Introduction
The Sony Alpha 1 II, or Sony A1 II for short, is a brand new flagship 35mm full-frame mirrorless camera which boasts all of Sony’s latest cutting-edge still photography and video technologies.
This camera has a 35mm full-frame stacked Exmor RS CMOS sensor offering a resolution of 50.1 megapixels. The native sensitivity range is ISO 100-32,000, which can be expanded down to ISO 50 and up to ISO 102,400.
For video, it offers 8K/30p 10-bit 4:2:0 XAVC HS video recording with 8.6K oversampling, up to to 4K 120p 10-bit 4:2:2 (with a 10% crop), and Full HD at 240fps movie shooting capabilities, and it can also output 16-bit Raw video over HDMI.
The A1 II has a blackout-free 240fps EVF with 9.44M dots, 4-axis LCD screen, 8.5-stops of in-body image stabilization (IBIS), dust and moisture resistance, and dual BIONZ XR processors which provide the latest AI-based Real-time Recognition AF system.
The AF system has 759 on-sensor phase detection points that covers approximately 92% of the image area and can auto-focus down to EV-4 in low light. The new A1 II now has a dedicated AI chip that provides Subject Recognition AF modes for stills and movies, including a new Auto subject mode.
There are special Pre-capture and Continuous Shooting Speed Boost modes, the latter allowing you to select 30fps at the press of a button, if you’re not already shooting in it.
The new Composite Raw shooting mode takes up to 32 images to reduce noise through Sony’s Imaging Edge software, with handheld shooting possible. It also adds a brand new Noise Reduction pixel shift mode which produces super low-noise composite images using the same process.
Other key specs include 30fps burst shooting, weather-sealing, electronic shutter flash sync, a new 2.5Gbps wired LAN port, up to 530 shot battery life, and dual memory card slots.
It sits right at the top of the Sony Alpha range, above the 61 megapixel landscape-focused A7R V, 120fps sports-orientated A9 III and the 4K video-centric A7S III, with the cheaper A7 IV all-rounder and the super-compact A7C II positioned below those three models.
The Sony A1 II is priced at £6300 / €7500 / $6500 body-only in the UK, Europe and USA respectively.
It’s compatible with the VG-C5 vertical grip which is priced at £390 / $400 / €450.
Image Quality
All of the sample images in this review were taken using the 50 megapixel Extra Fine JPEG setting, which gives an average image size of around 30Mb.
The Sony A1 II produced images of outstanding quality during the review period.
The Alpha 1 II has an extensive and very usable expanded ISO range of 50-102400. When shooting JPEG, ISO 50-00 is virtually noise-free, while ISO 12800 and 25600 produce more than acceptable results, and even ISO 51200 and 102400 are OK for emergency use.
The long exposure photograph was excellent, with the maximum shutter speed of 30 seconds and the Bulb mode offering lots of scope for creative night photography.
The effective Dynamic Range Optimizer function extracts more detail from the shadow and highlight areas in an image, without introducing any unwanted noise or other artifacts.
The various Picture Profiles quickly produce special looks for your JPEG files that would otherwise require you to spend a lot of time in the digital darkroom, while the Creative Looks provide a quick and easy way to tweak the camera’s JPEG and Raw image output.
Noise
There are 12 ISO settings available on the Sony A1. Here are some 100% crops which show the noise levels for each ISO setting for the JPEG format.
File Quality
The Sony A1 has 4 different JPEG image quality settings available, with Extra Fine being the highest quality option. Here are some 100% crops which show the quality of the various options, with the file size shown in brackets.
| Extra Fine (23.2Mb) | Fine (11Mb) |
 |  |
| Standard (6.8Mb) | Light (4.13Mb) |

Pixel Shift Multi Shoot
In the Pixel Shift Multi Shooting mode, the Sony A1 shoots either 4 or 16 uncompressed RAW images whilst shifting the image sensor either one pixel or a 1/4 of a pixel at a time. You can then generate images with a higher resolution than is possible with regular shooting by combining the RAW images on a computer using the Imaging Edge (Remote/Viewer/Edit) application.
Dynamic Range Optimizer
D-Range Optimiser (DRO) is Sony’s solution to improve shadow detail in photos taken in contrasty light. There are 5 different levels and an Auto option.
Creative Looks
There are 10 Creative Look preset effects that you can use to change the look of your images. They can be applied to both JPEGs and Raw files.
Picture Profiles
The Sony A1 offers a range of 11 creative Picture Profiles, which can only be selected when JPEG is set as the image quality option.
