Abstract: A viewfinder mounting for mounting a viewfinder on a camera body for adjustable movement in a common plane in two directions perpendicular to each other. This viewfinder mounting includes a first slide mechanism including first and second slide members coupled with each other for sliding movement relative to each other, and a second slide mechanism including third and fourth slide members coupled with each other for sliding movement relative to each other. A camera fixture is employed to connect the first slide member to the camera body, and a viewfinder fixture is also employed to connect the fourth slide member to the viewfinder. A holder connects the second and third slide members with each other to render the first and second slide members to lie perpendicular to each other. A slide lock mechanism is provided for releasably locking the viewfinder fixture and the camera fixture relative to each other.
