67-72mm Step-Up Adapter for Magnetic VND

This adapter ring connects lenses with a 67mm filter thread to filters using a 72mm thread. It is built specifically for the Freewell Magnetic VND System. Photographers who own 67mm lenses and want to use the magnetic variable ND filters in the 72mm size will find this accessory essential for expanding their kit.

Thread-Size Limits and Optical Impact

The ring bridges a 67mm lens thread to a 72mm filter thread, adding a small amount of physical length between the lens front element and the filter. This step-up can introduce vignetting on certain wide-angle lenses when used at their widest focal lengths. The CNC machined aluminum construction maintains alignment to minimise optical degradation, but the adapter cannot overcome the physical constraints of the lens hood bayonet or ultra-wide field of view.

Verify Lens Thread and Filter System Before Buying

Confirm that your lens has a 67mm front filter thread before ordering, as this ring will not fit other thread sizes. Ensure you are using Freewell Magnetic VND filters in the 72mm size, because the adapter is designed for that specific magnetic mounting system. Check whether your lens hood attaches via the filter thread; if it does, the hood may not mount over this adapter and 72mm filter combination.

Questions about this item

Should I choose the 67mm to 72mm step-up ring or a different size for my lens?

This ring adapts a 67mm lens thread to accept 72mm filters; choose it only if your lens has a 67mm front thread and your filters are 72mm.

Will using this adapter affect image quality or cause vignetting on my wide-angle lens?

The CNC machined aluminium construction is engineered to maintain optimal clarity and eliminate vignetting when stepping from 67mm to 72mm threads.

Does the magnetic VND system use a standard filter thread or a proprietary mount?

It uses a standard 72mm filter thread on the filter side, so any 72mm filter screws in, while the lens side is a standard 67mm thread.
