摘要： A lens module may include a first lens having positive refractive power, a second lens having refractive power, a third lens having positive refractive power, a fourth lens having refractive power, a fifth lens having refractive power, a sixth lens having refractive power, and a seventh lens having negative refractive power. An inflection point may be formed on an image-side surface of the sixth lens. A turning point may be formed on an image-side surface of the seventh lens. The first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens and the seventh lens are disposed in a sequential order from the first lens to the seventh lens.
