A medical imaging device including at least two cameras. The medical imaging device includes an elongated and narrow distal tip connected to a rigid elongated shaft member, wherein the distal tip includes a front camera and a first side camera. The cameras of the disclosed medical imaging device can be configured to provide variable cameras' magnifications, which in some cases may vary from one camera to another. The cameras of the medical imaging device may be provided with dissimilarity in the cameras' magnification factors. Such dissimilarities are used to show the same object in the same size in a panoramic image captured simultaneously by the multiple cameras, as the multiple cameras have multiple distances to the object.

A stereoscopic-vision endoscope includes an objective optical system, a relay optical system, a first lens unit, a light-beam splitting element, a second lens unit, and an image sensor.
