Zoom lens and image capture apparatus having the same

A zoom lens comprising:

• a first lens unit having a negative refractive power;
• a second lens unit having a positive refractive power;
• and
• a rear group including two or more lens units, wherein
• the first lens unit, the second lens unit, and the rear group are disposed in order from an object side toward an image side,
• in zooming, the first lens unit is arranged to move, and each interval between adjacent lens units changes,
• the rear group includes all lens units arranged on the image side of the second lens unit in the zoom lens,
• the second lens unit comprises a plurality of cemented lenses,
• a refractive index of a negative lens A disposed closest to an object, among negative lenses included in the first lens unit, is greater than or equal to 1.89, and
• the following inequalities are satisfied:
