If your M42-mount lens has no aperture pin, tabs, or levers; or if it has an aperture pin that does not fully depress (small tabs stick out), it is considered a type-1 lens and this V1 lens mount adapter is compatible with it.

However, if the aperture pin of your M42-mount lens depresses all the way down, your lens is considered type 2 and is compatible with V2 adapters (available separately).

Related Questions and Answers

Q: 1. 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: 2. is there a setting for zero ND? or is it only ND2 to ND1000(?)

A: No, there isn't any zero ND position of the adjustment ring. Even in the MAX position (max. transparency) you lose some light. Between MIN and MAX you can adjust the transparency fluently.

Q: 3. 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.

Q: 4. Does this adapter have any glass optics?

A: No.

Q: 5. 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: 6. Will this adapter allow my Canon EF lenses to fit the new Olympus OM1 camera ?

A: Yes, FotodioX Vizelex Cine ND Throttle Lens Adapter is design to connect Canon EOS EF lenses to Olympus Micro 4/3 mirrorless cameras

Q: 7. 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: 8. Is this compatible with old Nikkor F-mount lenses, where you manually change the aperture on the lens? I know it would be compatible shooting video, but it is compatible to take photos/stills?

A: Yes it would also be compatible with those older Nikon F mount lenses to take photos/stills.

Q: 9. Some YT reviewers state this ND range starts at 2 stops, not 1 stop. Can anyone confirm?

A: Thanks for bringing this up to our attention. FotodioX Vizelex Cine ND Throttle Lens Mount Adapter for Canon EF or EF-S-Mount Lens to Select L-Mount Camera starts at ND4 (2-stops) and ends at ND256 (8-stops). Our Web Desk Department will correct the error in our website.

Q: 10. So I am able to mount a M42 Lens on a Sony body with this and it will give me ND?

A: The FotodioX Vizelex Cine ND Throttle Lens Mount Double Adapter Kit for M42-Mount Lens to Sony E-Mount Camera allows you to mount both M42 mount lenses and Canon EF/EF-s lenses on a Sony E mount body. It 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.
