An endoscope comprising:

• an objective optical unit comprising:
• a lens;
• a lens frame holding the lens;
• and
• an actuator connected to the lens frame, the actuator configured to move the lens frame in a direction of an optical axis, the actuator including a plurality of magnets and a coil;
• and
• a plurality of internal components made of magnetic material and arranged around the objective optical unit, the plurality of internal components being other than portions comprising the actuator, wherein
• each of the plurality of internal components are fixed relative to the lens frame.
