Abstract:
Comprising a positive first lens group G 1  disposed at a most object side, a negative intermediate group G 2  disposed at an image side of the first lens group G 1 , a positive focusing group G 3  disposed at an image side of the intermediate group G 2 , the focusing group G 3  being moved upon focusing, and a positive image side group G 4  disposed at an image side of the focusing group G 3 ; upon varying magnification, a distance between the first lens group G 1  and the intermediate group G 2 , a distance between the intermediate group G 2  and the focusing group G 3  and a distance between the focusing group G 3  and the image side group G 4  being varied; and a predetermined conditional expression being satisfied. Whereby a variable magnification optical system having excellent optical performance and a focusing lens group reduced in weight in order to attain high speed focusing operation, and others are provided.

Claim (Index 13):
