Abstract

A camera has an infinity end stopper that stops a lens holder to a position which sets a best focal length at infinity, and a macro-side stopper that stops the lens holder to a position at which the best focal length becomes a predetermined length. In normal mode, the camera abuts the lens holder on the infinity end stopper and then moves the lens holder toward the macro-side stopper to perform auto focus. In macro mode, the camera abuts the lens holder on the macro-side stopper and then moves the lens holder toward the infinity end stopper to perform auto focus. This can suppress a variation in the position of the camera after lens movement.
