A microscope provided with a photographing device which has a structure for always projecting an optimum image onto an image pickup device, a structure for correcting image data obtained from the image pickup device to eliminate the influences of the unevenness of the brightness distribution of the projected image and the unevenness of the characteristics of each picture element forming the image pickup device, a structure for bringing a focusing stage to an in-focus position adapted to an objective selected to be used on the basis of the corrected image data and a structure for making an out-focus indication when the focusing stage is brought to a predetermined upper limit position or lower limit position, to make high precision, quick automatic focusing possible.
