Alpha 1 with superb resolution and speed
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 30fps with AF and AE tracking using the electronic shutter. Perfect for sports or any situation where the critical action is over in an instant.
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.
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.
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, colour, and atmosphere.

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.
The new image sensor and BIONZ XR engine in the α1 deliver 8K (7680x4320) 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.
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 α1 includes the same S-Cinetone colour matrix that produces beautiful colour and skin tones in the FX9, FX6, and other Cinema Line cameras. S-Cinetone delivers natural mid-tones that are essential to healthy-looking skin colour, plus soft colours and gorgeous highlights, responding to a growing need for more expressive depth.
The 9.44 million-dot (approx.) OLED viewfinder in the α1 offers the highest resolution in the industry at this time. 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, for a clear view of fast action.
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). Dual antennas ensure reliable communication.
A USB Type-C® connector that supports fast USB 3.2 SuperSpeed USB 10-Gbps data transfer, making fast PC Remote (tethered) data transfer available for smooth handling of large files.
A built-in connector for wired 1000BASE-T connection enables fast, stable data transfers at gigabit speeds. FTPS is supported, allowing SSL or TLS encryption for greater security.
