Overview

50.1 megapixel¹ 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 30 fps

High speed readout from the 50.1-megapixel image sensor and a large buffer memory make 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.

Silent, vibration-free electronic shutter

The electronic shutter operates silently, without mechanical noise that can be disruptive when shooting sports or events in a quiet environment. The electronic shutter is also vibration-free, minimising the likelihood of vibration-induced blur and further contributing to superior image quality. And since it has no moving components the electronic shutter is much more durable than any mechanical counterpart.

Anti-flicker shooting with electronic shutter

High-speed readout from the new image sensor has made it possible to provide Anti-flicker Shooting with an electronic shutter for the first time¹⁰. This enables blackout-free shooting, up to 120 AF/AE tracking calculations per second, up to 30 fps continuous shooting¹¹, silent shooting, and other advantages of the electronic shutter without flicker issues when shooting under fluorescent, LED or other flicker-prone types of artificial light.

Electronic shutter flash sync + high-speed mechanical sync

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 are available at up to 1/200 sec. If you need even more speed a new mechanical shutter system allows flash sync up to 1/400 sec. (1/500 sec. APS-C), making it easier to capture dynamic action and opening the door to new creative possibilities.

High resolution and sensitivity with 15-stop dynamic range

The α1 employs highly efficient noise reduction processing to deliver extraordinary resolution from its 50.1 effective megapixel image sensor. That resolution is complemented by high sensitivity with low noise, plus approximately 15 stops of dynamic range at lower sensitivities for smooth, natural gradations from shadows to highlights.

Wide sensitivity range

Even with this sensor’s high pixel count, its back-illuminated structure, gapless on-chip lenses, AR-coated seal glass and other original imaging technologies work with the new BIONZ XR image processing engine to deliver high resolution and low noise throughout a wide sensitivity range: ISO100~32000 standard, expandable to ISO50~102400

Use Creative Look to create moods in camera

A selection of new Creative Looks makes it easy to create interesting moods for stills and movies right in the camera. 10 Creative Looks are provided as presets with different combinations of colour, colour depth, brightness, contrast, sharpness, and more. The presets can be used as they are or customised by the user. Customised Creative Looks can be stored as Custom Looks for later recall and use.

5-axis optical in-body image stabilization for a 5.5-step shutter speed advantage

A high-precision stabilization unit and gyro sensors, plus optimized image stabilization algorithms, achieve up to a 5.5-step shutter speed advantage, maximizing the quality of the high-resolution images derived from the camera’s 50.1-megapixel sensor. The α1 also features an Active Mode that offers outstanding stabilization for handheld movie shooting.

New Real-time Eye AF bird mode

In addition to Real-time Eye AF for humans and animals, the α1 employs high-level subject recognition technology to provide Real-time Eye AF for birds. Select the bird to be tracked, and the camera will automatically detect and focus on that bird’s eye whether the bird is still or in flight. Optimized algorithms ensure that tracking is maintained even if a sitting bird suddenly takes flight, or the framing suddenly changes.

Tenacious Real-time Tracking

The α1 includes AI-based Real-time Tracking that automatically maintains accurate focuswhile the shutter button is half-pressed. A newly developed subject recognition algorithm uses colour, pattern (brightness), and subject distance (depth) data to process spatial information in real time at high speed. α1 Real-time Tracking is faster, more accurate, and more tenacious than ever before.

759 point full-area phase detection AF

759 phase detection points in a high-density focal plane phase-detection AF system cover approximately 92% of the image area, ensuring accuracy and unfailing focus in scenes where focusing might otherwise be difficult. The 759-point focal plane phase-detection AF system works with a 425-point contrast AF system to ensure precise AF operation in any environment.

Stunning realism with 8K 30p movies

For the first time in the α series, the α1 offers 8K 30p XAVC HS recording with 8.6K oversampling for extraordinary resolution and realism. Combined with superior α1 AF, gradation, and colour reproduction performance, 8K resolution brings the world to life. 8K footage is also ideally suited to flexible 4K editing. Low-bit-rate proxy files with HD resolution can be recorded simultaneously with 8K. 8K 4:2:2 10bit recording is available as of α1 Ver. 1.3, allowing more varied expression and high-level editing capability at 8K resolution.

4K movie recording at up to 120 frames per second

The α1 offers in-camera 4K recording at up to 120 frames per second. Extraordinarily smooth 5x (max.) slow-motion imagery at 4K resolution provides new expressive capability. In addition to supporting 10-bit 4:2:2 recording, this feature can be used with efficient Long GOP inter-frame compression or high-quality Intra (All-I) intra-frame compression.

Full pixel readout without binning for high-res 4K

Full frame and Super 35 formats can be selected for 4K movie recording. Full pixel readout in the Super 35 mode (approx. APS-C 16:9), without the need for pixel binning, makes it possible to condense approximately 2.3 times the amount of data required for 4K movies, resulting in high-resolution, high-detail 4K with minimal moiré and jaggies. Bit rates up to 600 Mbps can be used for 4K XAVC HS, XAVC S, and XAVC S-I recording.

S-Log3 and 10-bit HLG deliver extra depth

The S-Log3 gamma curve makes it possible to achieve 15+ stops of dynamic range, while the S-Gamut3 and S-Gamut3.Cine colour gamut settings make it easy to match α1 footage with footage shot on the VENICE digital cinema camera, PXW-FX9, and other professional camcorders. An HLG (Hybrid Log-Gamma) picture profile is also provided, allowing direct playback on an HDR (HLG) compatible TV without the need for colour grading.

16-bit RAW output

The α1 allows 16-bit RAW output to an external recorder via HDMI for maximum post-production flexibility. Full-frame 4332 x 2448 16-bit image output easily covers 4096 x 2048 DCI-4K, with a choice of frame rates (59.94p/50p/29.97p/25p/23.98p) and colour spaces. It is also possible to output RAW via HDMI while recording XAVC HS 4K, XAVC S 4K, or XAVC S-I 4K to internal card media. Proxy recording is also available.

Effective heat-dissipation for extended recording

A newly developed heat dissipating structure keeps image sensor and image processing engine temperatures within their normal operating range, preventing overheating while maintaining compact body dimensions. This makes it possible to record 8K/30p or 4K/60p videos10-bit 4:2:0 video continuously for more than 30 minutes.

S-Cinetone for that expressive cinematic look

The α1 includes S-Cinetone, the same colour matrix that produces the highly regarded FX9 and FX6 colour and skin tones. Based on technology acquired through development of Cinema Line cameras such as FX9, S-Cinetone delivers natural mid-tones that are essential to healthy-looking skin colour, plus soft colours and gorgeous highlights. S-Cinetone responds to a growing need for more expressive depth.

Pan shots with electronic shutter

Using electronic shutter at low shutter speeds can reduce display response, making it difficult to follow fast subjects. Turn [Low Frame Rate Limit] ON when shooting at a shutter speed lower than 1/60 to insert blackout frames at an appropriate frame rate to improve display response and make it easier to follow the subject without display lag²².

Seamlessly switch full-frame and APS-C formats

M and S size images have the same number of pixels in the full-frame and APS-C modes²³, so you can switch seamlessly between full-frame [M:M21] and APS-C [M:M21], for example, while shooting the same scene. And because the full array of 759 phase detection points is available in APS-C mode as well as full-frame mode, you get the same smooth AF performance.

[1] Full Frame [2] APS-C

Independent still and movie settings

A subset of the camera’s shooting settings now change according to the selected shooting mode.
