Sony A1 II Review

The next-generation flagship mirrorless camera from Sony faces high expectations, thanks to the success of the original groundbreaking Sony A1. To build on this impressive legacy, the Sony A1 II brings a host of upgrades and refinements, both inside and out.

Watch the Sony A1 II video review here by Gareth Evans

The original A1 was Sony’s first flagship mirrorless camera, combining the best technologies available at its January 2021 launch. However, much has changed since then, and the new flagship model reflects those advancements, combining the very latest hybrid technologies from the Sony E camera range.

Join us as we explore what’s new in our Sony A1 II review, watch Gareth’s hands-on video, enjoy his sample images, and compare specs between the two generations in our comparison table to discover the full impact of this release for your work.

When was the Sony A1 II released and how much is it?

The Sony A1 II was released on 19th November 2024, and costs £6299.00 vs £5,879.00 for the outgoing model. It draws on technology first introduced in revolutionary models like the A9 III and the ultra high-resolution A7R V, with a dizzying combination of resolution, speed, and features never seen before in a Sony camera.

Mirrorless flagships differ slightly from their DSLR counterparts, which often separate high resolution from high speed. As a mirrorless-only manufacturer, Sony has embraced this combination with the A1 series. Let’s take a closer look at the core specs and what it offers.

Sony A1 II key features

As expected, the Sony A1 II is packed with advanced technology in a refined body design, that weighs only 658g (excluding memory card and battery). Below is an overview of its most notable features and specifications, which are aimed at advanced enthusiasts and professionals:

• 50.1 MP Exmor RS stacked sensor and BIONZ XR processor
• Improved colour accuracy with low noise, even at mid to high ISOs
• Enhanced 8.5-stop maximum in-body stabilisation
• New Composite RAW options to capture 200 MP resolution or reduce noise
• Real-time focusing powered by a dedicated AI chip for precise tracking
• Tracks subjects like animals, birds and cars in photo and video modes
• Burst shooting at 30fps with blackout-free view and full AF/AE tracking
• Pre-Capture mode allows you to capture frames before fully pressing the shutter
• 8K 30p and 4K up to 120p video capture with 4:2:2 10-bit recording
• Cinematic capabilities with S-CINETONE, LUT imports, and S-LOG 3 for customised video grading
• Video stability with Dynamic Active and Breathing Compensation
• Ergonomic improvements such as a 4-axis multi-angle monitor, 9.44M-dot EVF with a deeper eyecup, and a redesigned grip
• Enhanced connectivity, battery performance, and anti-dust system for improved usability
• Expanded customisation options for shooting and reviewing content
• Dedicated voice memo microphone
• Includes BC-ZD1 dual charger for simultaneous battery charging in 155 minutes

There’s a lot to unpack here, so let’s dive deeper into some of these features and see how they can impact the quality of your results.

Image quality upgrades

Sony has introduced a dedicated AI processing unit and refined the sensor-shift mechanism with 5-axis stabilisation, enhancing autofocus, sharpness, and overall image quality. The AI chip recognises and accurately tracks a wider range of subjects, improves Auto White Balance (AWB) in difficult lighting, and delivers more precise AF for these subjects:

• Auto
• Human
• Animal
• Bird
• Insect
• Car
• Train
• Airplane
• Auto
• Human
• Animal
• Bird
• Insect
• Car
• Train
• Airplane

The AI system analyses and recognises human subjects, even in challenging lighting conditions, detecting features such as the head, face, eyes, and body poses whether partially hidden, small in the frame, or backlit. Human eye recognition has been improved by around 30%, and bird recognition accuracy has been enhanced by 50% for the mark II camera.

Human eyes are reliably tracked even if the subject is wearing glasses or partially obscured by clothing, and the camera covers 92% of the image area with 759 high-density phase-detection AF points, ensuring robust autofocus coverage and accuracy, including when shooting in APS-C crop mode.

This evolved AF system offers exceptional imaging intelligence across multiple genres, whether you capture sports and action, portraits and events, wildlife or video.

Improved stabilisation

If you shoot handheld the A1 II has you covered with enhanced IBIS for up to 8.5-stops in the centre of the frame and 7-stops compensation in the periphery, delivering a signifiant upgrade compared to its predecessor. This can make a huge difference allowing for slower shutter speeds with reduced noise from lower ISO values, while maintaining sharpness.

New Pre-Capture and Continuous Speed Boosting features

The Alpha 1 II introduces Sony’s Pre-Capture and Continuous Speed Boosting features, helping photographers capture the perfect frame in RAW or JPEG. Pre-Capture buffers images as soon as you half-press the shutter, recording 0.03 to 1 second of full-resolution images before you fully press the shutter.

This ensures that you can better capture the decisive moment during fast or unpredictable action.

With Continuous Speed Boost, users can assign a custom button to temporarily increase burst shooting speed while the button is pressed, allowing for a brief boost in capture rate without ending up with thousands of unnecessary shots.

These features are accompanied by two new Composite RAW options, which we explore next.

New Composite RAW

With the A1 II users can select from two types of Composite RAW images. One delivers remarkable 200 megapixel resolution results, and the other reduces noise for cleaner images. These options are ideal for capturing product photos, still life, and other static subjects where enhanced resolution or noise control are key.

Professional video capabilities

The A1 II is a hybrid flagship, allowing you to capture stunning 8K video at up to 30p or 4K at up to 120p with a professional 4:2:2 10-bit codec. You can achieve a cinematic look straight out of the camera using the S-CINETONE colour profile, or customise your images by importing your own LUTs directly into the camera.

Recording in S-LOG 3 offers the greatest flexibility in post-production, delivering footage with a wide dynamic range with malleable highlights and shadows. Sony has also enhanced recording stability and smooth transitions with Dynamic Active and Breathing Compensation, available exclusively when using Sony E mirrorless lenses.

Ergonomic and design updates

The A1 II body has received several refinements in its second generation, including an upgraded 3.2-inch 4-axis multi-angle 2.1-million-dot monitor. The ultra-high-resolution 9.44-million-dot EVF is now complemented by a deeper FDA-EP21 eyepiece cup to reduce light leakage, while the button layout has also been improved.

Notable additions include a new front C5 custom button, a Stills/Movie/S&Q dial, and a deeper body grip for enhanced handling, creating a smoother shooting experience overall. Sony has even refined the shutter button, positioning it more naturally to accommodate the subtleties of the new Pre-Capture mode.

Dual SD (UHS-II) / CFexpress Type A memory card slots, enable the use of Sony and other brand memory cards.

Connectivity and interface

The A1 II body offers extensive customisation options, Sony’s cable and battery-free Multi Interface Shoe, and several upgrades such as a dedicated voice memo microphone, 2.5GBASE-T Ethernet, and more.

This allows the addition of microphones such as the ECM-M1 Shotgun Microphone, flashguns including the second-gen. HVL-F60RM2 and much more.

It’s designed to support both stills and video shooting, followed by seamless data sharing, with a range of connectivity options including a mic terminal, headphone/mic 3.5mm stereo minijack terminals and Bluetooth remote control.

Three FTP transfer modes ensure fast content delivery in various ways, while live USB streaming is available in 4K, with RTMP, RTMPS, and SRT support. Support for Sony’s remote camera tool offers camera sync, remote shooting and Wake on LAN, and other convenient remote features.
