Patent ID: 10656398

Abstract:
A zoom lens includes a front-side lens unit, a rear-side lens unit, and an aperture stop. The front-side lens unit includes either one lens unit having a negative refractive power or two lens units having a negative refractive power, and has a negative refractive power as a whole. The rear-side lens unit is disposed on an image side of the front-side lens unit, and has a positive refractive power as a whole at a telephoto end. The rear-side lens unit includes a plurality of lens units, and includes an object-side positive lens unit having a positive refractive power which is disposed nearest to object and the following conditional expressions (1), (2), and (3) are satisfied: 1.2≤|MGB_t|≤6  (1),10≤νdGn_min_p≤27  (2), and−0.03≤TpGn_min_p≤0.014  (3).
