Lens assembly and electronic device comprising same

An electronic device comprising:

• a lens assembly,
• wherein the lens assembly comprises:
• a lens group comprising a plurality of lenses aligned along an optical axis in a direction from an object side toward an image side,
• an image sensor comprising an imaging plane on which an image is formed, and
• a reflective member between the lens group and the image sensor and configured to change a path of light passing through the lens group once or twice,
• wherein a first lens, which is closest to the object side among the plurality of lenses, comprises a synthetic resin and has positive refractive power, and an object side surface of the first lens is convex toward the object side,
• wherein a second lens, which is second closest to the object side among the plurality of lenses, has negative refractive power, an image side surface of the second lens is concave toward the image side, and at least one of an object side surface of the second lens or an image side surface of the second lens is aspherical,
• wherein a lens, which is closest to the image side among the plurality of lenses, has an object side surface that is convex toward the object side, and at least one of the object side surface or an image side surface of the lens is aspherical,
• wherein the lens assembly satisfies:
• 25<L1Abbe−L2Abbe<60, and
• L3Abbe<21, and
• wherein L1 Abbe is an Abbe number of the first lens, L2 Abbe is an Abbe number of the second lens, and L3 Abbe is an Abbe number of the lens closest to the image side among the plurality of lenses.
