If you have a SLR or DSLR camera and other maker/mount lenses, the Fotodiox Mount Adapters allow you to use your lenses on the film/digital camera body. Sharing lenses has some distinct advantages. Certain prime lens just can't be replaced, and you save the cost of purchase on new lenses. Fotodiox offers a range of adapter from large format to smaller format digital adapters. Adapting larger format lens to smaller format sensors (i.e: large format to medium format, medium format to 35mm, 35mm to micro 4/3) provides excellent edge-to-edge sharpness. The smaller image field helps minimize the effects of lens distortion and aberration by using the 'sweet spot' or center of the larger lens image circle.

This is one of the Pro-series lens mount adapter made with precision and pristine award standard. As all Pro-series adapters, these adapters have been specially crafted to endure professional lenses. No "play" between lens and Camera. With unique styling, the lens mount adapter maintains/enhances professional appearance. The all metal design and polished surface is designed to guarantee smooth mounting and long lasting experiences. This adapter allows Contarex CRX-Mount Lenses to fit on Fujifilm X-Mount camera bodies.

Although the lens will fit physically, automatic diaphragm, auto-focusing, or any 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 body. You can shoot with manual mode or aperture priority mode. Infinity focusing is guaranteed.

Compatible Cameras (Including, but not limited to):
Fuji X-Pro1, X-E1, X-M1, X-A1, X-E2, X-T1

This is potentially an OK adapter made terrible by no instructions.

Like many here I got my adapter stuck on my lens, panicked, and thought my expensive lens was ruined. The reason, NO INSTRUCTIONS AS TO HOW TO REMOVE THE ADAPTER. I had to go to a youtube video to discover I needed to SLIDE THE SILVER BUTTON BACK, NOT PRESS IT. How expensive would it have been to include a small instruction booklet???

Another pain point, IF YOUR LENS HAS NO APERTURE RING THIS ADAPTER IS NOT FOR YOU. There, I said, how hard was that?? Why on Earth Fotodiox doesn't include these basic instructions is beyond me.

Finally for those of you who do have a Nikon lens with an aperture adjusting ring, and now that you have the instructions needed to remove the adapter, I would say this adapter is decent I guess.

Wow! When I received the Fotodiox Nikon to Fuji-X adapter, I was first amazed at the build quality, the weight and solid construction of this adapter. I thought that I would sell off all of my Nikkor lenses with the purchase of my Fujifilm X-T3, but after mounting some of my favorites Nikkor lenses to this adapter and then the X-T3 body, I've decided to keep at least a half-dozen of my favorite lenses. In manual mode on the X-T3 and focus assist, my Nikon lenses perform just as well (sans the AF and AE meter coupling) but with all of the controls that the X-T3 has, it's very easy to use the Nikon glass to it's fullest potential. Fuji makes some excellent lens as well, and until I can afford the Fuji 200mm f2.0, I'll use the Fotodiox mount with my Nikon glass.

All comments pertain to the Nikon-to-Fuji X-mount version. The adapter does exactly what it is said to do -- allow use of Nikon M mount lenses on a Fuji X series body. Note this version will NOT work with G-series Nikon lenses. Those are the ones without an aperture setting ring; there is a different version available for those. Both the camera-adapter fit and the adapter-lens fit were good. Easy to mount and to remove. Everything felt secure with no wiggle. That sums up about all that is claimed.

For those not familiar with the product:
There is NO autofocus. There is NO aperture control between the body and the lens.
Despite the above, taking photos is actually pretty easy. The first step is to go into the Fuji menu and select "Shoot Without Lens" and set it to "ON".

Exposure - You can either set the camera to manual exposure and use it just like you were using a Fuji lens. Or you can set the shutter speed dial to "A" and use it like "aperture priority". You loose some information that is normally in the viewfinder but the exposure aspect of shooting is otherwise pretty much like you get with a Fuji lens but without shutter priority.

Focus - Manual focus only. If you are using a Nikon wide angle using the distance markings next to aperture ring may be all you need. I don't find my purely visual focus very accurate - you may. A better way to use focus peaking. (On my X-E1 you need to update to the latest firmware and be sure the focus mode is set to M.) Try this on your Fuji before your buy the adapter to be sure you and focus successfully. If you find this doesn't work for you using a Fuji lens there is no value to buying the adapter. (PS: I find manual focus of a Nikon lens on the Fuji is easier than manual focus on a Nikon body!)

Why would one want to use a Nikon lens on a Fuji X?
A- you own one or more Nikon lenses and you are just naturally frugal.
B- You are not fully committed to moving to mirrorless body and don't want to commit buy buying a bunch of lenses yet.
C-There are certain capabilities the Fuji lens line up lacks: 1:1 macro, exotic features like the Nikon's DC lenses or tilt/shift lenses.
D- you have some non-AF Nikon lenses (Ai-S) and focus peaking manual focus works better than what your Nikon body offers.

Much of this probably applies to other mounts such as Canon, M42 etc as well as to Nikon
B- you are making the transition to mirrorless but are not sure yet

Easy and inexpensive way to get old Nikon F-mount glass to work with my Fuji XT-1. Its solid metal and feels well built and sturdy. Because of the very tight fit which ensures no light leaks and proper focusing capability, I would highly recommend that this adapter stays on whatever lens you put it on to avoid damage especially if you have made the complete leap to Fuji X.

Note the little side locking knob may be a little tough to budge the first time. Mine was anyway and it seems other reviewers had the same problem. I had to take a small pair of pliers to pop it from its stuck position. You need to hear a click to ensure its locked. If you don't hear it, don't let go of the lens until you get the side knob unstuck. Once I got the knob to slide up and down properly, everything has been fine since.

Just remember, this will neither pass any information to the camera nor receive any information from the camera. This means auto-focus and auto-aperture won't work. Your lens will be a complete manual lens. It also means lens information like aperture or focal length will not be recorded in the image's metadata. If you want that information, you'll have to do it the old fashioned way by taking notes and manually inputting the information with your post-processing software. I'd definitely recommend this to expand your Fuji X lens selection and to be able to continue using some of your favorite glass.

Well made and a good fit. Be aware that this is a "Type 2" Fotodiox adapter, which means it has a flange behind the silver part which is designed to depress the auto locking pin on those M42 lenses that don't have an auto/manual switch. This made no difference to any of my M42 lenses, including 55mm and 35mm Pentax Takumars, until I tried a 50mm 1.4 Super-Multi-Coated Takumar. That lens has a wider tab which fouls the flange.

The good news is that you can remove the flange (at least you can on mine), by unscrewing the three allen bolts that are there to adjust the angle of the mounted lens, removing the silver threaded mount, and then you can remove the black ring which forms the flange.

The bad news is that this then leaves the back of the threaded silver part visible from inside the mount, which means it may reflect and cause loss of contrast.

I could probably have played around with filing the ring down or painting the mount black, but I've opted to get hold of another mount without the flange (unfortunately, Fotodiox don't seem to sell the Type 1 anymore) just for the 50/1.4 Tak, and put the flange back on this for everything else.

The Fotodiox Nikon to Fuji lens adapter allows Nikon lenses with aperture rings, to fit to Fuji's X system cameras (there is a different adapter or Nikon 'G' lenses). The reason I went for the more basic adapter is because I have plenty of older lenses and my newer Nikon lenses tend to be zooms, which are much bigger and heavier, so not really ideal for mounting on an X-E1.

The basic idea is that by adding the adapter, you increase the flange distance between the camera and the lens and add system adapter to the camera (in this case the Nikon F mount). The system is really basic and works well. Everything works manually and you have to set the camera to work without lenses, as there are not contact points between the camera and adapter. Aperture is handled through lens and you have to manual focus (which isn't to hard, even at low apertures, with the X-E1 zoom and focus peaking ability).

The build of the adapter is very good, it took me a few minutes to work out how to remove the lens (there is a round button, which I tried to push and pull (in fact you need to slide back to open the lens lock). I would suggest, that Fotodiox create a small video showing how unmount lens process and put it on their site.

I have a small problem with importing the product Fotodiox were very good and refunded the extra money I had to pay very promptly after I raised the issue with them.

All in all I am very pleased with the adapter.

This works really easily and I'm delighted with the look of the Leica lenses on the XT-2. I also have the fujinon M adapter but for some reason this has a problem with focusing in the10m to infinity range on my 35mm lens (though it works fine on the 90mm) - I have to look into this. Happily no problems with the Fotodiox so I'd recommend it. I also like to have an adapter on each lens rather than having to swap the adapter every time you change lens ...the Fotodiox is reasonably priced.

Ordered on Tuesday, delivered on Wednesday on a free delivery option!

Great lens mount adapter, a bit dubious as not a major 'brand name' from my knowledge but a great, well made and quality finished adapter (could have been made by Fuji) i.e. it doesn't look cheap).

Allows me to mount manual Minolta lenses to my Fuji XT-2. Quality and appearance blends in well with the camera finish and doesn't look out of place, nor does it affect the handling of the camera/50mm lens combo.

Happy purchase so far......

Bought this adapter so I could fit some of my vintage Pentax lenses to my Fuji X-T2. The lenses snapped into place firmly with no wiggle, which for a "dumb" manual lens adapter is the most important thing. Finish is good and construction sturdy. I've already added the manufacturer's Nikon F mount adapter to my wish list.

Bought this adapter to use my Nikon 50 1.4d & 1.2ais lenses on my XE1.

The adapter is well made and solid, it mounts quite tightly to my Nikon lenses but is an easier fit to the camera; it has no slop or play when is use. It is discrete and when mounted with a lens it looks good and does not look out of place.

When using my Nikon 50 1.2ais the camera feels unbalanced and not pleasant to use because there is a lot of glass and metal in the 1.2ais and the adapter moves the lens further away from the camera, the 50 1.4d is lighter and easier to handle on the camera - although, still slightly unbalanced. Both lenses have aperture rings, smooth focus rings and work fine on the XE1; if you intend to use Nikon G type lenses with this adapter they will not work properly because you lose aperture control.

The adapter looses a star for a couple of small machining marks and the lever to remove your lens is quite stiff and is not smooth.

Overall, the adapter is good value for money and generally well made.

The worst ever product & customer support I've ever experienced.
I bought 4 lens mount from this seller as I read a couple of positive review on the internet.

1. M42 to EOS & M42 to Fuji adapter
Altough they are advertised to support infinity focus, they do not in fact.
When I focus to infinity everything is out of focus.
I had to reverse focus ring to make it focused.
But I did not take this as a serious problem as it seems too minor issue

2. C/Y to EOS & C/Y to Fuji adapter
They had much worse problem.
C/Y to EOS did not work properly with Canon 5D Mark II.
With focused to infinity, the mirror was stuck open after sutter release.
I tried Canon 7D as well sometimes had no issue sometimes had same issue
I also found light leak using C/Y to Fuji adapter. The light came through where lens release button located.
So I contacted the seller and explained these issues.
They told me to return the item and I sent back the item.
No response for long time. I contacted again but they said the item not delivered yet.
But I knew the item already delivered as I had tracking number.
Contacted again and they said the item was under inspection this time.
Another 10 days or so replacement for C/Y to EOS was delivered without any notice.
However the replacement had same issue and I asked for refund for C/Y to Fuji adapter including return postage
Here is their reply.
"Hello We did check the adapter when it arrived back here, and found that it was not a flawed item. That is why the refund department did not refund you shipping in either direction. As a courtesy to you I will refund the shipping to the point of what we charged you to ship, and use that amount to refund a portion of the return shipping."
They are GENEROUS enough to give me a courtesy of £3.48 in fact return postage costed me £18.55 as they are in US
This is summary of what I experienced with this seller so please avoid this seller.

Used for adapting Nikkor lenses to Fuji XE2 camera. Works well for old lenses with aperture rings, and newer G style without. Seems to be well made, no rattles or shakes, and lenses have no play once attached, snug fit. There are 5 (uncalibrated) aperture positions marked on the blue ring, going from wide open to fully closed - but you have to work out what these mean in real f/No terms by metering with your lens. Blue aperture ring is flush with rest of adapter body, so not easy to change aperture just by touch - maybe with practice it will get better.
No instructions supplied - why would you need them? Except there is a strange additional lever next to the blue ring with 2 positions - but I cannot figure out what this is meant to do.

Great quality, very solid and appears to be all metal construction. Smoothly attaches and detaches from my Fuji X-E2. Does a brilliant job of resurrecting my old Nikon fit full frame (i.e film) lenses. Very happy with the results.

I have a Fuji X mount camera want to fit various Nikon, Canon, Vivitar, Sigma lenses. Needed a good quality Tripod mountable adapter that can take weight of 400mm f5.6 Sigma-2+kilos- all up. This works well, canon type was more expensive than other fittings however saved a lot of trouble with 3rd party lens tripod fittings.

The Fotodiox adapter is a good bit slimmer than the bulky K&F adapter and the internal surfaces are proper matt black paint. Good fit on my Fuji X-T2 It weighs 99g - as much as some lenses but less than the K&F Concept. It's a shame that neither of these adapters come with a rear lens cap - which you're definitely going to need.

Does exactly what it says it will. feels good quality. Took me a moment to realise you pull the button to release the lens down not press it in - doh!

It is more expensive than some but it feels well made compared to others I have bought for other conversions.

Delivery was fantastic given it was supposed to come from the US. You can also get pre sales help. I asked a question about a different adapter and got a very intelligent reply.

This item is made of two distinct adapter. The shift part is a Fujifilm X to Canon EOS, the other one is a Canon EOS to Zenza Bronica PG. Being a EOS mount coupled with another adapter it can mount Nikon and Pentax glass without losing focus to infinity. With a full frame lens it should give a little more than 7mm of shift in every direction, but some lenses can give you more. The shift mechanism is well damped but still heavy lens tend to drop down when unlocked. The rotation is a little ankward to use at first and sometimes don't lock firmly in place. The Eos to bronica adapter have a tripod mount (missing on the shift adapter). In the end is a good tool who work as intended as a cheap alternative to true shift lenses.

this adapter fits the camera i bought it for so I can use my old lens' but the photo shutter absolutely refuses to function. So as a lens adaapter it makes an excellant, very expensive paper weight! Am i missing any dark arcane secrets of lens craft and photographic art?

Not up to the engineering standard of top brands but Fotodiox offers great value for money for a perfectly adequate product. recommended.
