A camera adjustment mechanism for adjusting the relative orientation of a lens (4) and an image recording unit (5). The mechanism comprises:
- a first control ring (7) provided with a first control ring thread (8), rotatable by a user with respect to a first reference portion (6) of the mechanism (1) about a first, at least imaginary, axis (L1);
- a movement element (9) rotatable with respect to the first reference portion about a second, at least imaginary, axis (L2) for, depending on rotation of the first control ring about the first axis, relatively at least rotating, on the one hand, the lens and, on the other hand, the image recording unit about the second axis, which movement element is provided with a movement element gearing (10); and
- a worm wheel (11) with double gearing (14, 15), rotatable with respect to the first reference portion about a third, at least imaginary, axis (L3), comprising a first worm wheel gearing (14) and a second worm wheel gearing (15), wherein groove directions (14a, 15a) of the first worm wheel gearing and the second worm wheel gearing, respectively, differ from each other, which worm wheel is situated between the first control ring (7) and the movement element (9). |
