Abstract

A camera lens assembly, sequentially from an object side to an image side along an optical axis, includes: a first lens having a negative refractive power; a second lens having a positive refractive power, an object-side surface thereof is a convex surface, and an image-side surface thereof is a concave surface; a third lens having a positive refractive power, and an object-side surface thereof is a convex surface; a fourth lens having a negative refractive power, and an image-side surface thereof is a concave surface; a fifth lens having a positive refractive power; and a sixth lens having a negative refractive power, and at least one of an object-side surface and an image-side surface thereof has an inflection point. Half of a maximal field-of-view HFOV of the camera lens assembly satisfies: HFOV≥55°.
