摘要： Providing a zoom lens system that has a high zoom ratio, high optical performance, and compactness, and is easy to be manufactured. The 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, a third lens group having positive refractive power, and a fourth lens group having positive refractive power. Zooming from a wide-angle end state to a telephoto end state is carried out by moving each lens group along the optical axis such that a distance between the first lens group and the second lens group increases, a distance between the second lens group and the third lens group decreases, a distance between the third lens group and the fourth lens group decreases. A zoom ratio is 5.0 or more. Given conditional expressions are satisfied.

摘要： A camera having a manually actuable switch for temporarily shifting the camera to an optimum exposure value so that exposure factors, based upon a manually set shutter speed and a manually set aperture value, are replaced by optimum exposure factors based upon a metered brightness of the object to be photographed when the camera is set to a non-program exposure mode. A clear button associated with the camera functions as a manually actuable switch for temporarily shifting an exposure mode of the camera to another exposure mode when the camera is set to a hyper-manual exposure mode. In the hyper-manual exposure mode, a photographer sets exposure factors by actuating a Tv electronic dial and an Av electronic dial. Actuation of the clear button when the camera is set to the hyper-manual exposure mode causes the set exposure factors to be replaced with optimum exposure factors that are automatically calculated in accordance with an object brightness Bv. Thus, operating the clear button (manually actuable switch for temporarily shifting to another exposure mode) results in the mode of the camera being changed from a mode in which exposure factors are manually set by a photographer (via the setting of a shutter speed and an aperture value) to a mode in which optimum exposure factors are set based upon a calculation performed by a processor of the camera.
摘要翻译：一种具有手动开关的照相机，用于临时将相机移动到最佳曝光值，使得基于手动设定的快门速度和手动设定的光圈值的曝光因子被基于对象的计量亮度的最佳曝光因子所替代当相机设置为非程序曝光模式时要拍摄。与相机相关联的清除按钮用作手动开关，用于当相机设置为超手动曝光模式时将相机的曝光模式临时移动到另一曝光模式。在超手动曝光模式中，摄影师通过启动电视电子拨号盘和Av电子拨盘来设置曝光因素。当相机设置为超手动曝光模式时，清除按钮的启动使得设置的曝光因子被替换为根据对象亮度Bv自动计算的最佳曝光因子。因此，操作清除按钮（用于临时移动到另一曝光模式的手动开关）导致相机的模式从摄影者手动设置曝光因子的模式（通过快门速度和光圈值）到基于由照相机的处理器进行的计算而设定最佳曝光因子的模式。

摘要： A zoom lens includes a front or first lens group having a positive power and a rear lens group having a variable positive power, arranged in this order from an object side. The first lens group includes at least one negative lens and at least one positive lens. The negative lens of the first lens group is located closest to an object and is provided with a concave surface located on an image side. The concave surface is made of an aspherical surface whose radius of curvature increases to reduce the negative power as the height of the concave surface from the optical axis increases. The aspherical surface satisfies the formulae:0.2
