The FotodioX Macro Focusing Helicoid allows a Nikon G or DX lens to be used as macro lens with variable magnification ability on a Nikon DSLR camera body. It features a leaf spring design to hold the lens tightly to the camera body, ensuring there is no play between the camera and the lens. In addition, the helicoid features an all metal design and a polished surface for smooth mounting. Although the lens will fit physically, automatic diaphragm, auto-focusing, and other functions will not operate correctly while using this adapter. In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera. You can shoot with manual mode or aperture priority mode.

Related Questions and Answers

Q: 1. Given that there are no electrical connections passed between body and lens, couldn't it also be used on film SLRs?

A: Yes, you can mount the FotodioX Macro Focusing Helicoid (Nikon G & DX Lenses to Nikon DSLR Body) on SLR camera bodies.

Q: 2. Can I use the z mount 105 micro lens with this bellows?

A: Yes, you can use the FotodioX Macro Bellows for Nikon Z with the Nikon NIKKOR Z MC 105mm f/2.8 VR S.

Q: 3. How much extension can this helicoid provide?

A: The extension provided by the FotodioX Macro Focusing Helicoid (Nikon G & DX Lenses to Nikon DSLR Body) is approximately 3".

Q: 4. Two questions: 1) is it necessary to use a lens designated as macro with this bellows and 2) if using a lens without a manual aperture ring (Nikon), it will stay wide open, is that right?

A: Question 1, no you don't need to use a macro specific lens with the bellows. Question 2, the bellows unit doesn't any sensors on it to connect with your camera, meaning everything is going to be manual. The rails on the unit do get in the way at times if you plan on using a ring flash.

Q: 5. Does this maintain correct infinity focus?

A: Once the helicoid is adjusted from its original position, infinity focus will no longer be available. When the adapter is in its original position, the infinity focus function will work.

Q: 6. The person who left a review for this product said he could not connect his 105mm macro, what is the reason for this ?

A: This is old school macro. I would not use this with a macro (micro in Nikon terms) lens. It is intended to be used with a fixed focus standard lens such as 50mm for example. Nikon used to make these before they started making dedicated micro lenses. The bellows allows for the standard lens to be run further out from the film (sic) plane and thus magnify the image. All coupling to the body will be lost thus electronic diaphragms are disconnected. All lenses that precede the G series should be OK because you can manually set the aperture. I suspect setting exposure entails some Kentucky windage along with trial and error. G series lenses would have to be set based on a wide open aperture and just live with the reduced depth of field.

Q: 7. Will the FTZ adapter work on this?

A: You could mount Nikon F lenses on the FotodioX Macro Bellows for Nikon Z with the Nikon FTZ adapter. When the lens is on the bellows there is no communication between the camera and the lens. So it is best to use lenses with an aperture ring.

Q: 8. Will this lens adapter enable autofocusing with Nikkor D type lenses?

A: This lens adapter is manual focus only.

Q: 9. How is the aperture controlled?

A: The following unit is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted. 'Focus-By-Wire' lenses (such as Canon's STM or Nikons AF-P) requires power to engage the manual focus rings on the lens, since manual lens mount adapters do not power the lens, those lenses will not be able to focus. Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode. If your lens does not have a manual aperture control ring, the lens aperture will revert to its default position, which depending on the lens is either stopped down to its largest f-stop or opened up to its smallest f-stop.

Q: 10. What is the weight of this item, and what are its dimensions?

A: 70mm diameter x 20mm thick and weighs about 8oz.
