Sony continues to challenge the limits of conventional imaging tools with innovative technology that delivers an unprecedented combination of resolution and speed plus intuitive operation. The α1 offers new dimensions of imaging performance as well as efficient workflow, giving the user new creative freedom.
Next-generation 8K 30p recording
The new image sensor and BIONZ XR engine in the α1 deliver 8K 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.
4K movies at a high 120fps frame rate
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.
4K with full sensor readout, no pixel binning, and 5.8K oversampling
In the Super 35 mode, approximately 2.3x the amount of data required for QFHD 4K is acquired through full-frame readout with no pixel binning, for beautifully imagery that is rich in detail.

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.
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.
Wide, fast, precise AF tracking
The α1 features focal plane phase-detection AF that is sensitive, fast, and precise. The 50.1-MP sensor and BIONZ XR engine provide 759 selectable phase-detection points covering about 92% of the image.
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.
Improved dust- and moisture-resistant design
Sealing is provided at all body seams and the battery cover. The media slots have a double sliding cover and lock that keep water out. A lens lock button and mount cushion help too.
Separate settings for stills and movies
A subset of the settings now change according to the selected mode. This is ideal when you want to use different aperture, shutter speed, and other settings for shooting stills and movies.
New menu structure
Another feature requested by professional photographers and videographers: a revised menu structure for easier navigation, and touch-responsive menu operation for more intuitive control.
164 Functions are assignable to 17 custom keys as well as the front and rear dials. Independent function sets can be assigned for stills, movies and playback.
A brilliant blend of resolution and speed
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 color accuracy than previous models.
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 30fps2 with AF and AE tracking using the electronic shutter. Perfect for sports or any situation where the critical action is over in an instant.
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.
