24.3MP Exmor APS HD CMOS Sensor and BIONZ X Image Processor The 24.3MP APS-C-sized Exmor APS HD CMOS sensor and BIONZ X image processor work together to produce high resolution, well-detailed imagery with minimal noise and notable low-light quality and sensitivity to ISO 25600. The sensor utilizes a gapless on-chip lens design, which fills the gaps between neighboring pixels with optimized lenses that match the angle of incidence to increase light gathering ability and produce edge-to-edge sharpness and quality. The processor also contributes to providing a wealth of speed throughout the camera system, including Fast Hybrid AF, a top continuous shooting rate of 11 fps, and full HD 1080i/p video recording in multiple frame rates. Fast Hybrid AF System The Fast Hybrid AF system utilizes both a 179-point phase-detection system and 25-point contrast-detection system to achieve precise focus in as little as 0.06 sec. Utilizing a Spatial Object Detection algorithm, this fast focusing system first employs the phase-detection AF points to quickly bring the subject into focus and then uses the contrast-detection AF points, with wide AF coverage, to fine-tune the sharpness for ensured accuracy. Beyond supporting single shot modes, this system also provides AF tracking when shooting up to 11 fps in continuous high mode and functions seamlessly when recording full HD movies. For further refinement, a series of distinct AF modes can be selected from depending on the subject. Eye AF is a detail-oriented focusing function that can prioritize a subject's pupil and dedicate focusing performance on that for sharply-rendered portraits; Lock-on AF is a dedicated focusing method for use with moving subjects and adjusts the target frame size as the subject moves throughout the image frame; AF area settings allow you to prioritize specific regions within the frame for increased accuracy; and AF-A (Automatic AF), AF-S (Single-shot AF), AF-C (Continuous AF), DMF (Direct Manual Focus), and Manual Focus modes can also be chosen.
