In an image pickup apparatus including an image sensor and a zoom lens configured to form an image on the image sensor, the zoom lens includes, in order from an object side to an image side, a first lens unit having a positive refractive power, a second lens unit having a negative refractive power, a third lens unit having a positive refractive power, and a subsequent lens group including one or more lens units. In the zoom lens, during zooming, the first lens unit is stationary, the third lens unit moves along a locus convex towards the object side, and three or more lens units including the third lens unit and the image sensor move. An optical total length of the zoom lens is longer at a telephoto end than at a wide-angle end.
