摘要： Providing a zoom lens system having excellent optical performance, an optical apparatus, and a method for zooming the zoom lens system. The zoom lens system includes, in order from an object, a first lens group G1 having negative refractive power, a second lens group G2 having positive refractive power, and a third lens group G3 having negative refractive power. Upon zooming from a wide-angle end state W to a telephoto end state T, each distance between adjacent lens groups is varied. The first lens group G1 includes, in order from the object, a front group G1a, and a rear group G1b having negative refractive power. Focusing on the object is carried out by moving the rear group G1b along the optical axis.

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 zoom lens system includes, in order from an object side: a first lens group having positive refractive power; a second lens group having negative refractive power; a third lens group having positive refractive power; a fourth lens group having negative refractive power; and a fifth lens group having positive refractive power.

At least a portion of any one of the lens groups is moved in a direction including a component perpendicular to an optical axis, and a given conditional expression is satisfied, thereby providing a zoom lens system capable of excellently suppressing variation in aberrations upon zooming and upon correcting an image blur, an optical apparatus including the zoom lens system, and a method for manufacturing the zoom lens system.

摘要： A walking-type working machine in which a gas-container housing section (cassette-type gas container) and a carry handle are mounted to a handle post. The walking-type working machine (10) is provided with a cassette-type gas container (21) mounted to a handle post (16), which rises upward and rearward from a rear section (11a) of a working machine body (11), so as to be oriented in the longitudinal direction of the handle post. A gas engine (21) is driven by fuel in the cassette-type gas container (21). The walking-type working machine is provided with a carry handle (22) for carrying the machine. The carry handle (22) is mounted to the handle post and is formed so as to surround the cassette-type gas container. The carry handle has a grip (45).
