Abstract
Provided are an imaging lens system, a camera module and an electronic device. The imaging lens system, from an object side to an imaging plane, sequentially includes: a first lens with a negative focal power, a second lens with a positive focal power, a third lens with a positive focal power and a fourth lens with a negative focal power. An object side surface of the first lens includes a paraxial region and a peripheral region. In the object side surface of the first lens, at least one inflection point is defined between the paraxial region and the peripheral region, and the paraxial region is concave relative to the at least one inflection point. An image side surface of the third lens is convex. A paraxial region of an image side surface of the fourth lens is concave.
