The invention relates to the field of optical lenses, and discloses a photographic optical lens. The photographic optical lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which are arranged from the object side to the image side in turn. The second lens has negative refractive power, the third lens has negative refractive power and the following relational expressions are met: 1.1<=f1/f<=5; 1.7<=n4<=2.2; 0.02<=d7/TTL<=0.08. The photographic optical lens can acquire high imaging performance and can acquire low TTL.
