the format that can be used for projection. When used exactly in accordance with the viewfinder image, under certain circumstances Parts that are important to the image are lost during projection, while the other way round if the slide format is roughly taken into account parts that are not important to the image become visible during projection.

The adjustment of the viewfinder image field exclusively to the slide format limits that for the production of paper images usable format. If the viewfinder image is set precisely to the subject, the image window opposite the image window Deviation of the edge of the negative not used, so that this may be in parts that are not important for the image The edge of the images is reflected.

Further details of the invention are the description of two exemplary embodiments, but without referring to them Restrict, as well as to be taken from the claims.

The graphic representations show in the

Fig. 1 is a partial section through the partial view of a single-lens reflex camera,

Fig. 2 is a plan view of a glass plate with etched Frame, according to the slide format and its holder,

3 shows a section through a plastic plate with a molded frame.

On the front of the housing 1 of the single-lens reflex camera, the object shutter 2 and the taking lens 3 are mounted. The beam coming from the taking lens is thrown from the mirror, not shown, onto the matt surface 4 a of the disc 4 and forms the viewfinder image on the surface 4 a. This image reaches the viewer's eye via the viewfinder lens 5, the pentagon prism 6 and the viewfinder eyepiece 7.
