Arca-Swiss Conversion Adapter Plate for Manfrotto MVH500 Fluid Video Head

The Hejnar Photo Manfrotto MVH500 Conversion Plate is a professional-grade hardware upgrade designed to bring universal Arca-Swiss compatibility to the popular Manfrotto MVH500 series fluid heads. This adapter plate only (clamp sold separately) allows videographers and hybrid shooters to bypass the proprietary Manfrotto side-lock system. Precision CNC-machined in the USA from solid 6061-T6 aluminum, it provides an unyielding foundation for technical video work, panoramic stitching, and macro photography using Arca-style plates and L-brackets.

Note: Arca-Swiss Quick Release Clamp is NOT included in this listing.

Quick Overview & Key Features

• Improved Stability: Replaces factory components with a rigid, one-piece metal bridge to minimize vibration and eliminate "play" during tracking shots.
• Omnidirectional Mounting: Position your locking knob precisely where you want it (left, right, front, or back) to avoid interference with camera cables.
• Zero Rotational Play: Precision-milled registration ensures the plate cannot rotate once secured to the head.
