Fotodiox Lens Mount Adapter - Nikon Nikkor F Mount D/SLR Lens to Canon EOS (EF, EF-S) Mount SLR Camera Body

I'm glad this adapter wasn't very much money. Although it works perfectly, just as designed, what I discovered was I don't like going backwards and manually focusing any more. Thought it would be cool to try my old lenses on my newer Canon, well, it wasn't. It was a pain. I don't care what a lot of YouTubers say, the quality in the old lenses just isn't up to the quality of the newer ones. And these old hands and old eyes are just not good at focusing any longer. How did I manage to get all those great pictures all those years ago? At least the lesson learned didn't cost too much.

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.

I bought this adapter on the advice that it was a serious, superior product. It sure is. I had to put this to through the test in a unique way. I needed to adapt a 600mm Asanuma lens to a Canon EOS frame. Then the entire rig had to be incorporated into an experimental dual mount astronomical drive system to photograph the total eclipse up in Page, Arizona. There would be no room for error as the window for the eclipse was 4 minutes and 14 seconds. The idea was to take 399 sequential pictures to later turn into a time lapse film of the event. This mount couldn't suffer from light leaks, inaccurate machining, poor threading, lack of robustness, etc. The lens weighed in at a substantial amount. At site everything went together perfectly, and when the time came everything went off smoothly with no hitches. I would recommend this adapter for any situation, period. It works flawlessly and is of the highest grade. BTW that Asanuma lens is a fantastic lens (don't believe anyone writing on it that has an opinion and isn't familiar with the lens or its history). If you don't want to spend thousands of dollars for a 'new' supertelephoto lens but want to have FUN with one by all means find one of these or any of the other pre-digital lenses that can T-adapt. You can even pick up a questar telephoto if you look for them and I'll tell you this- NOTHING EVER made in the telephoto market can compete with the optics of a Questar telephoto- then and now. This adapter opens up a whole world of possibilities by making these legacy lenses once more relevant. You can now afford a boatload of them and use a single adapter to incorporate them on your camera. So you need to use it in manual mode- big deal. You should know how to do that anyways. I'll be getting more of these for my other lenses I'll be adapting to the Canon EOS frame. Best piece of equipment ever!

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've been using these for a while on a set of Nikkor primes I have for my 60D. Works great, a lot of people say that the release mechanism is flimsy but I don't think it's bad. Maybe I've got newer ones but they're metal peices and seem pretty sturdy. That being said, I have an adapter for each lens and never take them off. There is some play in the adapter, not where the adapter mounts to the Canon body but where the Nikkor lens mounts to the adapter. For video it is an unusable amount of play. When doing any sort of focus pulling it shifts and also makes a light noise. For photos it's not a problem, however I use my camera for 90% video, and have these lenses especially for video. I get around this by using some red electrical tape that I cut to the right size and apply on the Nikkor lens mount where it makes contact with the adapter. The play in the adapter is not front to back but rather side to side, so the tape needs to be applied to the side of the Nikkor lens mount between the part that hooks into the adapter and the base of the lens (obviously on the side facing outwards that contacts the adapter, parallel to the aperture ring). Sometimes there is so much play that two pieces of tape are needed. In this case it is important that the top piece completely overlaps the bottom piece to allow the lens mount to slide smoothly over the tape. Each adapter I find has play in a slightly different area, so apply to the three mounting points as necessary. I like to use red electrical tape for this as it is easily visible should the tape become damaged when mounting, however vinyl electrical tape tends to stick together or stretch rather than break off in small pieces so I have never had this happen. Once the lens is mounted to the adapter without play I never remove the adapter and it works great. Almost better than the new L series Canons as their focus wheel is not a direct connection and develops play with time, especially under heavy manual focus use during video. Would have given 5 stars if not for the play.

I had low expectations about this product, because, really, how well should a 30 year old lens perform on one of today's cameras? Add another piece of glass in between, and the odds skyrocket. Incredibly, I was proven wrong. The only lens I've tried with the adapter so far was a Minolta MC 50mm 1.8 Prime. On my old SRT101, the lens creates beautiful depth-of-field and soft edges, like an old 35mm should. I hoped these points would carry over, and they're already proving to do so. The colors are bright, and the images can be made crisp by centering the light meter, or if overexposing, the 60d recreates the soft ethereal edges and deep contrasts in low lighting. I am still fine-tuning the images, because often times there is a lot of noise, as oft times occurs with slow/manual lenses and incorrect balancing. The glass is well made with no flaws (and I looked hard for one), and there is little distortion when you're putting enough light through it. Because the adapter itself is just over 1cm thick, the 60d frames closer to an 85mm prime than a 50mm. I suspect this will be the case with my 135mm 2.8 as well, and the only complaint I have for this cheap and effective adapter is that there is a little bit of "drunkenness" in the background blur when the lower two f-stops are used (1.8 and 2). It is almost like looking at a 3d image without glasses. The only time this happens is with close backgrounds in close focus, and shooting into the light. One could easily correct this with a gaussian blur in a photo editor. The adapter seats firmly to the body, as does the lens. There is no secure "click" lock for either body or lens, but the adapter does have a push-button lock for the body-to-adapter. Overall, a great price for a simple (but well-made) tool for recapturing the textures of your favorite old lenses.

I bought this adapter to use with an Olympus G. Zuiko 55mm f/1.2 lens but it was too tight and it did not fit (I tried to mount it firmly but did not want to risk breaking by forcing too much). I found out that the little bumps in the adapter (which normally ensure a tight fit) were too big. After hammering them down a bit, the adapter can be mounted on the lens but after clicking in place it has a bit of play (not sure if it is the result of hammering down the bumps since it is still quite tight when mounting, it feels loose only at the final position after the click). It is annoying, but it's usable at least. Otherwise it's OK, the material seems durable and the camera side of the adapter fits well on both of my EF-RF adapters (one is a simple adapter, the other is a focal reducer). Overall, I'm glad I can finally use this old lens on my digital camera, but would be happier with a more precisely made adapter (before this I had another no-name one, which did not fit as well and I couldn't even make it work). Also because this slight looseness I don't recommend using it with larger, heavier lenses.

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.
