摘要： An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens sequentially arranged along an optical axis from an object side toward an image side. The fifth lens has positive refractive power, a focal length of the fifth lens is smaller than an overall focal length of the optical imaging system, and −0.38≤R10/f≤−0.32, where R10 is a radius of curvature of an image-side surface of the fifth lens and f is the overall focal length of the optical imaging system.

摘要： A lens assembly includes a lens including an optical portion refracting light and a flange portion extending along a portion of a circumference of the optical portion, a blocking member disposed in front of the lens and having an opening to allow light to be incident on the lens, and a lens barrel accommodating the lens. The optical portion is noncircular and a portion of the blocking member facing the optical portion in an optical axis direction is located to be higher than a portion of the blocking member facing the flange portion in the optical axis direction.
