Endoscope system having two endoscopes with different viewing angles

An endoscope system, comprising:

• a first endoscope that includes a first observation optical system with a first viewing angle;
• a second endoscope that includes a second observation optical system with a second viewing angle wider than the first viewing angle, a second distance from a second distal end face of an insertion portion of the second endoscope to a minimum focal point of the second observation optical system being shorter than a first distance from a first distal end face of a distal end portion of the first endoscope to a minimum focal point of the first observation optical system;
• a processor configured to process image signals from the first endoscope and the second endoscope, the first endoscope and the second endoscope being connectable to the processor through a connector portion;
• and
• a display device configured to display an observation image based on the image signals processed by the processor, wherein
• the first endoscope includes the first observation optical system with the first viewing angle and a fixed focal point, and
• the second endoscope includes the second observation optical system with the second viewing angle wider than the first viewing angle and a fixed focal point.
