するビデオシステム。 A video system that includes a video camera that converts a subject image into an electrical signal and outputs it, and a video recorder that records the electrical signal output from the video camera on a recording medium, the video system having a photographic lens attached to the subject. an automatic focus adjustment device that automatically focuses the video recorder; a first switch that sets the video recorder to a recording standby state in which the recording head and the recording medium move relative to each other; a second switch that operates the automatic focus adjustment device by a subsequent operation; a third switch operated by a trigger member; and a focus adjustment of the photographic lens outputted from the automatic focus adjustment device. A recorder trigger circuit receives a signal indicating completion and an operation signal of the third switch, and the recorder trigger circuit receives the operation signal of the third switch after the first switch is turned on. A video system characterized in that the video recorder starts recording under the conditions that input is received and focus adjustment of the photographic lens is completed.
