Animal Eye AF with running dog

During the morning photo walk I surprisingly had the opportunity to take pictures of dogs on the beach in full run. For possible water birds I had the FE400 with 1.4x converter on the Sony A9. Even under these conditions the AF worked very well. And the closer the dog came the more I noticed how the autofocus had to work. The engine noise became louder and louder. The result is impressive. The individual photos can be found here.
