Description

Photo-Kino-Kamera mit Spiegelreflex@ucher. allgemeines: Nach dem Stand der Technik sind Photo-Kino-Kameras mit Spiegelreflexsuchern ausgestattet, bei denen das Sucherbild etwa die gleiche Grösse besitzt wie das Aufnahmobild. dies erfordert eine relativ grosse Raumgestaltung, sodaß solche Kameras erhebliche Ausmaße aufweisen. Deuchreib Die vorliegende Erfindung beruht darauf, i daß für den Spiegelreflexsucher eine kleinere Abmessung r en öp des Sucherobjektives und der übrigen Bauelemente verwendet wird,wobei das Grössenverhältnis zwischen Aufnahneobjektiv und Aufnalmeformat und Sucherobjektiv und Sucherfeld ioaer gleichlaufend bleibt. Beispiels Aufnahmebrennweite 8 cm, Aufnahsebildformat 6 x 6 cm, Sucherbrennweite 4 cm, Sucherformat 3 x 3 cm. Um die bei de Verkleinerung des Sucherbildes eintretende grössere Tiefenschärfe des Sucherobjektives und damit schuleriere nattscheibenbeurteilung der Einstellschärfe su überbrücken, uird sweckEässig eine Mattscheibe mit sogenannten nesskeilen verwendet.

Photo cinema camera with mirror reflex@ucher. General: According to the state of the art, photo cinema cameras are equipped with reflex viewfinders, in which the viewfinder image is about the same size as the recording image. this requires a relatively large spatial design, so that such cameras have considerable dimensions. Deuchreib The present invention is based on i that for the SLR viewfinder a smaller dimension r en öp of the viewfinder lens and the other components is, where the size ratio between the recording lens and recording format and viewfinder lens and viewfinder field ioaer remains concurrent. Example focal length 8 cm, recording image format 6 x 6 cm, viewfinder focal length 4 cm, viewfinder format 3 x 3 cm. To the de reduction of the viewfinder image greater depth of focus of the viewfinder lens and thus school the focus disc assessment of the sharpness bridge it below, and use a screen with it so-called ness wedges are used. Utility model Grana'prH. shes 1,,) Photo-KinD Camera. with mirror reflex viewfinder, thereby gekennsGichnety that the focal length of the viewfinder lens and the viewfinder field of view is smaller iGt than the focal length of the Recording lens and the recording image format, but jeueila always has the same image section, 2.) Photo-cinema-Hsmera with SLR viewfinder as described under 1.), characterized in that the viewfinder image can be viewed directly on the screen or via an inverting prism. 3.) PhotoKino Esmera. isit mirror flex viewfinder as below 1) and 2) described, characterized in that ., ur E,. relief* of the Sehari sur facilitating the focusing of the viewfinder image a nut disc with wedges can be used.
