This Vizelex Cine ND Throttle Lens Mount Adapter from FotodioX allows a Nikon F-mount, G-type lens to be used with a Sony E-mount camera. It is designed to support focusing to infinity and is constructed from brass and aluminum alloy along with a brass mounting ring to provide a durable, yet lightweight camera-to-lens connection.

The Vizelex Cine ND Throttle Lens Mount Adapter includes a built-in variable neutral density filter with an integrated control ring. The variable neutral density filter provides an exposure reduction of 2 to 8 stops so that adjustments to brightness can be made independently of the camera and lens, which enables more flexible exposure and depth-of-field control while recording video within a designated frame rate.

The integrated control ring features a cogwheel design, allowing it to interface with separately available follow-focus accessories.

Q: 1. Can this be used on an old Nikon AI lens that has an aperture ring, such as the Zoom Nikkor ED 50-300mm f4.5?

A: The FotodioX Vizelex Cine ND Throttle Lens Mount Adapter for Nikon F-Mount, G-Type Lens to Micro Four Thirds-Mount Camera can be used with the older AI Zoom-Nikkor 50-300mm f/4.5 ED lens. Though that lens has its own aperture ring to control exposure and it may not makes sense to get an ND throttle adapter. If you do not need the built-in variable neutral density filter in the adapter, it may make more sense to get the FotodioX Mount Adapter for Nikon F-Mount Lens to Micro Four Thirds Camera, BH #FONIKFMFT (https://bhpho.to/3sDpebw).

Q: 2. Will this work with Sony Fx3 with a Canon 24-105mm f4 lense?

A: Yes this adapter would allow the Canon EF 24-105mm f/4L USM lens to work on the Sony FX3.

Q: 3. Can this adapter adjust aperture?

A: Yes. For Nikon F-Mount, G-Type Lens, there is a ring on the adapter that turns to change the lens aperture. It can open or close the aperture, though there is no way of knowing the precise aperture the lens is set to.

Q: 4. Is this supposed to work with Nikkor AI-S lenses? I have been using it with my Nikkor F AI-S 55mm 1.2 lens, and it mounts just fine, but I cannot control aperture at all. Wondering if I have a defective copy, or it's just not compatible with AI-S lenses for aperture control?

A: It is compatible with that lens, but you need to set the aperture directly on the aperture ring on the lens. You won't be able to change aperture on the adapter.

Q: 5. Will this work with Sony NEX5N camera?

A: Yes it is compatible with the NEX5N camera too.

Q: 7. Is there a setting with no ND reduction ?

A: The ND ring would need to be set at the Minimum marking.

Q: 8. Sorry if this is obvious. I have two Nikkor Ai F lenses once used on an F3 - a 35mm f2 and a 50mm f1.8. I also have a Nikon "E" 70-150 zoom. Will this adaptor allow these legacy lenses to be used on the Fuji GFX50R? Thanks.

A: Yes this adapter will work with all of your NIKKOR lenses.

Q: 9. Whats the difference between this vizelex and the Fotodiox Fusion? both same brand, same price.
