摘要:
A camera is described with objective lens and image reception carrier equipment and a focussing process. From related extension measured distances (x1-x2, x2-x3, .delta.b), final adjusted, set-point focus values (.theta..sub.soll, .PHI..sub.soll) are obtained in the course of the focussing of various image points (B1, B2, B3) for a multiply pivotable, bellows camera which produces the pivoting angles (.alpha., .beta., .theta., .PHI.), the latter used for a double focussing compensation; by this means, the direct making of an exact spatial interval distance measurement between the objective lens carrier (OT) and the and image carrier (BT) is dispensed with, since at least a relatively accurate extension measurement (.delta.b) at a predetermined objective lens setting is obtained and evaluated. The optical bench (OB) can be equipped with a raster arrangement for the image carrier (B1), the objective lens carrier (OT) and be constructed in sections (OB1, OB2).
