[0061] In this embodiment, the optical zoom lens 100' is basically the same as the optical zoom lens 100 in the first embodiment, the difference is that the third lens group 30' is composed of a seventh lens 31' and an eighth lens 32', the The four-lens group 40' is composed of a ninth lens 33', a tenth lens 41' and an eleventh lens 42'. Wherein, the seventh lens 31' and the ninth lens 33' are aspherical lenses.
[0062] Specifically, the optical zoom lens 100' of this embodiment satisfies the conditions listed in Table 4, Table 5 and Table 6.
