摘要： A zoom lens is constructed, from front to rear, of a first lens unit of positive power, a second lens unit of negative power, a third lens unit of positive power and a fourth lens unit of positive or negative power. When zooming from the wide angle to the telephoto end, the first and third lens units move forward at the same speed, while the second lens unit moves simultaneously in non-linearly differential relation to the first and third lens unit. The zoom lens satisfies the following conditions:0.4 fT

摘要： A zoom lens with a frontmost lens group made to have the focusing function, said focusing lens group being provided with at least one member made of a plastic material. The other part of the lens system than the focusing lens group is constructed with lenses made of materials which assure that the focal length will not vary with variation of the surrounding temperature and humidity so that when focusing is followed by zooming displacement of the image plane can be prevented.
