The focusing state determining adapter is detachably mounted between an interchangeable taking lens and a camera body in a camera system. The focusing state determining adapter includes a focus-imaging element and a beam splitter, which divides the subject light entering through the taking lens into light entering the focus-imaging element and light entering the camera body. The focusing state determining adapter determines the focusing state of the taking lens according to an image captured by the focus-imaging element.
