Abstract

1337053 Inter-changeable lens carrier PENTACON DRESDEN KAMERA-UND KINOWERKE VEB 14 Oct 1971 47947/71 Heading G2A A photographic apparatus which may be an enlarger has two alternative lenses 2, 3, of different focal lengths, mounted on a sliding carrier 1, so that either may be brought into alignment with the optical axis O of the apparatus, and the lenses are positioned by engagement of a relevent one of adjustable stops 15, 16 with the carrier body while the corresponding end 5 or 6 of the carrier is adjacent to, and attracted by, a fixed magnet 12 or 13 or the end of its sliding travel. The lenses 2, 3 are coupled by a gear wheel 4, so that they do not require refocussing when the carrier is moved to change one for the other.
