Blending features from two of their most appreciated adapters, Fotodiox has designed the FUSION ND Throttle Auto Adapter which allows for electronic communication between the lens and camera and incorporates a 1 to 8.5-stop variable ND filter. This model enables the use of Canon EF-mount lenses with a Sony E-mount mirrorless camera and, thanks to the electronic contacts, users can now control the lens aperture from the camera body as well as work with autofocus, auto exposure, and image stabilization. In addition to all of this, the adapter will transfer Exif data to the camera and it offers a geared control ring for adjusting the density of the filter either by hand or with a follow focus system. Additionally, the adapter is constructed for brass with a stainless steel finish and comes with a removable 1/4"-20 tripod foot.
