ABSTRACT Object: To provide an optical system and optical apparatus which can be expanded and tilted wituout rotating an image itself. Constitution: There is a series of light paths successively formed via reflecting members, said light paths including at least five optical axes from a first optical axis to a fifth optical axis constituting center axes thereof, the second axis and the fourth axis being parallel with each other, one ends on the same side thereof being perpendicular to both ends of the third optical axis, as a result of which the second axis, the third axis and the fourth axis are arranged in the same plane in the form of ? shape, one ends of the first axis and the fifth axis being perpendicular to the other ends of the second optical axis and the fourth optical axis, the first optical axis and the fifth optial axis extending in the opposite directions when all the axes from the first optical axis to the fifth optical axis are placed in the same plane, and the first optical axis and the fifth optical axis being associated to be rotatable in symmetrical synchronism with each other about the second optical axis and the fourth optical axis.
