Low-breathing-effect large-aperture photographic lens

The invention relates to the technical field of optical imaging, in particular to a low-breathing-effect large-aperture photographic lens. The first lens group, the second lens group and the third lens group are sequentially arranged from an object side to an image side; the first lens group is composed of a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The second lens group is composed of an eighth lens, a ninth lens and a tenth lens which are sequentially arranged from the object side to the image side. The third lens group is composed of an eleventh lens, a twelfth lens and a thirteenth lens which are sequentially arranged from the object side to the image side. The focal length between the first lens group and the second lens group satisfies the following relationships: 1.30 lt; f1/f2lt; 1.55, 1.55; wherein f1 is the focal length of the first lens group, and f2 is the focal length of the second lens group. The invention provides a low-breathing-effe
