Bellows FL is a sophisticated, rugged, versatile bellows unit that permits infinite variations of image magnification within the limits of its minimum and maximim extensions. With a standard focal lenght lens, it offers magnifications ranging from 1x (1:1, life sized) to 3x (3:1, three times life sized). With FD and FL series lenses, semi-automatic aperture operation is preserved (lens stops down, must be reset at open aperture position). It accepts the Slide Duplicator.
