Optical lens assembly

An optical lens assembly, comprising:

• a lens barrel;
• five lenses, the five lenses comprising a first lens, a second lens, a third lens, a fourth lens, and a fifth lens sequentially from an object side to an image side;
• a first spacer, in contact with at least part of an image-side surface of the first lens;
• a second spacer, in contact with at least part of an image-side surface of the second lens;
• wherein a focal length f2 of the second lens, a center thickness CT2 of the second lens on the optical axis, an air spacing T23 on the optical axis between the second lens and the third lens, a maximum thickness CP2 of the second spacer, and a distance EP12 between an image-side surface of the first spacer and an object-side surface of the second spacer along the optical axis, satisfy:
• −50.0<f2/(CT2+T23)+f2/(EP12+CP2)<0.
