- Upgraded 2.5GBASE-T Wired Ethernet: Heavy-duty 2.5Gbps LAN interface provides rapid, secure FTP press-room transfers for tethered field environments.
- Dual Multi-Slot Combo Trays: Both physical memory card bays independently accept either high-speed standard SD UHS-II cards or ultra-fast CFexpress Type A media.
Product Overview
The Sony Alpha 1 Mark II (Body Only) stands as a monument to modern camera engineering, removing the historical barrier between hyper-detailed commercial resolution and extreme action speed. At its foundational core is the acclaimed 50.1-megapixel stacked back-illuminated sensor. By processing image data through dual BIONZ XR engines and a hardware AI unit, the camera operates at a velocity that allows photographers to lock onto moving targets at 30 frames per second with a completely blackout-free electronic viewfinder. This design completely changes the pace for wildlife trackers, sports photojournalists, and runway creators handling spontaneous, rapid motion.
