FREEWELL 82mm Empty Base Ring for Magnetic VND Filter System
An 82mm empty base ring that provides a magnetic mount for Freewell VND filters
- Designed for Freewell Magnetic VND Filter System only
- Fits lenses with 82mm filter thread for secure mounting
- Enables quick magnetic filter swaps in changing light
- Durable construction withstands frequent professional use
- Empty base ring adds no optical elements to light path
Purpose & Audience
The 82mm Empty Base Ring is a dedicated mount for the Freewell Magnetic VND Filter System. It threads onto lenses with an 82mm front filter thread and provides the magnetic docking point required by that system. Professional photographers and enthusiasts who already own the Magnetic VND filters use this ring to add compatible lenses to their kit.
What the Ring Enables
Once fitted, the base ring lets you attach and remove the Magnetic VND filters in seconds without screwing them on. This quick-swap capability helps you react to changing light or creative intent during a shoot. The ring itself contains no glass or variable-density mechanism; it is purely the interface that makes the magnetic filters work on an 82mm thread.
Interface Constraints
The ring works only with the Freewell Magnetic VND Filter System and will not accept standard screw-in filters or other magnetic filter brands. It requires an 82mm filter thread on the lens, so lenses with different thread sizes need their own specific base ring. Vignetting performance depends on the lens focal length and filter stack, which this ring does not control.

Questions about this item
Will the 82mm base ring threads wear out from repeated magnetic filter swaps?
The aluminium ring threads are rated for thousands of mount cycles; normal daily changes will not strip them.
What stops me from stacking more magnetic filters once the VND is on the 82mm ring?
The magnetic VND sits flush on the base ring, leaving no exposed threads for a second filter.
Does the 82mm ring get hot enough to affect focus during long video takes?
The passive metal ring adds no heat of its own; lens temperature stays unchanged.
