Abstract

PURPOSE: To enable correct focus and exposure to be obtained with respect to a certain field portion at the specified distance within a flash coupling range by providing the condition circuit including a switch which changes over from the 1st state to the 2nd state when flash potographing is set.
CONSTITUTION: When a changeover 15 material is set in the position matching the mark 16 in order to make flash photographing, a switch SW1 is closed and an inverter 19 outputs a high level signal as a condition signal. When in this state the high level signal is unobtainable in any of terminals Z1, Z2, Z3, i.e., when the subject is in a remote distance zone, or when the subject is so dark that a distance measuring device 14 is unable to detect the subject distance, transistors Tr1, Tr2 are held in a cutoff state and only the transistor Tr3 conducts to energize an electromagnet 8, by which the leftward movement of a lens extension member 3 is stopped and in this case it turns out that the focus of the photographic lens L mathes the second middle distance zone.
