We Updated Our Sony A9 Review After Testing Firmware Update 5.0

Taking a page out of Fujifilm's books, Sony released a major firmware update for their flagship A9 last week that brings the camera's firmware to version 5. 0. This new firmware update leverages the company's latest developments into Artificial Intelligence, machine learning, and object recognition and adds Real-Time Tracking (first seen in the Sony A6400) along with automatic Eye Autofocus to improve upon the already unparalleled performance of the Sony A9.
