ABSTRACT:
A relay lens system which may be used with, e.g., a video camera or still video camera so that these video cameras can use, as the image forming lens, various preexisting interchangeable image forming lenses originally designed for single lens reflex cameras. The image forming lenses which form a first image can have various exit pupils. The entry pupil of the relay lens system can be changed in accordance with each particular exit pupil by selecting one from a plurality of apertures or by a movable aperture. Consequently, a second image can be formed that reproduces the first image while maintaining good quality.
