Sony's 1-inch bridge camera with stacked sensor — 4K and 960fps slow-motion at 24-200mm equiv.
The Sony Cyber-shot RX10 Mark II was released in 2015 as a 1-inch sensor bridge camera with a fixed Carl Zeiss Vario-Sonnar T* 24-200mm f/2.8 constant-aperture zoom and stacked BSI CMOS for high-speed video. 20.2MP. 4K/30fps. At approximately 755g body only. Fixed non-interchangeable zoom.
20.2MP 1-inch (25.4mm) Exmor RS BSI stacked CMOS. Fixed Carl Zeiss Vario-Sonnar T* 24-200mm f/2.8 constant aperture (8.3× zoom). 4K/30fps (XAVC S); 1080p/60fps; super-slow motion up to 960fps at reduced resolution. 14fps burst. Approximately 755g body only. Weather-sealed. Fixed zoom — no interchangeable mount.
The RX10 II's constant f/2.8 across 24-200mm is the primary capability: f/2.8 at 200mm enables shallow telephoto depth of field and low-light performance that variable-aperture superzooms at f/5.6-6.3 cannot match. The stacked BSI CMOS enables 960fps super-slow-motion, enabled by the fast sensor readout that stacking provides. The 4K and high-speed video were headline features versus the RX10 original (which lacked 4K).
On the used market the Sony Cyber-shot RX10 Mark II is available at 1-inch bridge camera pricing. Condition checks: zoom mechanism smoothness, lens element for marks, weather sealing. Fixed Zeiss 24-200mm f/2.8 constant zoom — no interchangeable mount.
