摘要： An optical system includes, in order from an object side, a first lens unit having positive refractive power, a second lens unit having negative refractive power, and a third lens unit having positive refractive power. A distance between adjacent lens units changes during focusing. During focusing from an infinity object to the closest object, the first and third lens units do not move and the second lens unit moves toward the image side. The third lens unit consists of, in order from the object side, a first subunit having positive refractive power, a second subunit having negative refractive power, and a third subunit having positive refractive power. The second subunit moves in a direction including a component in a direction orthogonal to an optical axis during image stabilization. The second subunit includes positive and negative lenses. A predetermined condition is satisfied.

摘要： The imaging lens consists of, in order from the object side, a first lens group having a positive refractive power, a second lens group having a negative refractive power, and a third lens group having a positive refractive power. The first lens group has a positive lens, a positive lens, and a negative lens successively in order from a position closest to the object side. The second lens group consists of one negative lens. The third lens group includes two or less lenses. During focusing, only the second lens group moves. The following conditional expression, which relates to a focal length f of the whole system in a state where the object at infinity is in focus and a focal length f2 of the second lens group , is satisfied: 0.4

摘要： A relay system includes a first lens group formed of a plurality of lenses and having positive power, a second lens group including a diaphragm and at least one negative lens and having negative power, and a third lens group formed of a plurality of lenses and having positive power. The number of lenses of the first lens group and the number of lenses of the third lens group are equal to each other. The arrangement of the lens power of the plurality of lenses of the first lens group, which are arranged from the enlargement side toward the reduction side, is the same as the arrangement of the lens power of the plurality of lenses of the third lens group, which are arranged from the reduction side toward the enlargement side. The enlargement-side and reduction-side portions of the relay system are telecentric portions.
