PROBLEM TO BE SOLVED: To set various kinds of modes without impairing compactification while maintaining magnification changing operation excellently. SOLUTION: A mode setting button 30 is constructed of a single disk type operation member 30a in which an area to be pressed for operation is divided into four quadrauts W1, W2, T1, T2, and four switches SW1, SW2, SW3, SW4 arranged on the backs of the areas W1, W2, T1, T2. The mode setting button 30, by which an ON signal from at least one of the switches SW1, SW2 is detected as a magnification changing signal for a wide angle side while an ON signal from at least one of the switches SW3, SW4 is detected as a magnification changing signal for a telescope side, is used for changing a magnification of an electrically driven type zoom lens 12. The mode setting button 30, by which respective ON/OFF modes of the switches SW1-SW4 are detected as mode setting signals, is used for setting varied kinds of modes. |
