The FUJIFILM M Mount Adapter for X-Mount Cameras allows M mount lenses to be used on X mount cameras, such as the FUJIFILM X-Pro1 and X-E1. (Please click on the Specifications tab for lens compatibility.)

The adapter is designed in three parts: an aluminum mount for the body, a stainless steel mount for the lens, and an aluminum central tube. Such a design maintains a 27.8mm distance from the lens mount to the sensor, allowing thus high quality image capture.

On the camera side of the adapter is a group of electronic contacts that automatically pass information to the camera based on pre-registered lens profiles. With firmware version 1.10 or later, this information is transmitted by pressing the Function button on the side of the adapter, which allows users to access the Mount Adapter Settings menu on the rear LCD of the camera.

The Adapter comes with a gauge made of resin for checking the compatibility of M Mount lenses with the adapter. (Some lenses may not be suitable for the adapter even if the gauge indicates them to be compatible.)

The Adapter features an array of signal contacts on the camera end and a Function button on the side of the adapter.

When the camera body recognizes the signal contacts of the Adapter, the "Shoot Without Lens" mode is activated automatically.

Users do not have to go to the MENU screen in order to change this setting, enabling them to start shooting instantly.

Pressing the Function button brings up the Mount Adapter Setting mode instantaneously. This provides ease of operation when registering a new lens to use, entering its settings or changing a lens.

Related Questions and Answers

Q: 1. What is the function of the blue ring? Isn't the aperture ring on the lens used to control aperture?

A: Oops, this blue ring DOES have a function, it is the stop-down ring that allows the FD lens to stop down for metering, or remain open for focusing. FD a lenses are a bit fiddly to mount, but this adapter works better than most.

Q: 2. will this work with a canon 180 macro lens?

A: The FotodioX Canon FD Pro Lens Adapter with Tripod Mount for Fujifilm X-Mount cameras will not work with the Canon 180mm EF Macro lens. To mount this lens to an X-Mount camera, you will need an EF mount to X mount adapter, such as the FotodioX Canon EF Pro Lens Adapter with Built-In Iris Control for Fujifilm X-Mount Cameras: http://bhpho.to/1bsLtCf

Q: 3. This is an interesting, if confusing, lens. I understand that if I try to mount my canon EF 35f2 to the camera, the lens aperture will be stuck wide open to F 2.0. If I use the IRIS control on the adapter wide open, I will still have an effective 2.0 aperture, correct?If I close the IRIS on the adaptor, will my image become sharper, similar to stopping down the EF lens?

A: Yes, iris control on the adapter is the same as aperture control on a lens.

Q: 4. what adapter do I need to attatch a Nikon z adapter to my Fuji xt3? ive been looking for 2 hrs now and cant seem to find where it is

A: If you're looking to adapt Nikon Z mount lenses to a Fuji X mount camera it is not possible. The flange distance (space from the lens mount to the sensor surface) in the Nikon is 16mm and the Fuji is 17.7mm therefore you'd need to mount the Nikon lens inside the camera to have the optics function properly.

Q: 5. I purchased this x mount recently but can not get the shutter to release on my Fujifilm X-T2! I have set everything to manual including front camera dial setting to M and checked all menus to set from AF to manual what am I missing? Appreciate any help from someone who may have experienced same issue, thanks!

A: Please see in menu the option to Release shutter without lens and turn on. This will activate the shutter.

Q: 6. Can I mount an unmodified pre-AI Nikon lens to this adapter without damaging the adapter or camera?

A: you wont be able to change the aperture if you mount it

Q: 7. I want to use this adapter with my XT-2 and Carl Zeiss (ZE) lenses, so I'm ok focusing manually, and I think the built-in iris control should help with the lack of an aperture ring on the lenses, but what kind of disadvantages should I expect by using these three (camera, adapter, lenses) together?

A: the aperture doesn't work - dont bother

Q: 8. is the tripod foot removable from the adapter?

A: Yes, it is!! However the screw hole will be visible.

Q: 9. Can this adapter be used to attach a T/T2 adapter to a 2" focuser of a Sky-Watcher 200PDS and a Fujifilm X-T2?

A: This would allow you to use a T mount with a X-T2.

Q: 10. Does this have a 42mm thread?

A: Yes, the threading on the Vello T-Mount Lens to FUJIFILM X-Mount Camera Lens Adapter measures 42mm.
