Arca-Swiss Dovetail vs. ARRI Rosettes & Pins
Comparing 2 standards across 12 specifications. 12 key differences identified.
The Arca-Swiss Dovetail (introduced by Arca-Swiss Phototechnik in the 1990s) is widely regarded as the de facto global quick-release standard in professional photography. Featuring a 38.0 mm wide aluminum plate with precision 45-degree chamfered edges, it clamps into screw-knob or lever-release tripod heads with rigid mechanical zero-play locking.
The ARRI Rosette (31.8 mm diameter with 60 radial teeth and an M6 central thread) and ARRI 3/8"-16 Anti-Twist Locating Pins (dual 3.0 mm indexing holes flanking a 3/8"-16 screw) are the de facto cinema rigging standards developed by Arnold & Richter Cine Technik (ARRI) to prevent camera cage accessories from twisting under heavy rotational torque.

Clamp Compatibility
|
Screw-knob clamps accommodate minor ±0.5mm plate width variations; cam-lever clamps require exact 38.0mm precision | — |
|
ARRI Rosette Outer Diameter
|
— | 31.8 mm (1.25 in) |
|
Tooth Configuration
|
— | 60 radial interlocking teeth (enables precise 6.0° rotational index adjustments) |
|
Rosette Center Bolt
|
— | M6 × 1.0 mm internal metric thread (or 1/4"-20 on some consumer cages) |
|
ARRI 3/8"-16 Anti-Twist Pattern
|
— | Central 3/8"-16 screw flanked by two 3.0 mm locating pin holes at 15.0 mm spacing |
|
Primary Applications
|
— | Cinema handgrips (ARRI Alexa, RED, Sony Venice, FX9), extension arms, heavy top handles, monitor arms |
|
Torque Resistance
|
— | Highly resistant to rotational slippage when properly seated, since the teeth physically mesh together rather than relying on friction alone |
