A camera lens is installed in an unmanned aerial vehicle. The camera lens includes, from an object side to an image side, a first lens group, a second lens group, a diaphragm, and a third lens group. The first lens group includes a first lens having a negative refractive power and a second lens having a positive refractive power. The second lens group includes a third lens having a positive refractive power, a fourth lens having a positive refractive power, a fifth lens having a positive or negative refractive power, a sixth lens having a negative refractive power, and a seventh lens having a negative refractive power. The third lens group including an eighth lens having a positive refractive power and a ninth lens having a positive or negative refractive power. The camera lens needs only nine lenses to achieve high-quality imaging for the unmanned aerial vehicle.
