Abstract
A zoom lens includes, in order from an object side to an image side, a first lens unit having positive refractive power that does not move during zooming, an intermediate group that has at least two lens units moving during zooming, a lens unit having positive refractive power that moves during zooming, and a final lens unit having positive refractive power that does not move during zooming. Each distance between adjacent lens units changes during zooming. The intermediate group includes at least one lens unit having negative refractive power and including at least three lenses. Of the at least one lens unit having negative refractive power, a lens unit V disposed closest to an object includes at least one positive lens and at least one negative lens, and a lens disposed closest to the object in the lens unit V is a negative lens. A predetermined condition is satisfied.
