Abstract: An image forming lens includes a first lens group and a second lens group. The first lens group has positive refractive power moved toward the object side when focusing from a long distance to a short distance. The second lens group has positive refractive power arranged closer to the image side than the first lens group. The second lens group includes, in order from the object side to the image side, a negative lens having a concave surface on the image side, a negative meniscus lens having a concave surface on the object side, and a positive lens. The focal length f21 of the negative lens and the focal length f22 of the negative meniscus lens satisfy the following conditional expression: (1) 0.1

Abstract: An optical magnification system includes a lens barrel, a lens seat, a bush and a fixing element. The lens barrel has a slot. The lens seat includes a seat body and a sliding portion, wherein the seat body is movably disposed within the lens barrel, and the sliding portion is disposed on the seat body, extends into the slot and is configured to slide within the slot. The bush is movably disposed on the lens barrel. The fixing element extends through the bush and the sliding portion and is fixed to the seat body. The lens seat is configured to move relative to the lens barrel and along the slot via the sliding portion. The lens seat and the bush are respectively forced against the inner circumferential surfaces and the outer circumferential surfaces of the lens barrel by the fixing element.
