摘要： The zoom lens consists essentially of a positive first lens group, a negative second lens group, an aperture stop, a third lens group, a positive fourth lens group and a fifth lens group in this order from the object side. The first, third, and fifth lens groups are fixed while the second and the fourth lens groups move when changing magnification from the wide angle end to the telephoto end, and the fourth lens group moves when focusing is performed. The fifth lens group consists essentially only of a single cemented lens having a meniscus shape with a convex surface toward the image side, and conditional formulas (1), (2) are satisfied when the maximum image height is Y, the air equivalent back focus is Bf and the distance along the optical axis from the aperture stop to the peak of the most-image-side lens surface is Lsr: 0.05

摘要： A projection display apparatus includes an image display element for displaying an image on a reduction side conjugate plane and a projection optical system for magnifying and projecting the image onto a screen which is a magnification side conjugate plane as a conjugate image. The projection optical system substantially consists of a dioptric system and a catoptrics system having a common axis. The center of a display surface of the image display element is disposed eccentrically with respect to the optical axis and, when a magnification side conjugate position of the center of the display surface is vertically above the optical axis, an intersection point between a lower light ray of a light flux focused on the bottom center of the conjugate image and an upper light ray of a light flux focused on the top center of the conjugate image falls within a predetermined range.
