摘要： Wide-angle large-aperture zoom lens provides a field angle greater than 75° at the wide-angle end and a variable magnification power of 2.5 or greater, and can downsize a compensation mechanism for image blur due to hand tremors. The zoom lens includes a first lens group LG1 of positive refractive power, a second lens group LG2 of negative refractive power, a third lens group LG3 of positive refractive power, and a fourth lens group LG4 of positive refractive power, all arranged in sequence from the closest to an object to the closest to an imaging plane, and permits magnification power to vary by varying clearances between adjacent ones of the first lens group LG1 to the fourth lens group LG4. Part of the lens pieces in the third lens group is moved orthogonally to the optical axis to compensate for image blur due to hand tremors.

摘要： A zoom lens includes, sequentially from an object side, a first lens group having a positive refractive power; a second lens group having a negative refractive power; a third lens group having a positive refractive power; and a fourth lens group having a positive refractive power. Zoom is performed by moving the second and the third lens groups in a direction along an optical axis. The fourth lens group consists of, sequentially from the object side, a front group having a positive refractive power, an intermediate group configured by a cemented lens formed by a positive lens and a negative lens and having an overall refractive power that is negative, and a rear group having a positive refractive power. Blur is corrected by moving the intermediate group in a direction that is substantially orthogonal to the optical axis.
