This video will hopefully help you understand how and when video autofocus should be used. It is such an amazing tool when used correctly! The title is no joke! I have been obsessed with video autofocus since the Canon 1DX MKII truly changed my mind about its usability professionally. My 3 part Autofocus series took two months to make and almost sent me mad. My 2-hour long epic Sony FX9 review, which is where some of the footage in this video has come from can be seen here.
