HOW DO YOU FOCUS A LENS THAT’S IN THE AIR?
Since all of the most popular micro-four-thirds lenses already focus electronically, it has integrated an autofocusing system that works just like any modern smartphone. You just tap the area that you want to focus on in the app and it will do the rest. You’ll also be able to adjust the focus manually using the app, but there’s one other way of focusing that professional filmmakers will love. In addition to that manufacturers have also come out with a wireless follow focus system that will work directly with the remote so you can precisely pull focus from the ground. The remote follow focus will also have a button interface so you can set focus points to create automated focus moves.
