Embodiment 1
[0071] Such as Figure 1 to Figure 42 As shown, the camera lens includes a front lens group and a rear lens group in sequence from the subject side to the imaging side; the front lens group includes a first lens, a second lens and a third lens with positive refractive power; the rear lens group The group includes a fourth lens whose surface close to the imaging side is convex and a fifth lens whose surface close to the imaging side is convex; wherein, the surface of the first lens near the subject side of the camera lens in the macro configuration is to the imaging lens The on-axis distance TTL1 of the surface and the effective focal length f of the camera lens satisfy: TTL1 / f<1.3; the effective focal length f2 of the second lens and the effective focal length f4 of the fourth lens satisfy: 0<f2 / f4<1.0.
[0072] Preferably, 0.3
[0073] By reasonably distributing the power and surface shape of each lens in the front group lens group and the rear group lens group, i...
Embodiment 2
[0092] Such as Figure 1 to Figure 42 As shown, the camera lens includes a front lens group and a rear lens group in sequence from the subject side to the imaging side; the front lens group includes a first lens, a second lens and a third lens with positive refractive power; the rear lens group The group includes a fourth lens whose surface near the imaging side is a convex surface and a fifth lens whose surface near the imaging side is a convex surface; wherein, the effective focal length f2 of the second lens and the effective focal length f4 of the fourth lens satisfy: 0<f2 / f4<1.0; the magnification M of the camera lens satisfies: 0≤M<0.1.
[0093] Preferably, 0.3
[0094] By reasonably distributing the power and surface shape of each lens in the front group lens group and the rear group lens group, it can effectively avoid lens sensitivity problems caused by excessive concentration of power, and can also effectively balance spherical aberration, Chromatic abe...
