retractable lensとは 意味・読み方・使い方

To provide a lens barrel that has a retractable optical element, movable between the position where the optical element is advanced on a photographic optical axis and the position, where it is separated from the photographic optical axis, with the lens barrel being designed so as to surely stop and hold the retractable optical element at the advanced position on the photographic optical axis.例文帳に追加
