"Photographisches oder kinematographisches Objektiv." Die Erfindung betrifft ein photographisches oder kinematographisches Objektiv, vorzugsweise Vario-Objektiv mit axial verschiebbaren optischen Gliedern. "Photographic or cinematographic lens." The invention relates to a photographic or cinematographic lens, preferably a varifocal lens with axially movable optical elements.

Bei derartigen Objektiven bereitet es mitunter Schwierigkeiten, die mechanischen Verstellmittel - z. B. Führungsstangen-im Innern der Objektivfassung unterzubringen, besonders wenn Linsen oder Linsenglieder mit großen Durchmessern in Anwendung kommen müssen. With such lenses it sometimes causes difficulties that mechanical adjustment means - z. B. Guide rods inside the lens mount to accommodate, especially if lenses or lens members with large diameters must come into use.

Gemäß der Erfindung können diese Schwierigkeiten dadurch behoben werden, wenn mindestens eines der Linsenglieder von seiner üblichen kreisrunden Querschnittsform derart verkleinert abweicht, daß im Innern des Fassungskörpers zusätzlicher Raum für mechanische Verstellmittel gebildet ist. According to the invention, these difficulties can thereby be overcome if at least one of the lens members differs from its usual circular shape Cross-sectional shape deviates so reduced that in the interior of the socket body additional space for mechanical adjustment means is formed.

Zweckmäßig wird das betreffende Linsenglied (bzw. die-glieder) mindestens an einer Seite proportional zum Bildformat abgeflacht, wobei die Ausleuchtung des Bildfeldes erhalten bleiben muß. Der Anschluß des Systems an die Kamera hat hierbei so zu erfolgen, daß die abgeflachte Seite (bzw. Seiten) zu den Formatseiten des Bildfenster ausgerichtet ist. The relevant lens element (or elements) is at least expedient flattened on one side in proportion to the image format, with the illumination of the Image field must be preserved. The connection of the system to the camera has here to be done so that the flattened side (or sides) to the format sides of the Image window is aligned.

Die Zeichnung veranschaulicht schematisch ein Ausführungsbeispiel des Erfindungsgegenstandes, wobei darstellen : Fig. 1 einen Querschnitt durch ein solches System, vorzugsweise ein Vario-Objektiv, Fig. 2 einen Winkelschnitt nach Linie lI-lI der Fig. 1. The drawing schematically illustrates an embodiment of the subject matter of the invention, wherein: FIG. 1 shows a cross section through a such a system, preferably a varifocal lens, Fig. 2 is an angled section Line lI-lI of FIG. 1.

Es bezeichnen 1 die Objektivfassung mit Anschlußteil la, 2 und 2a beispielsgemäß fest eingebaute Linsen bzw. Linsenglieder positiver Brechkraft und 3 und 3a zwischen diesen angeordnete Negativlinsen oder-glieder, die mittels ihrer Fassungen 4 und 4a in bekannter Weise durch einen Führungszylinder 5 mit Handgriff 6 axial verstellt werden können. Geführt werden die Fassungen 4 und 4a z. Bt durch parallel zur optischen Achse im Gehäuseinnern befestigte Stangen 7. Um den erforderlichen Raum für diese Stangen zur sicheren Führung der Verstellglieder zu erhalten, ist im Sinne der Erfindung beispielsgemäß die vordere Negativlinse 3 großen Durchmessers bei 3b und auf ihrer gegenüberliegenden Seite bei 3c abgeflacht ausgebildet, und zwar, wie vorerwähnt, proportional zum Bildformat, so daß die Ausleuchtung des Bildfeldes stets gewährleistet bleibt. Es könnte auch eine andere Abweichung des Linsenquerschnittes von der üblichen kreisrunden Form gewählt werden, erforderlichenfalls auch bei einem weiteren Linsenglied. It denotes 1 the lens mount with connector la, 2 and 2a for example, permanently installed lenses or lens elements with positive refractive power and 3 and 3a arranged between these negative lenses or members, which by means of their Sockets 4 and 4a in a known manner by a guide cylinder 5 with a handle 6 can be adjusted axially. The versions 4 and 4a z. Bt through Rods fastened parallel to the optical axis inside the housing 7. Around the required To get space for these rods for safe guidance of the adjusting elements is For the purposes of the invention, for example, the front negative lens 3 of large diameter at 3b and flattened on their opposite side at 3c, and as mentioned, proportional to the picture format, so that the illumination the image field is always guaranteed. There could also be some other deviation of the lens cross-section can be selected from the usual circular shape, if necessary also with another lens element.

Schutzansprüche : ---------------------------------- 1.) Photographisches oder kinematographisches Objektiv, vorzugsweise Vario-Objektiv mit axial verschiebbaren optischen Gliedern, dadurch gekennzeichnet, daß mindestens eines der Linsenglieder von seiner üblichen kreisrunden Querschnittsform derart verkleinert abweicht, daß im Innern des Fassungskörpers zusätzlicher Raum für mechanische Verstellmittel gebildet ist.Protection claims: ---------------------------------- 1.) Photographic or cinematographic lens, preferably varifocal lens with axially displaceable optical members, characterized in that at least one of the lens members differs from its usual circular cross-sectional shape so reduced that additional space for mechanical adjustment means is formed inside the socket body.
