Abstract:
A zoom lens includes in order from an object 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 first lens component in the predetermined lens unit moves perpendicularly with respect to an optical axis and is fixed at the time of zooming, and a second lens component is disposed, leaving an air space on an image side of the first lens component, and a sign of a refractive power of the second lens component differs from a sign of a refractive power of the first lens component, and the following conditional expression (1) is satisfied. 3.4≤|f1/f3|≤9 (1)
