Inside the a7R III is a 42.4-megapixel back-illuminated full-frame Exmore R CMOS sensor. Despite its high megapixel count, the a7R III is fast with a continuous shooting speed of up to 10fps with full AF/AE tracking — this is twice as fast as the 5fps offered by the a7R II.Using either the mechanical shutter or the completely silent shooting mode, you can capture a burst of up to 76 JPEG/RAW photos and 28 uncompressed RAW files. In live view, you can shoot at 8fps with minimal viewfinder/LCD lag. The updated BIONZ X processing engine can also process images 1.8 times faster than the a7R II. While a batch of photos is being written to the memory card, many of the camera’s key features are still usable — things like the Function and Menu buttons as well as image playback and organization. Compared to the a7R II, the new a7R III also features new technologies — a gapless on-chip lens design and anti-reflective sensor coating — to achieve better low-light performance and wider dynamic
