Arca Swiss D4 GP Geared Panning Tripod Head with MonoballFix Device
The D4 Tripod Head with it's unique design and innovative construction has been further developed and enhanced with the addition of an optional gear driven self-locking panning device situated directly below the camera quick release.
This new upper geared panning device can also be set to a free movement mode for fast camera positioning or smooth continuous movement by simply pulling the panning knob outwards. To re-engaged the precise geared camera rotation push the panning knob inwards.
The ARCA-SWISS D4 Tripod Head with MonoballFix Quick Release is a symbiosis between a spherical head and a 3D tilt head, and has the combined advantages of both systems in one head. The head features both top and bottom panning devices for accurate rotational stitching.
The head is small and compact, and the levers are arranged efficiently so they do not get in the way. On a tripod, the D4 Tripod Head can be used like a normal spherical head.
If the X- and Y-axes are open, you can move the camera freely. The D4 head allows you to perform the movements separately, one at a time. This can even be done with both the axes open; if one of the axes is fixed, this may be performed even more precisely.
The D4 unit has two panoramas. A rotating device, which allows camera alignment, is found on the base of the head. The second geared panorama is above the axes and allows the performance of a panorama shot with an already aligned camera.
The D4 head's innovative design puts the centre of rotation of the X and Y movements in the same place, making the pivoting radius of these movements very small, thus allowing you to maintain perspectives already found during readjustment.
The head's swiveling is equipped with a self-locking shock absorption feature, allowing for near total compensation of the camera's weight. Another notable feature is the positioning of the spirit levels, which are located underneath the upper panorama adjustment and are arranged at a 90° angle. Both are sufficiently visible as to facilitate effective leveling, even from a low viewpoint.
