Abstract
A camera has an adjustable focus lens (12) and a mode selector switch (SA/M) for selecting manual or automatic focusing. A lens-position switch (Sp) is closed when the lens is in its normal focusing range and is open when the lens is moved to an at- rest position outside the normal focusing range, the at-rest position constituting the lens starting position for an automatic focusing operation. Closure of the mode selector switch and a further switch (S1F) initiates a sequence including acoustic automatic focusing and exposure, followed by automatic return of the lens to the at-rest position. When the mode-selector switch is opened and the camera is manually focused, closure of another switch (S1T) initiates an exposure; thereafter closure of the mode-selector switch will automatically return the lens to the at-rest position and open the lens switch (Sp) connected in series with the mode-selector switch. <IMAGE>
