A multi-focal, multi-camera endoscope having a tip section including a first optical assembly for generating a first image of a body cavity； a second optical assembly for generating a second image of a body cavity； at least one illuminator associated with each of the first optical assembly and second optical assembly； and a processing system configured to: zoom the first optical assembly and thereby generate a zoomed first image in place of the first image； and automatically cause a physical display to eliminate a display of the second image and to only display said zoomed first image. To eliminate the display of the second image, the processing system reduces a power supply to the second optical assembly, reduces an illumination intensity of an illuminator associated with the second optical assembly or causes the physical display to power off, darken, or blacken.
