Lens assembly and electronic device comprising same

An electronic device comprising:

• a lens assembly comprising at least seven lenses sequentially arranged along an optical axis from an object side to an image sensor side, the at least seven lenses comprising a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens arranged the object side to the image sensor side in that order;
• an image sensor aligned with the at least seven lenses on the optical axis and configured to receive light focused or guided by the at least seven lenses;
• and
• a processor configured to obtain an image based on the light received by the image sensor,
• wherein the first lens is a plastic lens, and the first lens comprises an object-side surface that is convex and has a positive refractive power,
• wherein the second lens has a negative refractive power,
• wherein the third lens comprises an object-side surface having a maximum absolute value of a sweep angle that is less than or equal to 10 degrees,
• wherein the fifth lens comprises an object-side surface and an image sensor-side surface, and at least one of the object-side surface or the image sensor-side surface of the fifth lens has a maximum absolute value of a sweep angle that is greater than or equal to 45 degrees,
• wherein the sixth lens comprises an image sensor-side surface that is convex and an object-side surface, and at least one of the object-side surface or the image sensor-side surface of the sixth lens has a maximum absolute value of a sweep angle that is greater than or equal to 45 degrees,
• wherein the seventh lens has a negative refractive power, and the seventh lens comprises an object-side surface that is aspheric and convex and has at least one inflection point, and an image sensor-side surface that is aspheric and concave and has at least one inflection point, and
• wherein at least one of surfaces of the at least seven lenses has a visible light reflectance that is less than or equal to 0.3%.
