45.7 MP Stacked BSI CMOS Sensor
The core of the Z 9 is the newly developed FX-format 45.7MP BSI stacked CMOS sensor. Its stacked design offers fast readout speeds and helps to reduce rolling shutter, and the BSI design contributes to impressive clarity and minimal noise when working at higher sensitivities. At 45.7MP, it’s also a high-resolution chip that benefits landscape, portraiture, and other detail-oriented genres, as well as enables recording video at resolutions up to 8K. The full-frame BSI design is known for exquisite color and detail rendering, too, and this sensor offers a native ISO 64-25600 range, that can be expanded to ISO 32-102400.
EXPEED 7 Image Processor
Complementing the sensor is an advanced processing engine, the EXPEED 7, which offers speeds approximately 10x faster than a Z 7II. This engine works in conjunction with the stacked sensor design to realize impressively fast AF speeds, burst shooting rates, a high buffer capacity, fluid video performance, and quick all-around handling.
- Top continuous shooting speeds of 20 fps when shooting in raw, 30 fps when shooting in JPEG, and an impressive 120 fps shooting rate when recording 11MP stills, with all rates supporting full AF/AE performance.
- Able to buffer over 1000 raw images in a burst, meaning raw image sequences can be recorded for approximately 50 seconds continuously.
- Electronic shutter affords a top shutter speed of 1/32,000 sec for working in the brightest conditions with wider apertures.
- Stacked sensor design reduces rolling shutter distortion so fast-moving subjects, like a golf club, tennis racket, or baseball bat, do not appear distorted when working with shutter speeds up to 1/32,000 sec.
- AF calculations are done at a 120 fps rate to keep up with fast continuous shooting speeds.
- New High Efficiency RAW file format maintains image quality akin to uncompressed raw files but with file sizes approximately 30% smaller for faster reading/writing to the memory card.
