Abstract
Official abstract text for this publication.
An image pickup apparatus includes a zoom lens and an image pickup element. The zoom lens includes a first positive lens unit, a first negative lens unit, a stop, and a second positive lens unit. For zooming, the first positive lens unit is stationary, the first negative lens unit moves, and the second positive lens unit moves. A position at a telephoto end of the first negative lens unit is on the image side of a position at the wide angle end. A position at a telephoto end of the second positive lens unit is on the object side of a position at the wide angle end. For focusing, the first positive lens unit is stationary. A first positive lens unit object-side system has a negative refractive power. A first positive lens unit image-side system has a positive refractive power. The image pickup apparatus satisfies predetermined conditional expressions.
