An optical device for use with a camera and for illuminating an object. The optical device comprises a light emitting element and a lens arranged so as to direct light from the light-emitting element to illuminate the object with light emitted from the light-emitting element. The light emitting element comprises two or more light emitting zones where light from the light emitting zones is directed from the lens in corresponding spatial angles, and the light emitting zones can be individually and selectively controlled to emit a controllable light intensity. Used with a zoom camera the device can perform a zoom corresponding to that of the camera to illuminate the object corresponding substantially to what is being photographed. |
