A viewfinder assembly for a camera having a door for access to the interior wherein the viewfinder, when properly positioned to permit pictures to be taken, blocks the door. The assembly comprises a support barrel mounted on a camera lens and a main body section adapted to support optical elements therein. An eyepiece is at one end of the main body section and extends outwardly therefrom. The invention includes mounting means for rotatably mounting the main body section on the support barrel to permit rotation of the viewfinder assembly to a position wherein the door is no longer blocked.
