Optical Imaging Lens Assembly

An optical imaging lens assembly, sequentially comprising from an object side to an image side along an optical axis:

• a first lens group with a positive refractive power, comprising a first lens with a refractive power;
• a second lens group, sequentially comprising from the object side to the image side along the optical axis:
• a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens with refractive power respectively;
• an optical filter;
• and
• a photosensitive element;
• wherein at least one of the first lens to the sixth lens is arranged to be movable relative to the photosensitive element in a direction of the optical axis;
• effective semi-diameters of each lens in the second lens to the sixth lens progressively increase in sequence;
• and
• a maximum effective semi-diameter DT51 of an object-side surface of the fifth lens and a maximum effective semi-diameter DT32 of an image-side surface of the third lens may satisfy:
• 1.5<DT51/DT32<2.5.
