Patent ID: 8649673

Claim:
An image pickup apparatus including a zoom lens barrel that moves between a collapsed position and a shooting position in an optical axis direction to thereby change a photographing magnification, comprising: a lens group movably disposed along a first optical axis; a reflective optical element configured to be movable along a second optical axis extending in a direction intersecting with the first optical axis, and to bend a light beam incident from said lens group in a direction of the second optical axis, to thereby guide the light beam to an image-forming plane when said lens group has moved to the shooting position along the first optical axis, and move to a retracted position along the second optical axis to form a space for accommodating said lens group when said lens group has moved to the collapsed position along the first optical axis; a first actuator for actuating said reflective optical element in the direction of the second optical axis; and a non-reflective optical element disposed between said reflective optical element and the image-forming plane, wherein said non-reflective optical element can be moved in the direction of the second optical axis together with a second actuator for actuating said non-reflective optical element, the second actuator being disposed, at least when said lens group is in the collapsed position, at a location where the second actuator overlaps said reflective optical element when viewed from the direction of the first optical axis.
