Fotodiox’s new ND Throttle allows you to adapt medium format lenses to Canon and Nikon DSLRs. It also includes a built-in variable ND filter, which allows you to use a variable ND filter on even wide-angle lenses.
The variable ND filter inside the ND Throttle adapter gives you a range from ND 2 to ND 1000. It is available for Pentax 645, Mamiya 645 and Hasselblad V lens systems. DSLR mounts include Canon EOS and Nikon F mount systems.[youtube https://www.youtube.com/watch?v=VI0tylz6AKA&w=700]
