FEATURES Back-illuminated 42.4 MP full-frame sensor The 35 mm full-frame Exmor R CMOS image sensor features 42.4-megapixel14 resolution, back illumination and gapless on-chip lens design for extraordinary sensitivity and dynamic range, anti-reflection (AR) coating on sensor seal glass, and other innovations that unleash the sensor's power to make images look realistic. Further enhanced image processing engine The latest front-end LSI makes data readout from the image sensor approximately two times faster15 and the BIONZ X image processor is now about 1.8 times faster16. Enhanced image processing realizes lower noise and further extended dynamic range across a wide sensitivity range of up to ISO 32000 (standard ISO, expandable to ISO 50-102400 for stills). Moreover, upgraded Detail Reproduction and Area-specific Noise Reduction achieves noise reduction equivalent of approx. one stop in mid-range ISO settings. Also, reproduction of skin color has been dramatically improved, which is advantageous for portrait shooting. The 7R III also supports 14-bit RAW output17 even during silent shooting/continuous shooting. A quantum leap in AF performance An evolved image processing system and 9 camera. AF algorithms optimized for the 7R III improve AF speed, precision, and tracking performance. 399 phase-detection AF points and 425 contrast-detection AF points provide high-density wide-area coverage. Up to approximately two times faster18 AF speed and two times more precise15 AF tracking performance let you capture and maintain focus on nimble wildlife in unpredictable motion. The 7R III also autofocuses reliably down to EV-3 brightness19.
