REAL IMAGE TYPE FINDER

PURPOSE:To manifest a crosswise spread feeling by increasing the magnification of a finder when it is turned to a panoramic size and simultaneously changing the aspect ratio. CONSTITUTION:This finer is provided with an objective lens system 1, a first imaging surface 2 by means of this objective lens system 1 and a relay lens system 3 for re-imaging a body image formed on the first imaging surface, and a second imaging surface 5 re-images an image formed on the first imaging surface 2 on this surface 5. An eyepiece 6 is one that observes an image on the second imaging surface 5, thus a real image finder system is composed of these elements. The relay lens system 3 is selected to another relay lens system 4 by this finder optical system, through which the extent of magnification in the body image being observed with the eyepiece 6 is increased, while, for example, a field diaphragm placed on the first imaging surface 2 is replaced with another field diaphragm different in an aspect ratio with a panoramic size aspect ratio. With this constitution, it is replaceable to a panoramic finder with a crosswise spread feeling, thus an ordinary finder is made selectly usable as a panoramic finder.
