The Alpha 1 delivers an unprecedented combination of resolution, speed and video performance, empowering professionals with a new high-resolution 50.1-megapixel full-frame image sensor, high-speed shooting at up to 30 Frames per second, 8K 30p video and more.

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 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.

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.


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.

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 of dynamic range. A new image processing engine achieves even better colour accuracy than previous models.

Real-time Eye AF for birds
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
