1. A lens assembly comprising:
a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens sequentially arranged along an optical axis from an object side to a sensor side; and
a tunable lens disposed between the second lens and third lens, the tunable lens configured to change power or curvature, and
wherein the lens assembly is configured to:
substantially align a central ray and a marginal ray without a focus deviation when a subject at one distance of 1 m or more is imaged, and
align the central ray and the marginal ray with a focus deviation of about 0.01 mm when a subject at one distance between 30 cm-1 m is imaged, and
wherein the lens assembly has a length between an object-side surface of the furthest lens among the at least four lenses and a sensor surface of an image sensor of about 7.83 mm, a field of view of about 82.34 degrees, and an F-number of 1.90.
