摘要： The invention relates to a zoom lens in which tweaks to the mode of movement of lens groups and the first lens group contribute more to making sure the desired zoom ratio and optical performances and ensuring that the whole length of the zoom lens is kept short while carrying it around. The zoom lens comprises a positive first lens group G1, a negative second lens group G2 and a positive third lens group G3, and includes an aperture stop S located between the second G2 and the third lens group G3. Upon zooming from the wide-angle end to the telephoto end, the first lens group G1 moves in unison, and the second lens group G2 moves in unison. The first G1 and the second lens group G2 are positioned nearer to the object side at the telephoto end than at the wide-angle end, with an increasing spacing between the first G1 and the second lens group G2 and a decreasing spacing between the second G2 and the third lens group G3. The zoom lens satisfies conditions (1) and (2) about the power and the amount of movement of the first lens group G1.
摘要翻译：本发明涉及一种变焦透镜，其中对透镜组和第一透镜组的移动模式进行调整更有助于确保期望的变焦比和光学性能，并确保变焦镜头的整个长度在携带时保持短它周围。变焦透镜包括正的第一透镜组G 1，负的第二透镜组G 2和正的第三透镜组G 3，并且包括位于第二G 2和第三透镜组G 3之间的孔径光阑S.在变焦时从广角端到望远端，第一透镜组G1一致地移动，第二透镜组G 2一起移动。第一G 1和第二透镜组G 2在望远端比在广角端处更靠近物体侧，其中第一G 1和第二透镜组G 2之间的间隔增加，并且间距减小在第二G 2和第三透镜组G 3之间。变焦透镜满足关于第一透镜组G 1的功率和移动量的条件（1）和（2）。
