Your camera’s focus most likely looks for hard contrast vertical lines in your picture then racks the focus through its range and looks for the sharpest transition between those contrast lines. In this picture you can see that all the vertical lines have very high and sharp contrast.
Yes I do live as well the P1 menu is great and simple, but live cameras don’t need as much controls on the operators side as it’s mostly via CCU. The grassvalley are the worst, it’s kind of impressive how bad they are.
I’m a camera operator. I work with different cameras on every movie set. The Sony cameras are known to have the worst menu system of all. It’s extremely dense, organized in a manner that makes no sense when on set (the frequently used options are buried in sub menus) and the navigation is painful with a crappy clicky roller. Even the sales rep for Sony openly apologized for the menus. This is unacceptable for a $52,000.00 camera. On the opposite side, there’s ARRI Alexa which has the simplest menu of all. Just a few pages of organized items with simple names. And a lot of common options accessible on the main screen.
True.
