    摘要： A variable magnification optical system comprising, 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, and a rear lens group; upon varying magnification, the first lens group being fixed with respect to the image plane and each distance between the neighboring lens groups being varied; the rear lens group comprising a focusing lens group which is moved upon carrying out focusing; and the predetermined conditional expressions being satisfied, whereby it is possible to suppress superbly variations in aberrations upon varying the magnification.

    摘要： An imaging device includes an image formation optical system, a light division member configured to amplitude-divide light which has passed through at least a part of the image formation optical system, a first imaging unit configured to capture a first image formed by one light flux divided by the light division member, a second imaging unit configured to capture a portion in a second image formed by the other light flux divided by the light division member, and a driving unit configured to move the second imaging unit in a direction crossing a light path of the other light flux.
