the physical location within the lens assembly where an image is inverted.
the practice of adjusting the camera's lens settings to make the footage of the subject clear and not blurry.

the strength of a video/audio signal.
when the camera is actively rolling.
component of a lens that is composed of blades expand and contract, thus adjusting the aperture size.

three-legged stand often used to support a camera
the assembly at the top of the pedestal column to which the camera attaches.
variable focal length lens
also known as a "zoom lens"; camera lens in which the optical center can vary its position within the lens assembly.
a live preview of what the camera sees so that the camera operator can indicate the boundaries of the camera's point of view.
also known as "zoom out (ZO)"; act of rotating the zoom lens so the subject looks like it's away from the camera.

zoom in (ZI)
act of rotating the zoom lens so the subject appears to be moving closer to the camera.
piece of glass within the lens assembly that moves forward and back, magnifying and shrinking the image accordingly.
camera lens assembly capable of magnifying an image merely by twisting one of the rings outside of the lens housing.
