Abstract
An optical zoom lens module includes, in this order from the object side to the image side thereof, a first lens group of positive refraction power, a second lens group of negative refraction power, a third lens group of positive refraction power, and a fourth lens group of positive refraction power. The optical zoom lens module satisfies the formula: 12<TTL/FW<16, and 6<F/F<8, where TTL is the total length of the optical zoom lens module, FW is the smallest effective focal length of the optical zoom lens module, Fis the effective focal length of the first lens group, and F is the effective focal length of the optical zoom lens module.
