Sony A1 Guides
Sony A1 Overview
The Sony a1 was announced in January 2021 and took over the title of Sony’s flagship camera from the Sony a9II. It is Sony’s most expensive camera to-date.
With a 50.1 megapixel stacked sensor and 8k video, the Sony a1 has been designed to do it all and without compromise.
It’s the ultimate hybrid shooter, and without doubt a flagship camera in the truest sense.
Here are some of the things that the a1 shares in common with the a9II:
- Body design
- NP-FZ100 battery
- 5-axis stabilization with 5.5Ev of compensation (CIPA)
- 1,440,000 dots LCD with adjustable angle (up 107 degrees, down 41 degrees)
- Multi Interface Shoe (MI Shoe) with a Digital audio interface
And here are the new features that the a1 gains:
- New 50.1-megapixel full-frame stacked Exmor RS™ CMOS image sensor in combination with an upgraded BIONZ XR™ imaging processing engine with eight times more processing power
- Blackout free continuous shooting at up to 30 frames per second
- Fast sensor readout enables up to 120 AF/AE calculations per second, double the speed of the Alpha 9 II, even during 30fps continuous shooting
- Bright and large 0.64-type 9.44 million-dot (approx.) OLED Quad-XGA electronic viewfinder with the world’s first refresh rate of 240 fps
- World’s first anti-flicker shooting with both mechanical and electronic shutter
- Electronic shutter flash sync up to 1/200 sec.
- World’s fastest mechanical shutter flash sync up to 1/400 sec.
- 8K 30p 10-bit 4:2:0 XAVC HS video recording with 8.6K oversampling for extraordinary detail and resolution, in addition to 4K 120p 10-bit 4:2:2 movie shooting capabilities
- Improved Real-time Eye AF (autofocus) for humans and animals, and new Real-time Eye AF for birds
- S-Cinetone color matrix as seen in FX9 and FX6 to deliver expressive cinematic look
- Wi-Fi, SuperSpeed USB 10Gbps, 1000BASE-T Ethernet and more
Please visit my Sony A1 vs A9 II Comparison for a complete in-depth guide to the differences between these two amazing cameras.
The a1 can quite easily replace three camera bodies (a9II, a7R IV, a7S III) with one, and I know of many shooters already planning to do just this. The a1 is the ultimate hybrid camera at this moment in time.
I own both the a9 and a7R IV myself, and I have to admit to being very tempted to trade them in for the a1. But I will wait for some real-world reviews before I take the plunge!
