Abstract
The taking lens comprises a picture-taking optical system, which allows object light to enter an image-capturing element for picture-taking of a camera, and a focus determination optical system, which splits the object light and allows the split light to enter a focus status determination image-capturing element. The taking lens includes a picture-taking optical length adjusting device, which adjusts an optical length of the picture-taking optical system, and a focus determination optical length adjusting device, which adjusts an optical length of the focus determination optical system. It is hence possible to adjust the respective optical lengths separately and facilitates adjustments at the time of shipment.
