ABSTRACT:
A view finder of a camera includes a taking optical system, and a finder optical system which is separate from the taking optical system. The view finder has a normal photographic mode and a macro photographic mode. The finder optical system includes a field frame having a photographic field correcting mark at a close object distance in the normal photographic mode, and a variable power lens group for varying the magnification of the finder, so that the variable power lens group decreases the finder magnification in association with the shift from the normal photographic mode to the macro photographic mode.
