ARRI Dovetail

ARRI quick-release system with dovetail plate for precise, repeatable camera mounting. Reduces changeover time from 5–10 minutes to under 30 seconds.

Technical Details

The ARRI Dovetail plate measures 200mm in length as standard, with variants from 150mm to 381mm for different camera sizes. The system operates with a clamping force of up to 2000N and safely supports loads up to 50kg. The plate features 1/4"-20 and 3/8"-16 threaded holes on a 12.7mm grid, as well as anti-twist pins with a 2.5mm diameter. The locking mechanism uses a spring-loaded safety tab that prevents accidental release.

History & Development

ARRI introduced the Dovetail system in 1982 with the Arriflex 535 to replace time-consuming screw mounting. The breakthrough came in 1993 with its standardization for the ALEXA series, establishing the system industry-wide. In 2018, ARRI expanded the system with LPL mount integration and in 2021 developed the TRINITY-compatible version for gimbal applications.

Practical Use in Film

In "1917" (2019), the Dovetail system enabled lightning-fast camera changes between Steadicam, drone, and tracks during the one-shot sequences. Cinematographer Roger Deakins utilized the precise reproducibility for complex greenscreen setups in "Blade Runner 2049." The system reduces changeover times from 5-10 minutes to under 30 seconds, eliminates calibration errors, and ensures pixel-accurate repeatability for multiple takes.

Comparison & Alternatives

In contrast to Manfrotto's 501PL system (sliding plate) or the Mitchell standard, ARRI's Dovetail offers higher stability and faster operation. RED's DSMC system uses proprietary mounting pins, while Sony's FS series relies on standard screw connections. Blackmagic's URSA uses its own quick-release system but does not achieve the precision of the ARRI standard. For broadcast cameras, the ENG wedge system with 75mm balls still dominates.

From the crafts

Perspectives

Cinematographer

Ich verlasse mich täglich auf die millimetergenaue Reproduzierbarkeit – einmal eingerichtet, sitzt die Kamera nach jedem Wechsel zwischen Stativ und Gimbal exakt in derselben Position. Das spart mir Stunden an Neuausrichtung und garantiert konsistente Bildkompositionen, besonders bei VFX-lastigen Produktionen wo jeder Pixel zählt.

Director

Das System gibt mir die Flexibilität für spontane Perspektivwechsel innerhalb einer Szene – von der statischen Totale direkt zur bewegten Verfolgung, ohne dass die Crew minutenlang umbauen muss. Bei emotionsgeladenen Szenen kann ich so den Moment der Schauspieler nutzen, statt ihn durch technische Pausen zu zerstören.

Producer

Die 500 Euro Mehrkosten für ARRI-Dovetail-Equipment amortisieren sich bereits am ersten Drehtag durch gesparte Arbeitszeit – weniger Setup bedeutet mehr nutzbare Drehzeit. Bei 20-tägigen Produktionen spare ich durchschnittlich 2-3 Drehtage, was bei Tagessätzen von 15.000 Euro schnell 45.000 Euro Kostenersparnis bedeutet.
