Sony A1 II Key Features

At its heart, the Sony A1 II features a retuned version of the Sony A1's 50.1MP stacked Exmor RS CMOS sensor, paired with Sony's latest processing engine, the BIONZ XR processor and a dedicated AI processing unit. This combination enables advanced subject recognition and real-time tracking with settings for a wide range of subjects including Human, Animal, Bird, Animal/Bird, Insect, Car, Train, Airplane. Notably, there's also an Auto setting that instructs the camera to look for any of the detectable subjects. The AI system includes pose estimation, which predicts the position of a subject's eyes even when they are partially obscured or turned away from the camera. According to Sony, the A1 II's eye detection is up to 30% more accurate than the A1's.

For photographers, the camera delivers 50.1MP stills with 15 stops of dynamic range, capturing fine detail and colour with reduced noise at mid-to-high ISO settings. The A1 II gives blackout-free shooting at up to 30fps with full autofocus and auto-exposure (AF/AE) tracking and performs up to 120 autofocus and autoexposure calculations per second. There's also Pre-Capture mode that allows photographers to capture images for up to one second before the shutter release is pressed home (it records while the shutter button is half-pressed).

No camera is complete without in-camera image stabilisation (IBIS) and Sony claims the A1 II gives up to 8.5 stops of shutter speed compensation at the centre of the frame, dropping to 7-stops around the edges.

Naturally, Sony's flagship camera has some impressive video features. These include 8.6K oversampling for 8K 30p footage with full-width, full-pixel read-out, 4K 120p recording and Super 35 mode. There's also Real-time subject recognition in movie mode and in-body image stabilisation. The A1 II also has Auto Framing which crops the video but follows the subject around the frame, keeping it at the centre of attention.

Build and Handling

Sony has refined the A1 II’s ergonomics compared to the original A1, borrowing from the Sony A9 III for a more comfortable and secure grip. The grip feels chunkier than the older camera's, but the A1 II still only weighs 743g with a battery and memory card, 658g, body-only.

The redesigned body has an improved shutter button position and a new C5 custom button on the front. By default, this button acts as a speed boost, ramping the continuous shooting rate from whatever is selected to the 30fps maximum. That's a useful option when the action develops quickly.

There are also lock buttons the exposure mode, drive mode and top-rear dials to prevent accidental changes.

The 0.64-inch electronic viewfinder (EVF) has an excellent 9.44 million-dot OLED display with 0.9x magnification and blackout-free operation. Meanwhile, the 3.2-inch 2,095,104-dot touchscreen is mounted on a four-axis multi-angle bracket that is useful when shooting in vertical and horizontal orientation.

For professionals on the move, the A1 II introduces faster-wired image transfer, improved FTP capabilities and integration with Sony’s Creators’ Cloud for automatic file uploads to services like Adobe Lightroom or Google Drive. It's even possible to use the new microphone system to record, tag and transcribe audio into metadata, streamlining workflows.

Performance

After shooting with the Sony A1 II in a studio, I’m looking forward to taking it outside and shooting a wider range of subjects. It’s immediately clear that the A1 II’s autofocus system is fast and accurate, while the human eye detection does a great job with moving subjects, even when the yes is partially obscured.

Early verdict

The Sony A1 II builds on the solid foundation of its predecessor, incorporating advanced AI-driven technologies and practical improvements that cater to professional photographers and videographers. It doesn't make any really groundbreaking introductions itself but incorporates Sony's latest technology to make an attractive all-rounder with an impressive autofocus system, high-resolution sensor and versatile shooting capabilities.
