Advanced 20.3M APS-C CMOS Sensor The 20.3MP APS-C CMOS sensor with Phase detection AF delivers high-quality images & lifelike colors with the highest resolution in its class. The sensor collects the most light so you can create beautiful images without noise, even in low-lit situations. Advanced Hybrid AF System Phase detection AF (autofocus) determines the distance of your subject, while contrast AF fine-tunes the focus for maximum contrast. The hybrid AF system combines both into a single sensor which means that you can shoot accurate & sharply detailed images faster. 8.6fps Continuous Shooting Continuously shoot at an ultra-fast rate of 8.6 frames per second. The advanced autofocus system brings crystal clarity to fast-moving subjects & the short shutter release lag helps you capture the fleeting moment before the subject moves out of frame.
