A First Assistant Camera is responsible for adjusting or adapting the focus to accommodate changes to the focal length (distance of the camera lens from the subject) when characters are moving closer or further away from the camera. The First Assistant Camera (AC) is usually requested by the Director of Photography or the Camera Operator and works on a freelance basis. Working hours are long and demanding in this role.

First Assistant Camera Job

Previously known as the Focus Puller, the First Assistant Camera has a highly skilled position and is responsible for consistently focusing and refocusing the camera lens as actors are moving within the frame of the shot. First ACs don’t use the lens to guide their adjustments to the camera but instead pull focus according to various complex marks that are placed on the set during the Director’s rehearsal time with the cast. These marks are placed on the floor, props, and in various locations. First Assistant Cameras utilize instinct and their experience, which improves over time, to judge focal lengths. They won’t know just how sharp the focus was until the rushes are screened, and, since re-shooting is expensive, First ACs must be extremely reliable in the instinct and experience to ensure the shoot is effective the first time.

First Assistant Camera Responsibilities

First Assistant Cameras have several responsibilities in relation to focus including maintaining camera equipment such as lenses, filters and matte boxes and properly assembling the camera for upcoming shots. As such, they often arrive on set or in the studio before much of the production team to ensure that the camera and all lenses required are prepared and ready before the day’s shoot is set to begin.
