Lens assembly and electronic device including the same

An electronic device comprising:

• a processor;
• and
• a lens assembly, wherein the lens assembly comprises:
• an image sensor configured to capture an image of an object;
• a first lens group disposed closest to an object side in three lens groups sequentially arranged from the object side toward the image sensor along an optical axis direction, the first lens group including multiple lenses and having negative power;
• a second lens group disposed to be moveable forward/backward along the optical axis direction between the image sensor and the first lens group, the second lens group having positive power;
• and
• a third lens group disposed to be moveable forward/backward along the optical axis direction between the image sensor and the second lens group, the third lens group including multiple lenses and having negative power, wherein:
• the second lens group and/or the third lens group is configured to move toward the object side in a zooming operation so as to increase a focal length of the lens assembly, and
• the second lens group comprises a (2-1)st lens having positive power, a (2-2)nd lens having positive power, a (2-3)rd lens having negative power, and a (2-4)th lens having positive power, which are sequentially arranged from the object side toward the image sensor,
• at least one lens in the first lens group and the second lens group has a non-circular shape, and an edge of the at least one lens in the first lens group and the second lens group is treated with black painting, by digging, or with carbonation, and
• the lens assembly is configured to satisfy the following [Condition formulas 1 and 2]:
• 0.1≤G2air/tG2≤0.3 [Condition formula 1]
• 0.85≤fG2P/fG2≤1.25 [Condition formula 2]
• wherein “G2_air” is an air gap between the (2-2)nd lens and the (2-3)rd lens along the optical axis direction, and “tG2” is a distance between an object-side surface of a lens closest to the object in the second lens group, and an image sensor-side surface of a lens closest to the image sensor along the optical axis direction in the second lens group, and
• wherein “f_G2P” is a focal length of the (2-4)th lens closest to the image sensor in the second lens group, and “f_G2” is an entire focal length of the second lens group,
• wherein the lens group has a focal length between 11.2 mm and 11.6 mm and a field of view from between 20 degrees and 28.3 degrees when configured for wide angle, and a focal length between 24.9 mm and 27.5 mm and a field of view between 11.6 degrees and 16.5 degrees when configured for telephoto.
