摘要: A zoom lens including, from front to rear, a positive first component, a negative second component, a positive third component and a fourth component which is stationary during zooming. In some zoom lenses, a fifth component may be positioned behind the fourth component, in which, during zooming, the fourth component is movable and the fifth component is stationary. The separation between the first and second components and the separation between the second and third components varies to effect zooming. The third component is composed of, from front to rear, two positive lenses, a negative meniscus lens having a divergent cemented surface convex towards the front, and a positive lens with its rear surface having the stronger curvature. Minimization of bulk and size and an increase of the image magnification range of the zoom lens is achieved while preserving correction if aberrations.
