Optical lens assembly and electronic device including the same

An optical lens assembly consisting of:

• a first lens;
• a second lens;
• a third lens comprising an image side surface that is concave toward an image side of an optical axis in a region adjacent to the optical axis and has at least one inflection point;
• a visible light cut-off filter;
• and
• an aperture stop disposed on an object side surface of the first lens,
• wherein:
• the aperture stop, the first lens, the second lens, the third lens, and the visible light cut-off filter are sequentially arranged from an object side to the image side of the optical axis, the object side facing an object for image capture and the image side facing an image plane of an image sensor, the third lens is arranged closest to the image plane, and
• the optical lens assembly satisfies following condition:
• 0.49≤T13/OAL≤0.7,
