Fotodiox Lens Mount Adapter - Compatible with Canon FD & FL 35mm SLR Lenses to Sony Alpha E-Mount Mirrorless Cameras

I bought this adapter because I needed more versatility out of my Alpha Nex 5, as I only had the 16mm lens. I didn't want to drop $300 for the 18-55 lens, especially with the amount of barrel distortion it has. So with already having a couple FD lenses, I was keen on buying this adapter. I must say, it was an excellent purchase! I was warned that it might degrade image quality if I use a mount, but my pictures look better than ever. This is everything you could ever want out of a mount, it's small, allows for breach and bayonet mounting (I have both, and have tested both to work incredibly), and even aperture control (make sure to mount the lens correctly though otherwise you will not have this feature)! This adapter specifically is incredible because of the price you can get FD lenses. I have a Vivitar 28-200 macro, a Vivitar 500mm Mirror lens, a Canon 50mm prime, and a Canon 70-150mm zoom lens (picked them up for about a total of $45, look around Goodwill and garage sales for incredible deals on these lenses). The types of pictures I can now take are incredibly diverse, and all at the cost of $95. Definitely beats buying the Sony E mount lenses, especially in image quality. Before you could tell that this was not a DSLR camera, but now my pictures look incredible, and have no loss of detail even while zooming in fully.However there are two things to note when you use this adapter. You have to use manual focus, and the weight of the lenses makes some shooting difficult without a tripod. The manual focus for these works great (even better than with the E mount lenses as they don't rotate forever), and the shoot tips button becomes a MF assist, allowing you to zoom in 7 or 14 times to check your focus. The infinity is slightly off on my canon lenses, and I have to twist it a little shy of infinity in order to focus correctly, but not a huge issue. Just learn how your lens works with the camera, it might be different but certainly didn't lose any of its quality or features. The second part is a much bigger problem with these, as you will be using much larger lenses on the camera, making the weight balance be entirely in the lens. With my prime lens it's not a problem, but with my telephoto I have to keep the shutter at least on 1/150 in order to not get blurry pictures. The E mount lenses have built in image stability, which is not present here. For photos this isn't particularly difficult to work around, but for videos they get extremely shaky. Definitely use a tripod to film video with this, but the video will look incredible if you do.The only other complaint is that the tripod mount is attached by TINY screws, I haven't found a screwdriver to take it off yet, but not a huge inconvenience.Simply put, if you have a couple FD lenses lying around, there's no reason you should not get this adapter. For a fairly cheap price, you'll turn have professional shooting capabilities, and this is definitely the cheapest way to get a diverse set of lenses under your belt.

I purchased 4 different version of this adapter for my Sony NEX-7. I have posted the same review for all 4 of them.1- Contax- G2, The fit is great on both camera and lense side and I did not notice any IQ degradation. The focus ring initially was a bit hard to work. Partly because the ring is close to the body and there is not much room. The lense also requires some torque to move the internal parts. But after I played with it attached to the lens but off the camera it losend up. Take your time attaching the lense to the adapter not to damage the focusing mechanism. Those of you who have this lense know why. I just wanted to remind you.2- Canon, The fit on the camera side has a bit of rotational play but dose not seems to effect the Proformance the lense side is perfect. I dont have recent canon lenses. My canon lens is very old, 70's 50 mm 1.4, no issue with the IQ. This was the first lense I ever bought. With a AT1 body.3- Leica M39, Both side fit is great but some some color aberrations on the edges. Not sure if I can fix it in LR.4- Nikon, The fit is great on both side. Great IQ no issues at all. I have an extensive collection of AFS and AF 2.8 and pro quality lenses as well as some kit lenses that I have collected as they came with backup cameras I purchased from time to time. So far any one that I have tried worked with out any issues.Over all the adapters are well made and great buy. Hope this help...

I bought 3 different adapters for canon FD-NEX. The ones I tested were the Fotodiox, the Neewer, and the Fogta. First, I shall reiterate what others have said, that these are manual focus and aperture adapters, and they do not use lens elements that reduce image quality. You set your NEX to allow lens release, and it has no communication with the lens. You do it all by hand, just like in the olden days, which is why I love using these so much!The Fotodiox was the most expensive, and, after some consideration, the best. At first, I did not like the fact that the Fotodiox is set a little past infinity. The fact is that I rarely focus straight to infinity on the lenses I am using--I am doing macro, portrait, and long telephoto lenses with these adapters, it's more likely to be a wide angle landscape lens that you send straight to infinity when you shoot, and I have that in my NEX kit lens (which strangely seems to lack a specific infinity point, but that's another story). I also now appreciate that this extra sliver of focus makes sure that you should be able to safely hit infinity on every lens, which was a concern with the other adapters. What I like most about the Fotodiox adapter is that it really fits the camera and lenses snugly with no play, unlike the cheaper adapters. So I tend to use this adapter on my long telephoto to make sure that it's extra secure. I'm buying one more adapter, and this will be the one, despite that it costs twice what the others cost.The cheaper Neewer and Fogta appear to be set at infinity, but each of them has a little bit of play in the mount--they're not completely snug. I later noticed that the Neewer sometimes seemed to hit infinity just right, and then sometimes, it couldn't reach infinity! Huh? It may have been temperature induced (had trouble hitting infinity in hotter weather), but I think it's more because of the play in the mount. Hitting infinity focus requires very tight tolerances. Since the adapter is a little loose, if it's not in complete contact with the camera, it will never reach infinity. I had to wiggle the lens and adapter while pulling it tight against my camera, and then it popped back to infinity. So it's a cheap mount, what do you expect? I'd rather have an adapter that's just a hair shorter, having that safety factor of going slightly beyond infinity. The apeture lock on the Neewer adapter is very smooth and buttery, so I appreciate that. I have not experienced the problem of not reaching infinity on the Fogta adapter; it does seem to be set on infinity, but knowing what a small tolerance that is, It wouldn't surprise me if there's a chance it might not always hit it on certain lenses since there's no room for error. My only complaint about the Fogta adapter is that the aperture lock ring is loose feeling. It's a little harder to snap into place, and then it kind of wiggles after you set it. I don't think that actually matters for its function, but it makes it feel cheaper. Also, the Fotodiox and Neewer shipped very quickly, and the Fogta took a few weeks to ship from China. I use the Fogta and Neewer adapters on my portrait and macro lenses, where I rarely need to think about infinity, and a little wiggle in the mount doesn't bother these smaller lenses.
