Fotodiox Lens Mount Adapter, Canon EOS Lens to Samsung NX-Series Camera, fits Samsung NX5, NX10, NX11, NX20, NX100, NX200, NX210, NX1000, fits EOS EF, and EF-S Lenses

This is a straightforward billet adapter so you can essentially leave the tiny ecosystem of Samsung only lenses. This way I can share lenses with my Vivitar 220/sl. Be aware you have an APS-C sensor and it will have some amount of crop factor with the lenses adapted.It works as well as an adapter that has to hold down a button can. Make sure your camera is in manual (M) mode otherwise it'll put up errors instead of taking the shot.

Put this adaptor on my Samsung NX100, I got "no lens" error. It turned out that the flange on the adaptor is not designed properly to depress the indicator on the camera body. It is very strange that there is a small gap in the adaptor flange, which is the exact location to depress the indicator. Because of this small gap (about 1mm), there is no way to depress the indicator. As as result, the camera body thinks there is no lens attached.The adaptor is all metal construction, feel well built. But it doesn't work for Samsung nx100...[update @ Sept 24, 2012]I decide to fix this problem myself (instead of return the adaptor) since there is no much options for this kind of Nikon->Nx adaptor. It is a relative simple fix if you know how to use JB Weld. I use JB weld to apply a patch for that small gap, and let it dry for 24 hours, and it works. Now Samsung nx100 recognize the adaptor, no more "no lens" error.

So, first off let me say that all the reviews about this item being difficult to dismount from the camera or lens are bogus. Even in the product image you can see that there is a slider for the release and though it may not be obvious that this slides to release rather that a press release it is not difficult to make the leap.I give the product a 4/5 insdead of a 5/5 because the release does seem slightly weaker than it should, and while the rest of the product is great overall this release may wear out with time and snap off. However, it is light enough that if this does happen you will be able to reasonably work the adapter off the camera without too much trouble. But I would like to see a stronger pin for that release...Now to the good stuff! Samsung lovers now have an excellent option for telephoto zoom!While the cons are minimal at this point, I believe they will improve with time should the Samsung owners be provided with an adapter that can communicate to the Canon lenses for autofocus and OIS. But, I cannot complain about having this current option for telephoto zoom as Samsung have abstained from a full-blown telephoto lens for their NX line (or any line for that matter). And, considering the price of the Samsung 50-150 you will likely spend a pretty penny for that telephoto when it arrives!Okay, so back to the cons: cannot use in Auto Mode. All other modes are operable but Auto Mode will send a lens error as the camera cannot communicate with the lens. As mentioned earlier, I hope Fotodiox or someone else takes the lead and resolves this issue with an adapter that can translate. Without this communication you cannot use autofocus or OIS, so newbies might as well forget about it. But, if you can control your dials you will have fun with this one. Note: if you are good with your equipment you can get a clearer picture without OIS anyway, with or without a tripod, so if you are able to do that already the only thing you will need to learn is how to get used to physically controlling a sizable telephoto like this.However, the pros are huge. As said, if you can control your dials, then you will have an excellent telephoto. I have read that in order to control your f-stop you may need to plug the lens onto a Canon, adjust the aperture, and then remount the lens to your NX1. However, as you may have noticed with your Samsung lenses the f-stops adjust with the zoom anyway, so even if you change this it likely won't stay at that stop throughout the zoom.More to come, as today I am testing in daylight settings, but the lowlight shots I took last night are without a doubt acceptable.

Does the job; works great. I have a Fed rangefinder (basically, a Leica made by Russians, who stole the designs from Germany during WWII). The adapter was a bit snug, but it seems to work fine. The lens is now living on the camera (NX300), and works great.I almost took off a star because the blue metal looks stupid. Frankly, I can't find another adapter of this kind anywhere, and this thing has really bought a new lease on life for my rangefinder lens. Five stars it is, then.P.S. If you have a Leica lens, or even just one of its Russian FED cousins, you OWE it to yourself to get this! Mirrorless/system cameras are basically the same form-factor as rangefinders; because they don't need to focus through a mirror box (like a SLR/dSLR has to), the lenses are sharper, smaller, and lighter. Also, I can't find a Zeiss lens in NX to save my life, so this adapter is probably the easiest way to get a premium lens onto your NX system camera.

This adapter is quite heavy duty. This adapter is to connect a canon EF lens to the Samsung NX mount. It is a dumb adapter meaning that auto focus and aperture capabilities are out of the question. Luckily it has a smooth aperture ring that allows you to change the aperture on the go without the clicks. It's perfect for videographers. The downside is that well there is no autofocus, though you really can't blame the adapter. Though without image stabilization or a tripod this adapter will only do photos, because any video will be shaky because of the lack of stabilization. Another feature I liked is having the ability to close the aperture before removing the lens, this way I protect the sensor from any dirt or dust, especially because there is no mirror to protect the sensor. The biggest issue I had with this adapter is how tight it is. Regular canon lenses are snug with the adapter, but L-lenses with their rubber gaskets are another story. L-lenses are pretty difficult to remove keep that in mind. Also, canon lenses are typically heavier than most NX mount cameras, leaving the camera off balance and leaning forward.
