Proving that speed resolution and video capabilities can all coexist the Sony a7R IIIA is a versatile high performance camera characterized by not only its resolution but by its multimedia versatility. Featuring a back illuminated design the full frame 42.4 megapixel Exmor R CMOS sensor works with the BIONZ X image processor to offer high resolution stills and video while minimizing noise and improving speed. This sensor structure works with gapless on chip lens design and an anti reflection coating as well as eliminating the optical low pass filter to improve light collection and enhance detail. Also the copper wiring layer dramatically improves data transmission speed for creating 14 bit high resolution 42.4 megapixel stills with a native sensitivity range from ISO 100 32000 which can be further expanded to ISO 50 102400. Also it enables internal UHD 4K video recording with a wide dynamic range using the full width of the full frame sensor. The BIONZ X processor also works in conjunction with a high speed front end LSI to realize faster processing times along with the ability to capture an impressive 15 stop dynamic range at low sensitivity values. The sensor and processor combination also avails fast continuous shooting at up to 10 fps at full resolution for up to 76 consecutive frames and with full time AF/AE when working with either a mechanical shutter or an electronic shutter. If shooting in live view mode a continuous shooting rate of up to 8 fps is also possible.
