ABSTRACT:
A variable format viewfinder for a camera comprises a pair of masking blades at least one of which is movable relative to the other to change the format of the view through the viewfinder to match the format of a picture to be taken. One of the masking blades has a plurality of format-indicators which are individually uncovered by the other blade each time at least one of the masking blades is moved to change the format of the view through the viewfinder. This permits the uncovered indicator to be seen to identify the format of the picture to be taken.
