Shooting optical system, shooting device and mobile terminal

The invention provides a shooting optical system which can excellently correct aberration and realize miniaturization of optical full length in an optical system with a large aperture and a wide angle compared with the prior art. The shooting optical system (10) is provided with: a first lens (L1) having negative refractive power and having a concave surface facing the object side; a second lens (L2) having positive refractive power; a third lens (L3) having negative refractive power; a fourth lens (L4); a fifth lens (L5) having a positive refractive power; and a sixth lens (L6) having negative refractive power and having a concave surface facing the image side. The image-side surface of the sixth lens (L6) has an aspheric shape, and has an extreme value at a position other than the point of intersection with the optical axis (Ax). The shooting optical system (10) satisfies the following conditional expressions: (1) v6 < 35.0... (1), -2.50 < f1/f
