The camera (1) has two SLR optical systems in a single body and a prismatic view finder which synthesises an image from thr two outer halves of the images received through the right- and left-hand lenses (4D,4G). The camera has an automatic collimation correcting mechanism and a view finder prism (5) which is able to slide to bring the halves of the images closer together or move them apart, and a coupling for the prism movement and collimation correction mechanisms. The view finder can be made up of a number of prisms or a single prism and mirrors.
