Abstract
A photographing apparatus including an in-focus position detector for detecting an in-focus position of a focusing lens to focus an image of a subject on an image pickup surface, a driving controller for controlling the driving of the focusing lens, a reflective member that opens and closes on a path of a light that is irradiated onto the image pickup surface, and an optical measuring unit measuring a brightness of the subject image that is reflected by the reflective member in a closed state when a preliminary light emission operation is performed with respect to the subject before performing a main exposure operation. In the preliminary light emission, the driving controller drives the focusing lens to a position nearer the subject or a position nearer the image pickup surface, rather than to the in-focus position of the focusing lens detected by the in-focus position detector.
