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.

This review is of the "Standard" Nikon F to Canon EOS EF adapter sold by Fotodiox. As with any of these adapters the "automatic" lens features are disabled, and with digital cameras the "35mm equivalent" focal length is increased, by about 50% on the camera I have, due to the image sensor being smaller than a 35mm frame. But it allows Nikon-mount lenses to be used on a Canon EOS camera, and while I confirmed some problems noted in the 1-star reviews, this adapter isn't expensive, and the severity of the problems likely varies between examples. The one I got worked for my purpose, which was to attach a lens I had on hand to test a camera body I found "bin-diving" at a local emporium. I am grateful for the reviews noting the "loose screw" issue with the release lever for the Nikon lens. Checking the screw on my example, it not only allowed the lever to move sideways, but was so loose it would soon fall out no matter how it was adjusted. If it had a non-threaded section near the head it would be possible to tighten it leaving the lever free to move, but the makers of this adapter used an ordinary screw and left it loose. The problem can be corrected with a little lacquer or glue on the threads. To avoid gumming up the mechanism I inserted a dab of epoxy through the "back" side of the threaded hole, then adjusted the loose screw for proper operation of the lever, so the end threads would engage the epoxy. The "too tight" problem is a bigger issue. I had no trouble with the fit to the camera, a Canon EOS Digital Rebel DS6041 (300D), though it was tighter than a "T" mount adapter I tried. But the lens was hard to dismount due to the design of the "springs" on the adapter. These are made by spreading a slot cut into the body material and behave more like "wedges." Aluminum does not make a good spring, and the amount the slots are spread does not seem well controlled. It may be possible to adjust the spread for a given lens, but I have just been tolerating the problem. The tight fit can result in side force on the locking pin making it hard to retract, which complicates removal of the lens. For those not concerned with the higher price, the "Pro" version of the adapter appears to have properly designed springs. On the positive side, the adapter seems to position the lens properly so the numbers on the focus scale are about right. It allows infinity focus with the lenses I tried, and maybe even a little "beyond infinity" to cover tolerances. With some minor rework, and checking that it won't get stuck in the camera, the low-cost "Standard" adapter can be very useful, so I'll give it a 3-star "OK" rating despite the noted problems.

My mom gave me a bunch of old Nikon lenses that were in the attic so I thought I'd give this adapter ring a shot since it was only $25-30. It worked well. I was able to hook up 4 different Nikon lenses to my Canon 60D. It takes a little while getting used to the tiny little latch that allows you to take the adapter off the lens but once you understand how it works it's pretty easy. To avoid having to constantly take the adapter off and put it on another lens, I would just recommend buying one adapter for each of your Nikon lenses. You do lose some operational abilities with a Nikon lens hooked up to a Canon camera such as the f/stop dial on the camera body. Not a big deal since I can adjust it on the lens itself. The fact that I was able to add a 60mm Macro and a 70-300mm to my kit for under $30 was worth it. Thanks MOM!

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.
