Zoom Lens Assembly

A zoom lens assembly, sequentially comprising, from an object side to an image side along an optical axis thereof:

• a first lens group, multiple lenses in the first lens group being spaced;
• a second lens group with a positive refractive power, multiple lenses in the second lens group being spaced;
• and
• a third lens group with a negative refractive power, multiple lenses in the third lens group being spaced, wherein the second lens group and the third lens group move along the optical axis to implement continuous zooming;
• the zoom lens assembly has a wide-angle end position, a middle end position and a telephoto end position;
• and
• EPD is an entrance pupil diameter of the zoom lens assembly, ImgH is a half of a diagonal length of an effective pixel region on an imaging surface of the zoom lens assembly, DTmax is a maximum value in effective radii of each lens in the first lens group, the second lens group and the third lens group, EPD and ImgH and DTmax satisfy:
• EPD*ImgH/DTmax>6.5 mm.
