    摘要： The invention provides a zoom lens system suitable for an image gathering system using a solid-state imaging device, having a zoom ratio of about three, a small lens length, and superb optical performance. The zoom lens system includes, in order from an object, a first lens group having negative refractive power, a second lens group having positive refractive power, and a third lens group having positive refractive power. The first lens group consists only of a negative lens and a positive lens. The second lens group includes at least two positive lenses and at least one negative lens. The third lens group consists of one lens. Zooming from a wide-angle end state to a telephoto end state is conducted by decreasing a distance between the first and second lens groups, increasing a distance between the second and third lens groups, and fixing the third lens group. Given conditions are satisfied.

    摘要： Object is to provide an inner-focusing type zoom lens system carrying out focusing by moving a portion of a first lens group suitable for an auto-focus SLR camera. A zoom lens system includes, in order from an object, a first lens group having positive refractive power, a second lens group having negative refractive power, and a third lens group having positive refractive power. Upon zooming from a wide-angle end state to a telephoto end state, a distance between the first and the second lens groups increases, and a distance between the second and the third lens groups decreases. The first lens group is composed of, in order from the object, a 1A lens group G1A having positive refractive power, and a 1B lens group G1B having positive refractive power. Focusing from infinity to a close-range object is carried out by moving only the 1B lens group G1B to the object.

    摘要： To provide a zoom lens system with a vibration reduction having a long back focal length suitable for a digital SLR camera, a high zoom ratio, and a wide angle of view of 70° or more. The system includes, in order from the object, a first positive lens group, a second negative lens group, a third positive lens group, and a fourth positive lens group. Upon zooming from wide-angle end state to telephoto end state, a distance between the first and second lens groups increases, a distance between the second and third lens groups decreases, and a distance between the third and fourth lens groups varies. The third lens group is composed of a positive front lens group and a negative rear lens group. Image plane correction upon camera shake can be performed by shifting only the rear lens group substantially perpendicularly to the optical axis. Given conditions are satisfied.

    摘要： A super-wide angle lens, sequentially from an object side, comprises a first negative lens L1, a second negative lens L2, and a third positive lens L3. The first negative lens L1 with its concave surface toward an image side has an image-side surface with a curvature larger than that on an object-side surface. The second negative lens L2 is disposed at a predetermined spacing from the first negative lens L1 and takes a negative meniscus shape with its convex surface toward the object side. The third positive lens L3 has its convex surface toward the object side.
