Compatible with lenses with 67mm filter threads, this Neewer 67mm Variable ND Filter 1-5 Stopfrom Neewer features a built-in, rotating ring that controls neutral density ranging from 1-5 stops. The variable ND2-ND32 filter allows you to add a sense of movement to an image such as capturing the blur of the rippling water of a waterfall or light trails by affording more control over your shutter speed. With its 9.5mm thickness, this filter also avoids possible vignetting on wide-angle lenses. Constructed with optical glass and an aluminum frame, this lightweight filter's design also has 30 layers of double-sided nano coatings for an anti-oil, anti-dust, anti-scratch, and water-repellent surface that can keep your lens safe.

Q: 10. Can it be used together with other adapters for EF to GFX?

A: Yes, mounting is possible when using more than one adapter.
