摘要：
A camera according to the present invention comprises a taking length whose focal length is variable. A focal length thereof is determined based on a subject distance measured by a distance measuring circuit and a relation between a subject distance and a focal length previously stored in a memory or according to a manual operation. The relation stored in the memory is changed based on a focal length determined.
