Rent NowThe Sony a1 is Sony’s flagship full-frame mirrorless camera, a true no-compromise design built to be the one camera that does it all. It combines high-resolution stills capability, professional-grade video, exceptional speed, and advanced connectivity into a single body, aimed at working professionals across sports, wildlife, wedding, studio, portrait, and video-focused disciplines who might otherwise need to choose between separate resolution-focused and speed-focused cameras.
At the core of the a1 is a 50.1MP full-frame stacked Exmor RS CMOS sensor with integral memory, paired with an upgraded BIONZ XR processing engine offering up to 8x faster processing than previous-generation Sony bodies, along with significantly reduced rolling shutter distortion. This combination allows the a1 to continuously capture full 50.1MP images at up to 30fps with up to 120 AF/AE calculations per second, an unprecedented pairing of resolution and speed at the time of its release. ISO sensitivity spans a native range of 100-32000, expandable to 50-102400.
Autofocus uses Sony’s Fast Hybrid AF system across all shooting modes for both stills and video, delivering fast, accurate subject acquisition and tracking. In-body 5-axis SteadyShot INSIDE image stabilization is rated for 5.5 stops of effective correction, compensating for five different types of camera shake during handheld shooting, with an additional Active IS mode available specifically for video to deliver smoother, more precisely stabilized footage straight out of camera.
Video capability includes 8K recording at 30p in 10-bit 4:2:0, along with 4K recording at up to 120p in 10-bit 4:2:2, offering approximately 15 stops of dynamic range for extensive post-production flexibility. Handling centers on an OLED Quad-XGA electronic viewfinder with a refresh rate of up to 240fps, delivering a remarkably smooth live view even during high-speed continuous shooting. Connectivity is built for demanding professional workflows, including built-in Wi-Fi (2.4GHz and 5GHz) supporting wireless tethered shooting and remote camera control, a USB Type-C port supporting SuperSpeed USB (10Gbps) for fast tethered data transfer and in-camera charging, a full-size HDMI Type-A port for reliable external recorder connections, and compatibility with an optional wired LAN adapter for 1000BASE-T Ethernet connectivity, wired remote shooting, and FTP file transfer, including approximately 3.5x faster wireless FTP transfer speeds than prior Sony bodies.
Build quality includes dual card slots supporting both CFexpress Type A and SD media, along with a dual-drive mechanical shutter rated for flash sync up to 1/400 second. The a1 uses Sony’s E-mount lens system, giving it access to Sony’s full range of native full-frame and APS-C E-mount lenses, along with third-party options.
