Product Description
The α1 offers an extraordinary combination of high resolution and blazing speed. Ultra-fast readout from the 50.1-MP sensor allows continuous bursts at up to 30fps1 with AF and AE tracking using the electronic shutter. Perfect for sports or any situation where the critical action is over in an instant.
An interrupted blackout-free view of the subject lets you respond instantly and seamlessly. The EVF is updated at 240fps to minimize latency during continuous shooting.
(A) Blackout-free Shooting (B) Shooting with blackouts
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.
Fast sensor readout minimizes still-image distortion when using the electronic shutter. The BIONZ XRTM engine and a large buffer achieve about 1.5x less distortion than the α9 II.[1] Conventional electronic shutter [2] Anti-distortion shutter
Another world-first: flicker-free electronic and mechanical shutters. You get flicker-free shooting under fluorescent/artificial lighting with all the benefits of the electronic shutter.

A stacked architecture in this back-illuminated 50.1-MP full-frame image sensor contributes to high resolution and speed. Separate pixel and circuit layers and advanced A/D conversion mean faster processing.
The new BIONZ XR engine features advanced architecture that delivers 8x greater processing power. The result is outstanding image quality as well as improved camera interface response.
For the first time in an α camera, electronic shutter flash sync is possible thanks to high readout speed from the stacked CMOS sensor. All electronic shutter advantages remain available for flash shooting.
The world’s first 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 stops8 of dynamic range. A new image processing engine achieves even better color accuracy than previous models.
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.
Creative Look supports varied expression
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.
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.
Primarily designed for cats and dogs, this feature employs advanced subject recognition technology to reliably track and focus on animal eyes. It even works if the animal’s face is upside-down.
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.
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.
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.
