Abstract:
Provided is a zoom lens including, in order from an object side to an image side: a first lens unit having a negative refractive power; a second lens unit having a positive refractive power; a third lens unit having a negative refractive power; a fourth lens unit having a positive refractive power; and a rear lens group including at least one lens unit, the first lens unit, the second lens unit, the third lens unit, the fourth lens unit, and the rear lens group having an interval between each pair of adjacent lens units changed for zooming. The third lens unit is configured to move for focusing, and at least a part of the fourth lens unit forms a lens system IS, which is configured to move in a direction including a component of a direction perpendicular to an optical axis for image stabilization.

Claim (Index 16):
An image pickup apparatus, comprising:\n a zoom lens; and an image pickup element, which is configured to receive an image formed by the zoom lens,\n the zoom lens comprising, in order from an object side to an image side:\n a first lens unit having a negative refractive power; \n a second lens unit having a positive refractive power; \n a third lens unit having a negative refractive power; \n a fourth lens unit having a positive refractive power; and \n a rear lens group including at least one lens unit, \n \n the first lens unit, the second lens unit, the third lens unit, the fourth lens unit, and the rear lens group having an interval between each pair of adjacent lens units changed for zooming, \n wherein at least the third lens unit is configured to move for focusing, and wherein at least a part of the fourth lens unit is a lens system IS, which is configured to move in a direction including a component of a direction perpendicular to an optical axis for image stabilization.
