Optical camera system

An optical camera system, comprising, in order from an object side to an image side along an optical axis:

• a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens and a ninth lens all having refractive power,
• wherein the first lens has a convex object side surface;
• wherein the first lens, fourth lens, and the eighth lens all have positive refractive power, and the third lens, the fifth lens, and the ninth lens all have negative refractive power;
• and
• a distance TTL from an object side surface of the first lens to an imaging plane of the optical camera system on the optical axis and a half ImgH of a diagonal length of an effective pixel region of the optical camera system satisfy:
• TTL/ImgH<1.5;
• wherein an effective focal length f1 of the first lens and a total effective focal length f of the optical camera system satisfy:
• 0.7<f1/f≤1.
