

Full-frame stacked 50.1 MP Exmor RS CMOS 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
The α1 features a revised system architecture with greatly enhanced processing performance from image capture through all signal processing stages. Processing latency is minimised 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.

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 colour 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.

4K movie recording at up to 120 frames per second
The α1 offers in-camera 4K recording at up to 120 frames per second. Extraordinarily smooth 5x (max.) slow-motion imagery 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.

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 colour gamut settings make it easy to match α1 footage with 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 colour grading.

High resolution viewfinder
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 25mm high eyepoint for clear, low-distortion viewing from corner to corner. This advanced viewfinder also features up to 240 fps refresh rate with UXGA FOV for super-smooth display.

Touch operation
A revised menu structure provides easier navigation, and touch-responsive menu operation offers faster, more intuitive control. All main and function menus are touch responsive. Even more intuitive control is provided by Touch Focus and Touch Tracking. With Touch Tracking enabled, all you have to do is touch a subject on the monitor to initiate Real-time Tracking for that subject, for both stills and movies.

5-axis optical in-body image stabilisation for a 5.5-step advantage
A precision stabilisation unit and gyro sensors plus the latest image stabilization algorithms deliver a 5.5 step shutter speed advantage, maximising the quality of high-resolution images.

Blackout-free for an uninterrupted view
An interrupted blackout-free view of the subject lets you respond instantly and seamlessly. The EVF is updated at 240 fps to minimise latency during continuous shooting.

Silent, vibration-free shutter
A silent electronic shutter provides greater opportunities for shooting sports and other subjects where noise is not tolerated. Vibration-free operation contributes to high image quality.

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.

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 birds28. 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.

Real-time Tracking
The α1 includes AI-based Real-time Tracking that automatically maintains accurate focuswhile the shutter button is half-pressed. A newly developed subject recognition algorithm uses colour, pattern (brightness), and subject distance (depth) data to process spatial information in real time at high speed. α1 Real-time Tracking is faster, more accurate, and more tenacious than ever before.

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 ISO100 ~ 32000 sensitivity range
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 ISO100~32000, expandable to ISO50~102400.

Silent, vibration-free electronic shutter
The electronic shutter operates silently, without mechanical noise that can be disruptive when shooting sports or events in a quiet environment. The electronic shutter is also vibration-free, minimising 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.

Reliable in demanding situations
improved dust and moisture resistance, new high-reliability mechanical shutter with 500,000 shutter cycle and superspeed USB-C 3.2 type connector supporting power delivery.

Built-in Wi-Fi supports 2x2 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.
