Abstract
A variable focal length camera has a lens barrel movable parallel to the optical axis of its taking lens system so as to change over the focal length of the taking lens system at least between a standard photography position and a telephoto position. When the subject distance is nearer than the nearest focusable distance for standard photography or for telephotography, the lens barrel is automatically moved into a first close-up position if the lens barrel has been in the standard photography position, whereas the lens barrel is moved into a second close-up position if the lens barrel has been in the telephoto position.
