Patent ID: 11137586

Abstract:
A zoom lens consists of, in order from the object side to the image side, a first lens unit having a positive refractive power and configured not to be moved for zooming, a second lens unit having a negative refractive power and configured to be moved for zooming, and a rear lens group including at least one lens unit. The first lens unit includes at least six lenses, a lens closest to the object side included in the first lens unit is a negative lens, and the zoom lens satisfies conditional expressions: −1.65<f1n/f1<−1.10; 37<ν1n<48; and 87<νpave<100, where f1n is a focal length of the negative lens, ν1n is an Abbe number of the negative lens with respect to d-line, f1 is a focal length of the first lens unit, and νpave is an average of Abbe numbers of positive lenses included in the first lens unit with respect to d-line.
