Sony's ultimate 1-inch bridge — 24-600mm f/2.4-4 with stacked sensor, 4K, and tracking AF.
The Sony Cyber-shot RX10 Mark IV was released approximately 2017 as the fourth-generation flagship bridge camera in Sony's RX series, featuring a 1-inch sensor and 24-600mm f/2.4-4 Zeiss zoom with phase-detect AF on the 1-inch sensor — enabling fast tracking AF across a wide zoom range. Fixed zoom — no interchangeable mount.
20.1MP 1-inch Exmor RS stacked CMOS sensor. 24-600mm f/2.4-4 Zeiss Vario-Sonnar T* zoom. Phase-detect AF (315 points). 4K/30fps video. 24fps burst with continuous AF tracking. 1080p /960fps super-slow-motion. At approximately 1,095g. Fixed zoom — no interchangeable mount.
The stacked Exmor RS sensor enables the phase-detect AF and the 24fps continuous burst with full AF tracking — capabilities previously absent from 1-inch bridge cameras. The 24fps tracking burst approached interchangeable-lens camera performance for wildlife capture. The 600mm equivalent telephoto end exceeds the RX10 III by providing f/4 at 600mm vs f/4 at 600mm with equivalent optical quality improvements.
On the used market the Sony RX10 Mark IV is the highest-specification compact bridge camera in the RX10 line. Condition checks: fixed zoom mechanism, phase-detect AF tracking speed and accuracy, 4K recording function, battery health (NP-FW50). Fixed zoom — no interchangeable mount.
