Q: 1. 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: 2. Can the ND filter be disabled or reduced to a clear setting? Is there a product that can do this?

A: The FotodioX Vizelex Cine ND Throttle Lens Mount Adapter for Canon EF or EF-S-Mount Lens to Select L-Mount Camera has a minimum ND setting of ND2 and does not have a clear setting. We do not carry an EF to L mount adapter with a variable ND built in that has a clear setting at this time.

Q: 3. 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: 4. Is this a smart adapter meaning will it allow continuous af / exchange data between lens and camera body?

Q: 5. Whats the difference between this vizelex and the Fotodiox Fusion? both same brand, same price.

Q: 7. Is this compatible with the Sigma FP?

Q: 8. Can this adapter be used on the new Blackmagic Cinema Camera 6K FF?

A: The FotodioX Vizelex Cine ND Throttle Lens Mount Adapter for Canon EF or EF-S-Mount Lens to Select L-Mount Camera is compatible with the Blackmagic Design Cinema Camera 6K (Leica L).

Q: 9. will this allow me to change f stops on the lens?

A: No, it will not. As stated under the Overview, electronic communication between an attached camera and lens is not supported by this adapter. When removed from a compatible Canon camera, the aperture diaphragm on a Canon EF or EF-S mount lens is designed to open to its widest setting. A Canon EF or EF-S mount lens may be effectively used with its aperture diaphragm fully open along with the Vizelex Pro ND Throttle Lens Mount Adapter. Otherwise, an aperture value on a Canon EF or EF-S mount lens may be set by first placing the lens on a Canon EOS camera and then pressing the camera's depth of field preview button while removing the lens prior to placing it on the adapter. But the adapter does not directly offer aperture adjustment control.

Q: 10. I'd like to use this with my S5 and a Canon EF 16-35mm f/2.8L II - would there likely be vignetting or other image quality issues caused by this adapter? Would I be better off just getting the Lumix Pro 16-35?

A: There isn't vignetting or image quality issues. Main issues are in autofocus that it is usually not as fast and not as reliable. For the best autofocus features it is recommended to get a native Panasonic lens.
