🔑 增強重點摘要
- •Sony is developing a 16MP full-frame partially stacked CMOS sensor with 240fps readout speed, doubling the 120fps of the Sony A7V, enabling near-5K oversampled 4K at 240fps[1][2][3][7]
- •Sensor features 7.2μm pixels for improved low-light performance, full-pixel dual-point PDAF at 120fps, active IBIS with minimal crop, and built-in DCG-HDR from Sony mobile sensors[1][2][3]
- •Targeted for FX3 II (Q2 2026) and A7S IV (late 2026), replacing earlier 33MP sensor rumors for FX3 II which were deemed likely fake[1][3]
- •Partially stacked design offers faster readout than standard BSI CMOS but lower cost and power than fully stacked, reducing rolling shutter and heat for high-frame-rate video[1][2][3]
- •Provides advantages like superior 4K sharpness from 5K oversampling, enhanced dynamic range, and run-and-gun stabilization without gimbals[1][3]

*Note: Competitor benchmarks from 2025 reviews; Sony rumors unconfirmed[1][3][5]
🛠️ 技術深入
- Sensor Type: Partially stacked CMOS (Exmor RS-like), full-frame 16MP with ~7.2μm pixel size for better low-light vs higher-res sensors[1][3]
- Readout: 240fps full-frame theoretical max (sensor-level), 120fps with PDAF; reduces rolling shutter for high-speed video[1][2][3][7]
- Video: Near-5K raw readout oversampled to 4K 240fps; supports active stabilization, DCG-HDR (Dual Conversion Gain) for extended dynamic range in stills/video[1][2][3]
- AF/Stab: Full-pixel 2-point PDAF at 120fps; IBIS with low crop factor for handheld high-fps shooting[1][3][7]
- Advantages: Lower heat/power than fully stacked, efficient for 4K/5K without 8K overhead; from mobile sensor tech adaptation[2][3]
🔮 前景展望AI analysis grounded in cited sources
This sensor could enable affordable pro-grade 4K 240fps/HDR video in compact bodies like FX3 II, challenging Canon/Nikon in hybrid cinema market by prioritizing speed/low-light over resolution. May shift industry toward partially stacked for cost-effective high-fps, but paywall risks could frustrate creators[1][3]
