ABSTRACT:
A camera can be converted between use for wide-angle photography and telephotography, by inserting a conversion lens into or removing the conversion lens from the optical train. A changeover ring is rotatable between two positions to effect this conversion. A flash unit moves between two positions: a raised position in which the flash unit is directly exposed, for telephotography, and a lowered position in which the flash unit is disposed behind a light diffusing plate, for wide-angle photography. Movement of the changeover ring respectively frees the flash unit for upward movement, or lowers it. A spring-urged detent releasably retains the flash unit in lowered position.
