Abstract: The disclosure provides an optical imaging lens group, which sequentially includes from an object side to an image side along an optical axis: a first lens with a negative refractive power; a second lens with a refractive power; a third lens with a refractive power, an image-side surface thereof is a concave surface; a fourth lens with a negative refractive power; a fifth lens with a refractive power; and a sixth lens with a refractive power. Semi-FOV is a half of a maximum field of view of the optical imaging lens group, and Semi-FOV satisfies 45°
