摘要:PURPOSE:To prevent out-of-focus in the stage of photographing at shortdistances by generating a short distance signal and operating a flash device to increasethe luminance of an object and by stopping down the aperture to increase the depth offield in the stage of photographing at short distances. CONSTITUTION:When theluminance of a subject is brightness of about a medium degree, a control circuit 43operates in accordance with the output of a photometric circuit 44 and the 2nd switch 41goes on. When the object distance is a prescribed value or below (for example, <=1m), alens limiting plate 11 moves upward and contact pieces 21a and 21b are brought intocontact with each other by a projecting part 11, by which the 1st switch 21 is turned on.Then, a magnet 24 is excited and a lever 28 is turned right to pop up a strope 31.Thereafter, the photographing by a flashmatic system is executed, and an aperture 4 isstopped down according to the distances of the object, whereby the sufficient depth offield is obtained.
