The invention relates to the field of optical lenses and discloses a camera shooting optical lens. The camera shooting optical lens comprises eight lenses in total, wherein the eight lenses are sequentially a first lens with positive refractive power, a second lens with negative refractive power, a third lens with negative refractive power, a fourth lens, a fifth lens with positive refractive power, a sixth lens with negative refractive power, a seventh lens with positive refractive power and an eighth lens with negative refractive power from the object side to the image side, the total optical length of the camera shooting optical lens is TTL, the focal length of the camera shooting optical lens is f, the focal length of the second lens is f2, the central curvature radius of the object side surface of the seventh lens is R13, the central curvature radius of the image side surface of the seventh lens is R14, and the following relational expressions are satisfied, 0.95 </= f/TTL, -4.50</= f2/f </=-2.00, -0.90 </= (R13+R14)/(R13-R14) </=-0.25. The camera shooting optical lens provided by the invention has good optical performance and further meets design requirements of long focal length and ultra-thinness.
