Fotodiox Pro Lens Mount Adapter Compatible with Nikon F-Mount Lenses on Canon EOS (EF, EF-S) Mount D/SLR Camera Body

I bought this to replace a cheaper knock-off adapter I got from the "Big Auction Site", so I can directly compare them side-by-side. That cheaper adapter said it would work with Nikon's older non-AI lenses. Well, it did mount on the lens, but the tolerance was so tight you could not turn the aperture ring, making it not particularly useful (unless I suppose you were OK with shooting the lens wide-open). The Fotodiox adapter looks almost exactly the same so clearly the cheaper knock-off copied the design. The only difference is that black ring which can see in the photo. Not quite sure if it is a plastic insert or just some type of paint, but the cheaper knock-off didn't have that. It was just bare metal. The aperture ring of the lens contacts the adapter at that point, so I don't know if that has anything to do with it working correctly or if the Fotodiox is just made to tighter tolerances, but it mounts perfectly and the aperture rings turns as it should. It is also much easier to remove the Fotodiox adapter from the lens than the cheap knock-off is. The Fotodiox adapter is twice the cost of the cheaper knock-off I got, but the reality is that it just works 100% as it should. I suppose you get what you pay for, so I'm sticking with Fotodiox rather than the cheaper knock-off adapters from now on. Overall, I highly recommend it. EDIT to add: I note several previous reviewers indicating that it is difficult to remove the adapter from the lens and I would agree with that. Pushing down the lever and trying to twist the adapter off the lens is difficult because it is a tight fit. It simply requires more "force" than one would expect, but it will actually come off when such force is applied. Frankly, the cheap copy of this adapter I had was even worse in that regard so I would say the Fotodiox is an improvement.

This is truly an amazing product at a more amazing price. If you look around here in the nikon to eos adapters you can find insane prices such as the NOVOFLEX brand, I've used one before when working on a production and I really wasn't that amazed, it actually was harder to take off the lenses than these Fotodiox mounts are. I understand that there is a fear that these have a fragile clasp that actually holds the adapter to the lens and I somewhat agree. I examined it an it really is just a simple flexing piece of metal (about the same thickness as a paperclip) so I am somewhat afraid of an eventual breakdown, but with careful opening (when possible) it will be okay, but I bought two and will probably buy more so that I can just leave the mounts onto the lenses to prevent possible damage to the clasp, and I recommend this as the best option. Now, when I bought the adapter I was reading reviews as to what they will adapter or if there was any sort of issue I would face. Someone said that they won't accurately mount to a 28mm lens or wider and this is incorrect. I mounted it to my 28mm Nikkor lens and there is no issue of any kind, mainly because a Nikon mount is always a Nikon mount no matter the lens and an EOS body is always an EOS body no matter the model. I'll probably end up editing this and uploading a video review of the product. UPDATE: 11-25-2012 The adapters are still in tremendous shape in-spite of me purposely being rough with them, the "hinge" that connects the lens adapter to the lens is still performing like a champ. When I say rough, I mean rough, I've left the adapter loose with a some of my metal quick release plates in my bag and threw that around not a dent. I've done at least in the 1000's of lens changes with these adapters and not a single problem. Now, with that in mind for the metal clasp, I want to explain something that can be annoying about these adapters. They connect to the camera fine, but there is a little bit of "play / shake" that you can notice if you touch the lens independent of the camera body. This is a very minuscule amount of play that won't really effect anything, except for those who work with DSLR Video by manually focusing by the hand only (no follow focus). For shorter lenses the shake is not noticeable on the final video, but with a longer lens (70-200mm) it can be slightly noticeable on the final video. With that small shake in mind, I simply prepare for it, by gently grabbing the lens for focus changes, not a major problem at all.

This adapter suffers from a design flaw. I will get to in a minute which Nikon/EOS adapter to get. When I turn the focusing ring of a manual focus lens, or an autofocus lens functioning as a manual focus, I expect only the ring to move. With the Fotodiox there is excessive play (> 5 deg) between the lens and the adapter. When you turn the focusing ring with a Nikon AUTOfocus lens mounted, the lens will move first with respect to the adapter before the focusing ring does. I don't know about others but to me this is unacceptable. When I turn the focusing ring I expect only the ring to move. With AI-S (manual focus) lenses, the play is a little less (about 2 degrees), but in both cases there is not just rotational play between the lens and adapter which is hugely annoying but will probably not affect the final image, even worse, there is also a tiny bit of play in the angle the optical axis makes with the image plane. This *does* affect image quality as I have verified. Think 'view camera' where the plane of focus is not parallel to the image plane (sensor). At first I couldn't explain the loss of sharpness even with a stellar Nikon lens like the 17-35/2.8 on my 5d, but after some trial and error I pinned it down to misalignment between the focal plane and the sensor. This is simply not acceptable on any lens adapter regardless of cost. Now that we know what the flaw is, what to do? Well, it turns out are two generic Nikon/EOS adapter designs out there. Most importers (Fotodiox included) order these from China and put their own logo on it. I have an adapter *identical* to the Fotodiox that I got from eBay(tons of those out there) except it doesn't have the Fotodiox name. You can tell this design from the presence of a little black spring loaded lever that you press to unattach the lens from the adapter. This is the flawed design and the one to avoid. The other (costs about the same) has a little square tab with a hole in the middle which you push/pull to mount/ unmount the lens from the adapter. I own one of these as well. There is almost zero play with the lens mounted on this. It fits tightly and is a pleasure to focus with. This is the one to get. These are also plentifully available on eBay. Needless to say, my Fotodiox is going back to Amazon.

I purchased the Fotodiox standard Nikon F to Canon EOS adapter (model Nik-EF) because I have a number of older Nikon F lenses and wanted to play with them a bit with my Canon DSLR. While this adapter does work with Nikon F lenses, the fit is very, very tight. I tried it on 4 different lenses, all with the same very tight result. Tightness has the benefit of keeping it secure, but as a result of being so tight, you have to be very careful. And removing the adapter from the lens requires releasing the spring-loaded Nikon locking pin. When doing this, you need to be careful to ensure the release pin is not being stressed while unscrewing the adapter from the lens. You cannot starting twisting the adapter from the back of the lens before fully releasing the pin. The pin release lever is small and somewhat awkward to use. The entire pin release assembly does not strike me as robust and would be easy to damage by over-stressing. There is one review reporting problems with it. It certainly is not as well-built as the pin release button on a Nikon camera. This adapter is best suited for permanent adaptation of a lens rather than being frequently removed and installed on a different lenses. For $20, that could get to be pretty expensive. And, of course, you do not get any automatic functions. This is strictly for manual picture-taking. I would probably only invest the $20 for a very special Nikon lens and plan on leaving it permanently attached. Update 1: The one Nikon-F lens I have tried is a Micro-Nikkor 55mm f3.5 lens which normally focuses up to about 9.5". It is a very good lens for close-up work. The mechanical fit of this adapter is fine and using the Canon in manual mode is pretty easy. With the Canon, this lens focuses down to about 4" from the subject instead of 9.5". Unfortunately, this also means the infinity focus is fuzzy. This really is not the fault of the adapter, just a partial incompatibility between the lens and the camera. If you shoot at f32, the fuzziness is obviously less. At a wide open f3.5, my guesstimate is you can get sharp focus if you are not more than about 15' from the subject. So, this will still work as a good close-up lens, but that is it. Update 2: I also tried the Canon - M42 Type 2 adapter, which was just delivered. It is much easier to use than the Nikon F. I had some older Pentax-type screw on lenses from a Mamiya camera. These lens worked fine at infinity. The type 2 adapter is for lens with a diaphragm stop down pin on the rear. Again, there are no auto functions, so everything is in manual mode. I tried 35mm, 55mm, and 135mm lenses with the adapter. Of the three, I think the 135mm is the one I would likely use with the Canon camera. No reason to buy the pro model and from everything I have read, programming the focus chip is just too much effort and really is not necessary. Focusing through the viewfinder or screen is sufficient.

I've purchased several adapters from Fotodiox. All of them have been excellent. I have several of these for my Nikon lenses and I am very satisfied with the performance. Admittedly, the tolerances are tight and you'll have to use some force to click the adapter into place on your lens. I'd highly recommend that you then leave it on the lens and buy additional units for your other lenses. The advantage to doing this is simple: less wear and tear on your lens and easier lens changes. The only issue I've had with this adapter is with a third party zoom lens; the adapter causes the aperture ring to be extremely difficult to turn. The solution was to use a cheaper adapter with looser tolerances just for this lens. Now the ring turns freely, but there is a little bit of play between the lens and the adapter (not enough for light loss, but it's there). In short, these are great adapters at a value price that are best left on each lens semi-permanently. Other reviewers' experiences notwithstanding, I've never had any difficulty removing them from my lens. You just have to push down the tab on the back to disengage the pin and apply some torque to overcome the friction. I suspect some reviewers may have either neglected to push the tab down or were turning the adapter in the wrong direction.

I have a Canon 5D and a Nikkor-S Auto 50mm f1.4 lens. On the first attempt of mounting the lens to my 5D, the mount became stuck on the lens. But I managed to get it unstuck. Basically you have to break off a piece of the black tab (shown in the product photo) to be able to fully disengage the pin on the mount from the pin insert on the lens. Why do you have to break the tab? For general function, to fully disengage the pin on the mount, you have to push down on the tab. But the flange (one of the three metal lips on the back of the lens) is in the way of the tab, and you can't completely push down on it. What a flaw! So I broke off part of the tab with some needle-nose pliers, and used tweasers and a flathead screwdriver to coax the pin completely out. Success! I can still use the mount. I just have to screw it on in a way that keeps the pin on the mount from engaging in the pin insert area of the lens. Obviously, that means the lens won't be 100% secure on the lens, but if you screw the lens on tightly, the fit is pretty snug and safe. JUST DON'T SCREW IT ON TOO TIGHTLY, which I think should be a general rule for anything camera related (I work as a camera assistant, and I can't tell you how many times I get so annoyed with dudes who overcrank on mounting a lens to a camera...gentle yet firm touches, guys). Anyway, feel free to buy this mount...it's decently priced. BUT JUST BE CAREFUL!

After seeing some of the mixed reviews, I was a tad bit hesitant to purchase this inexpensive adapter. I'm glad I took the plunge! The two lenses I am using are old Nikon non-AI type lenses. One is a Nikkor-S 50mm f/1.4, the other is a Soligor 400mm f/6.3 (often sold under different names as well). It works absolutely fine on both lenses, and fits nice and tight. No wiggle/wobble present when the lens is all mounted up. The tricky part is removing the adapter, but in reality it is VERY EASY! When you take the lens off of the camera, there is a black tab on the rear of the adapter. Simply press the tab down and turn the adapter clockwise (you may have to press and hold the tab while twisting the adapter off initially). It may be a tad bit stiff, but it does come off with relative ease.

The EOS side of the adapter locks into my 5D as smooth and snug as any Canon lens I own. The only issue I had was that the Nikon side was a bit loose when attached to the Nikkors I tried. After a quick Internet search, I found the answer...the Nikon side is adjustable! If you look closely at the 3 flanges that hook into the lens, there is a seam along the edge. I gently wedged a knife into this seam to make the flanges thicker. Now the adapter fits the lens nice and tight. Be careful though...it is an extremely minor adjustment. It doesn't look like the flange thickness changed, but it definitely did. It seems that not everyone has this problem of the lens fitting loosely on the adapter. My guess is that each adapter is slightly different. If yours fits your lens right out of the box, great. If it's a bit loose though, try this simple adjustment. I plan on leaving the adapter on the lens, and purchasing more adapters for my other Nikkors. I don't trust this adapter to hold up well if it is removed and remounted multiple times.

as stated in the headline, the one I got is too tight on the lens side and made it almost impossible to remove.. I even have to wear glove to add more friction. the camera side is the opposite and I can even see the lens is lightly sagging. I returned it back to Amazon in the end, and would not recommend this (Nikon F to Canon EOS) to anyone.

Great deal for the cost. Perfect if you were like me and had an old Nikon lens from a film slr camera with manual aperture control on the lens. Lets me use it perfectly with my rebel T3i. Things to note: you will not be able to use auto focus with this, Also only by if you have lens with manual aperture control because you will not be able to change aperture through the camera.

Ce produit marche parfaitement pour mettre mes objectifs Nikkor sur mon boîtier Canon Eos30D, et ça a l'air solide. Je recommande.

Well made, actually used it to connect to another adapter which also happened to be Fotodiox, and glad I bought this one, although I hadn’t realised at the time, as it mates perfectly

Comme attendu. Parfait.
