A viewfinding system for use with an optical system that creates a first object image includes an objective block which is sealed as a unit. The objective block includes a focusing screen for forming the first object image and relay optics for transmitting the first object image. A zoom block includes a zoom optical system for providing a modification of the magnification of the first object image to provide a second object image. An eyepiece block receives the second object image and includes a reflecting member and an eyepiece through which the second object image is observed. The eyepiece block is sealed and the second object image is realized within the sealed eyepiece block.
