High-performance electronic viewfinder

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.

10-bit 4:2:2 chroma subsampling

10-bit depth, 4:2:2 chroma subsampling, a high-efficiency MPEG-H HEVC/H.265 codec, intra-frame coding, and more, support flexible editing and a variety of delivery formats.

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.

Dual driven shutter drive for flash sync up to 1/400 s.

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.

Flash sync with electronic shutter

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.

All-new architecture and BIONZ XR image processing engine

The new BIONZ XR engine features advanced architecture that delivers 8x greater processing power 2. The result is outstanding image quality as well as improved camera interface response.

Full-frame stacked 50.1-MP Exmor RS™ CMOS sensor with integral memory

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.

120 AF/AE tracking calculations per second

Fast sensor readout enables 120 AF/AE calculations per second, even during 30fps bursts, for pinpoint AF tracking precision with fast and erratic subjects. AE latency is less than 0.033 s.
(1) AF/AE calculations (2) 60 times/s (3) 20 frames/s

50.1 megapixels at up to 30 frames/second

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 3 with AF and AE tracking using the electronic shutter. Perfect for sports or any situation where the critical action is over in an instant.
