LENS ASSEMBLY AND IMAGE-TAKING APPARATUS |
摘要 |
A lens assembly includes a barrel having an object-side opening and an image-forming-side opening. The barrel further has a positioning section that positions an image-forming-side surface of a lens by having line contact around an optical axis at a center. The positioning section is disposed at a position that is closer to an object side than the image-forming-side opening of the barrel is. The barrel also has an image-forming section that extends from the positioning section to a center of the optical axis along the image-forming-side surface of the lens and forms an edge of the image-forming-side opening of the barrel.
