Sony firmware version 3.0 for Sony A7Riii and Sony a7iii adds animal eye focus. Animal eye focus makes photographing animals like Sean Coonery the BIG Maine Coon Cat easier! By having the eyes in peak focus, the photograph looks outstanding! Below are samples that I captured with the Sony a7Riii with firmware version 3.0 and Sony 24-70GM and Sony 16-35GM lenses. Please share with others and tell me what you think! This is the most significant Sony a7Riii/Sony a7iii firmware update to date!
