A microscope system comprises an objective(106), an image pickup device(121), a diameter-variable field stop(129) disposed in a conjugate position with the focal plane of the objective(106), a magnification modifying device(113) disposed in an optical path between the objective(106) and the image pickup device(121), for modifying the magnification of the image pickup device(121) and a control unit(132) for controlling in such a way as to maintain a state where a field stop diameter is always larger than a field diameter. |
