Full-Frame Stacked Integral-Memory CMOS Sensor

The 24.2-megapixelfull-frame high-speed stacked image sensor stores data in integral memory for lightning-fast readout. The CMOS sensor and enhanced BIONZ X image-processing engine together bring you true digital freedom.

Speed meets artificial intelligence

Real-time Tracking and Real-time Eye AF are both designed for fast, precise and intelligent tracking of your subject, using AI-based algorithms and processing an enormous amount of data in real time.

AI-based Real-time Tracking

After the subject is specified, precise focus is maintained while the shutter button is half-pressed. Position changes are accurately tracked, providing framing flexibility as you concentrate on getting the best shot.

Reliable even in low light

Advanced AF algorithms contribute to AF precision at light levels as low as EV-3. The Focus Priority in Aperture Drive option is for more accurate focusing in dim lighting and when the aperture is stopped down.

Improved Focus Frame Usability

Even with the shutter button half-pressed, the focus area can now be moved with the multi-selector to any location. Conveniently, the focus frame color can be set to red or white to suit the scene.
