Abstract
Methods and apparatus for using optical chains, e.g., camera modules, with different lens configurations to support a wide range of focal lengths are described. In some embodiments a camera device includes a plurality of optical chains. In at least some embodiments non-circular outer lenses are used for optical chains with large focal lengths while optical chains of the same camera device which have smaller focal lengths use round outer lenses. Thus an exemplary camera device supports a number of different focal lengths.
