More Information
Summary:An imaging lens system is provided. The imaging lens system includes a first lens having refractive power; a second lens having positive refractive power and having a concave image-side surface; a third lens having refractive power; a fourth lens having positive refractive power and having a concave image-side surface; a fifth lens having a concave object-side surface; a sixth lens having a concave image-side surface; a seventh lens having a convex object-side surface; and an eighth lens having refractive power, wherein the first to eighth lenses are sequentially arranged from an object-side to an imaging side, and the imaging lens system satisfies the following conditional expression: 0.15 < BFL/TTL, where BFL is a distance from an image-side surface of the eighth lens to an imaging plane, and TTL is a distance from an object-side surface of the first lens to the imaging plane. An electronic device is also provided.
