Optical photography lens system, image capturing unit and electronic device

Abstract

An optical photography lens system includes a lens barrel and a plurality of lens elements disposed in the lens barrel. The total number of the plurality of lens elements is six, seven or eight. Each of the plurality of lens elements has an object-side surface facing toward an object side and an image-side surface facing toward an image side. At least one of the object-side surface and the image-side surface of at least one lens element of the optical photography lens system has an inflection point. The optical photography lens system further includes a light-blocking element located in the lens barrel and located on an object side of the first lens element. The lens barrel has a lens-barrel-minimum opening located on an object side of a minimum opening of the light-blocking element. When specific conditions are satisfied, the requirements of high manufacturing quality and high image quality can be met by the optical photography lens system, simultaneously.
