摘要: The disclosed zoom lens includes, from front to rear, a magnification-power variable assembly which serves for zooming and an image forming is stationary during zooming. has component B of negative refractive power preceded by at least one A movable focusing followed C focusing. This structure makes achievement compact form good stability in aberration correction possible throughout the entire range.
