One of the most frequently asked questions that I receive about the XDCAM EX cameras is how to adjust back focus. Like all ENG style lenses, the lenses that come with these cameras can sometimes develop back focus issues over time. The cameras all have a method for adjusting this, and luckily the PMW350, PMW320, EX3, EX1R, and EX1 all follow a similar procedure. Watch this video to learn when and how to adjust the back focus on your EX camera.
Note: To access the hidden menu on the EX1 / EX1R, hold the Menu, Scroll Wheel, and Cancel button at the same time. DO NOT adjust anything else in this menu.
