The fire concerns a photographic camera. Voi the one Kornril and one telephoto lens v.-ahlv.-eir? individually or reinsa "in de ~ Aufnahn: estrahleng-.n. ~ the same are to be arranged. For such known arrangements should a simple adjustment device was created.

It is suggested for this purpose that the I "or ~ aobjective and the telephoto lens are each arranged on a slide that can be displaced parallel to the plane, and both Sliders are coupled by a zv; elärmigen lever that the pivot point of the lever can be adjusted parallel to the pilnecene and that the slides can be moved by an adjuster. It is useful that a slide under the Effect of a spring cteht that adjusts a slide can follow positively. Furthermore, for easy setting and display of the same, it is advantageous that

the fulcrum of the lever by a vcitoren dial is adjustable and InTi sit dom another adjuster a display field 3 is connected to reading windows. the can be moved via display representations.

Further advantages and details of the delivery will be given explained in more detail with reference to drawings. Zs tend

The locking circuit board is from a photographic camera 1 with the closure passage opening 1a, the image plane 2 as well as a 2 setting slide 3 for preselecting the IToraal lens 4 or the telephoto lens 5 and a Zinsteller 6 shown for close-up setting.

slidable slides 7ι 8 in their: correct distance from the plane 2 stored. A slide 8 is under the action of a spring 9 which ^{seeks to} pull it and the lens & into the utility box in which the Cb.jektiv 4-lies in front of the shutter opening la. The two slides 7> 8 are coupled to one another by a two-armed lever ΊΟ, for example via pin-and-slot connections 8a, 10a or 7a, 10b. The lever "0" can only be rotated by an axis 11, which can be displaced by the adjuster 6 into two positions 11 and 11 '.

The adjuster 6 is also connected to a reading field 6a, which has two reading windows 6b, 6c. Uivte? ¹ the reading field 6a are the designations "Nah", ^:! Tele "," Normal "attached. The adjuster 3 can be moved over the reading field 6a, assigned to the reading windows 6b, 6c Lockable ball catch 12. The slide 7 is in a force-locking manner under the coupling effect

The adjuster 6 is in the position according to FIG. 1 in the position in which close-ups are not possible. The information is thus in the reading windows 6b, 5c "IeIe" or 'IIormai "can be seen. The pointer 3c of the tin plate 3 is opposed to the note "TeIe", w-cbei the telephoto lens 5 lies in the recording beam path la, 2.

As a result, under the action of spring 9, slide 7 r. &. Ch move to the right and slide 8 to the left,

so that the telephoto lens 5

be pushed into the recording beam path 1a, 2.

If, instead of taking pictures with the normal or telephoto lens, one wants to take close-up pictures, then both objectives 4 must be arranged at the same time in the recording beam path 1 a, 2. For this purpose, shifts m-.n from the, position shown in FIG ^Λ interest plate 6 leftward to the position shown in Figure 2 Location ". Thereby, in addition to the telephoto lens 5 and the normal lens 4 in the recording beam path, and
