Lens system with a high zoom amount to the far angle detection in the case of a a compact camera

摘要

lens system with a high zoomverhu00e4ltnis, a wide angle for a compact camera is recorded and a first linsengruppe with a positive focal length and a second linsengruppe (iia, iib) with a positive focal length, and a third linsengruppe with negative focal length, the succession and, on the basis of the gegenstandsseite, are arranged.the zooming of a short focal length to a long focal length range, the entire first linsengruppe, the second and the third linsengruppe linsengruppe against the aufnahmeobjekt moves, so that the distance between the first and the second linsengruppe will increase linsengruppe t, and the interval between the second and the third linsengruppe linsengruppe reduced.the second linsengruppe includes sequentially, starting from the side of the aufnahmegegenstands, a linsengruppe with a negative focal length and a linsengruppe with a positive focal length. when zooming from the short focal length of long focal length field is an aperture (a) together with the second linsengruppe moved. the specific conditions are fulfilled.
