The most technologically advanced, innovative camera that Sony has ever released, the Alpha 1 combines high-resolution and high-speed performanceat a level that has never been accomplished in the world of digital cameras. With a brand new 50.1-megapixel full-frame stacked Exmor RS™ image sensor, up to 120 AF/AE calculations per second, 8K 30p 10-bit 4:2:0 video and much more, the Alpha 1 will allow creators to capture what they’ve never been able to before.

"We are always listening to our customers, challenging the industry to bring
new innovation to the market that goes far beyond their expectations.” said
Yann Salmon Legagneur, Director of Product Marketing, Digital Imaging, Sony
Europe. “Alpha 1 breaks through all existing boundaries, setting a new bar for
what creators can accomplish with a single camera. What excites us the most
– more than the extensive product features – is Alpha 1's ability to capture
that which has never been captured before. This camera unlocks a new world
of creative possibilities, making the previously impossible now possible.”
The newly developed image sensor is built with integral memory and paired
with an upgraded BIONZ XR imaging processing engine, making it capable of
shooting 50.1-megapixel images continuously at an astounding 30fps with up
to 120 AF/AE calculations per second. The Alpha 1’s shooting capabilities are
further enhanced by a 9.44 million dot OLED Quad-XGA electronic viewfinder,
with a refresh rate of up to 240 fps[xiv], ensuring no black out. Additionally,
for the first time in an Alpha series camera, 8K 30p 10-bit 4:2:0 video is
available. The Alpha 1 is also capable of 4K 120p / 60p 10-bit 4:2:2 recording
and includes S-Cinetone colour. The Alpha 1 is also packed with features that
support field professionals with faster workflow, including 3.5 times faster
wireless FTP transfer speed[xv] and more.

Unprecedented Resolution and Speed

Continuous Shooting at Up to 30 Frames Per Second

The Alpha 1 captures moments that would otherwise be lost thanks to its
high-speed performance, providing any photographer the speed they require
to capture fast-moving objects. High speed readout from the 50.1-megapixel
image sensor and a large buffer memory make it possible to shoot up to 155
full-frame compressed RAW images[xvi] or 165 full-frame JPEG images[xvii]at
up to 30 frames per second with the electronic shutter while maintaining full
AF and AE tracking performance[xviii].
At an astonishing calculation speed of up to 120AF/AE per second, the Alpha
1 can maintain focus with high accuracy even for fast moving subjects. It can
automatically adjust exposure, even with sudden changes in brightness, with
an AE response latency as low as 0.033 secondsii.
Advanced Electronic Viewfinder with the World’s Firstiv Refresh Rate of 240 fps
Complimenting the camera’s ability to capture images at an unprecedented
speed, the Alpha 1 viewfinder features the world’s firstiv240 fps refresh ratexiv,
for a super-smooth display. The viewfinder does not black out when an
exposure is made to offer an uninterrupted view and allow for seamless
framing and tracking, even during continuous shooting. The 9.44 million-dot
(approx.), 0.64 type Quad-XGA high-definition OLED display and refined
optics deliver the highest resolution in its classiv. It also offers 0.90x[xix]
viewfinder magnification, a 41° diagonal FOV, and a 25mm-high eyepoint for
clear, low distortion viewing from corner to corner.

Advanced Autofocus

Sony continues to push the boundaries of autofocus technology with the
introduction of the Alpha 1, which can easily track complex, fast-moving
subjects with high precision. The camera features 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
environments where focusing might otherwise be difficult.
Sony’s advanced Real-time Eye AF improves detection performance by 30%
over the previous systemi, thanks to the powerful image processing engine,
BIONZ XR. It ensures accurate, reliable detection, even when the subject’s
face looks away. In addition to improved Real-time Eye AF for humans and
animals, the Alpha 1 employs high-level subject recognition technology to
provide Real-time Eye AF for birdsxi, a first in an Alpha series camera.
Optimised algorithms ensure that tracking is maintained even if a sitting bird
suddenly takes flight, or the framing suddenly changes[xx].
The Alpha 1 also features AI-based Real-time Tracking that automatically
maintains accurate focus. A subject recognition algorithm uses colour, pattern
(brightness), and subject distance (depth) data to process spatial information
in real time at high speed.

Silent, Vibration-free Electronic Shutter

High-speed readout from the new image sensor has made it possible to
reduce rolling shutter by up to 1.5 times when shooting stills, compared to
the Alpha 9 II. It also offers silent anti-flicker continuous shooting with an
electronic shutter for the first timev in the world. The electronic shutter[xxi]
operates silently, without mechanical noise, and is vibration-free. Stress-free
continuous shooting is now possible even when shooting in challenging
lighting situations with florescent or other flicker-prone types of artificial
lighting. And for the first time in an Alpha camera, electronic shutter flash
sync up to 1/200 sec[xxii] is possible. The advantages of the electronic
shutter advantages can now come to life even when using flash for broadly
expanded shooting versatility.

Dual Driven Shutter System for 1/400 Flash Sync

The Alpha 1 boasts the world’s fastest flash sync speedv of 1/400 sec. with
mechanical shutter, making it even easier to capture dynamic action. In
addition to a carbon fibre shutter curtain, the Alpha 1 features the newly
developed dual driven shutter system utilising spring and electromagnetic
drive actuator, offering high durability and lightness at the same time.

High Resolution Shooting Enhancements

Even with this sensor’s high pixel count, the Alpha 1 offers high sensitivity
with low noise, plus 15+ stops of dynamic range for video and 15 stops for
stills, for smooth, natural gradations from shadows to highlights thanks to its
cutting-edge processing system, throughout a wide ISO sensitivity range of
100-32,000 (expandable to 50-102,400, when shooting stills).
Additionally, the new camera features an evolved Pixel Shift Multi Shooting
mode that composites up to 16 full-resolution images. In this mode, the
camera precisely shifts the sensor in one pixel or half-pixel increments to
capture 16 separate pixel-shifted images containing a total of 796.2 million
pixels of data, which are then composited into a 199 million pixel (17,280 x
11,520 pixels) image using Sony’s Imaging Edge™ desktop application. With
a flash sync of up to 1/200 sec. in this mode, it is ideal for photographing
architecture, art or any other still life subject with a level of detail and colour
accuracy that is simply stunning.

Professional Video Quality

8K High-Resolution Movie Shooting

For the first time in an Alpha camera, the Alpha 1 offers 8K 30p 10-bit 4:2:0
XAVC HS recording with 8.6K oversampling for extraordinary resolution.
Combined with Sony’s acclaimed autofocus technology, gradation and colour
reproduction performance, the Alpha 1 will help the user realise their
creative vision with the finest detail. It’s 8K footagecan also be used for
flexible 4K editing during post-production.

Supporting Various Video Formats for Professionals

The Alpha 1 offers in-camera 4K recording at up to 120 frames per secondviii
which allows the user to shoot up to 5X slow-motion video[xxiii]. 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
The Alpha 1 features S-Cinetone, the same colour matrix that produces the
highly regarded FX9 and FX6 colour and skin tones. It delivers natural midtones,
plus soft colours and gorgeous highlights to meet a growing need for
more expressive 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 Alpha 1 footage with video shot on
VENICE cinema camera, FX9 and other professional cinema cameras.

Heat-dissipating Structure

A unique 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 video continuously for approximately 30


Supporting Hand-held Shooting

A high-precision stabilisation unit and gyro sensors, plus optimised image
stabilisation algorithms, achieve up to a 5.5-step shutter speed advantage,
maximising the quality of the high-resolution images derived from the
camera’s 50.1-megapixel sensor. The Alpha 1 also features an Active
Mode[xxv] that offers outstanding stabilisation for handheld movie shooting.
When using Sony’s desktop applications Catalyst Browse or Catalyst
Prepare[xxvi] for post-production, an accurate image stabilisation function is
available which utilises metadata generated by the camera's built-in gyro.
Other features that the Alpha 1 offers include; 16-bit RAW output[xxvii] to an
