ARCA-SWISS d4 “monoball®Fix”

Precision in three dimensions. Compact, controlled, uncompromising.

The ARCA-SWISS d4 “monoball®Fix” is a high-precision 3D geared head that combines the mechanical accuracy of the d4 with the flat, vibration-free monoball®Fix quick release system. With micrometric control on two axes and free rotation around the vertical axis, the d4 provides absolute control over image alignment and perspective – perfect for precise studio, architectural, and landscape photography.

Two panoramic axes – one at the base and one beneath the camera plate – allow precise alignment and panoramas without changing the shooting level. The precision-milled aluminum housing and self-locking gearing ensure millimeter-accurate movements with maximum stability.

Key Facts

Conclusion – Who is it for?

• For photographers using technical or heavy camera systems,
• For architectural, landscape, and studio photography demanding maximum precision,
• For users of the monoball®Fix system who seek maximum stability and direct locking,
• For anyone combining geared precision, compact design, and vibration-free connection.

How does the “monoball®Fix” quick release work?

The monoball®Fix system uses a precise, low-profile clamping mechanism. The camera plate is locked directly by a rotation or short lever movement – fast, play-free, and form-fitting. The reduced height minimizes vibrations and provides an even more stable connection between camera and head.

Important note: The monoball®Fix system is precisely matched to the dimensions of original ARCA-SWISS monoball®Fix plates. Only genuine plates should be used, as third-party products with dimensional tolerances may affect clamping performance and safety.
