摘要:
An image pickup apparatus includes a lens barrel. The lens barrel is configured to move first and second optical units in an optical axis direction for zooming. The lens barrel includes a linear movement cylinder that includes a key configured to guide the first optical unit, a rotation cylinder that includes an outer circumferential cam and an inner circumferential cam, the rotation cylinder being configured to rotate around an optical axis so as to move the first optical unit in the optical axis direction through the outer circumferential cam and so as to move the second optical unit in the optical axis direction through the inner circumferential cam, and a guide bar held by the linear movement cylinder and configured to guide the second optical unit in the optical axis direction.
