Abstract
In a photographic camera having a long focal length objective, both the objective and a tubular viewfinder extend vertically upwardly adjacent one another from the film carrying part of the camera which facilitates support of the camera in use. Preferably the objective and viewfinder are formed as a periscope arrangement with the light-admitting end of the objective being higher than the eyepiece of the viewfinder.
