The Sony a7R III improves on existing features and includes a slew of new ones, all of which make it a worthy successor. Updated image processor The new BIONZ X makes the a7R III operate faster, bumps up the dynamic range up to 15-stops, and makes it produce more detailed images with better performance in low light. Bigger battery Like the Sony a9, the a7R III uses the new NP-FZ100 battery, which has a capacity of 2,280mAH. The NP-FW50 that previous models used only had a capacity of 1,020mAH, which means that the a7R III with its new battery should theoretically last twice as long. We will be testing out all these new features in the real world for our full review of the Sony a7R III, so be sure to stay tuned for that.
