A microscope system comprises an objective, an image pickup device, a diameter-variable field stop disposed in a conjugate position with the focal plane of the objective, a magnification modifying device disposed in an optical path between the objective and the image pickup device, for modifying the magnification of the image pickup device and a control unit for controlling in such a way as to maintain a state where a field stop diameter is always larger than a field diameter. |
