High quality, works well
This adapter works perfectly for old Canon FD lenses. The aperture ring has worked on all the lenses I’ve tried (extension tubes also worked). Some lenses don’t require the adapter’s “lock” ring to be turned, like the 50mm f/1.4 SSC with the breech lock, but the ones that do need to be locked work as expected. Of course, make sure to turn the lock ring to “open” before changing lenses. This adapter does NOT come with any front or rear caps. (If you plan on leaving this adapter attached to one lens, you’ll want that rear lens cap to keep it sealed, and clearly you can’t use your FD rear cap unless you detach the adapter between uses.) It’s made of what seems to be good quality metal, not very heavy. It attaches to my A7 IV solidly without any slack. Lenses also do not have any slack. And for extra clarity, this adapter has no need for glass because the flange distance on the E mount is shorter than the FD mount. Also, there are no electronics here so don’t expect that “A” mode on your FD aperture ring to work. Usually when you use stuff like this or switch to manual focus, Sony bodies will automatically turn on focus peaking. You’ll definitely want that feature enabled so you can focus accurately. So far I’ve had no problems with focus at all. I was originally looking at a more expensive FD to E adapter, but honestly this one has worked perfectly and intuitively so far.

The Perfect Product for the price - Fair quality and it does the job for a fair price
I used this adapter on my Sony A7ii purchasing 2 of them. The build quality is amazing, there is no gap and the adapter fits perfectly to the A7 E-mount. One of the 2 items came perfect, while the second has is very tight for an adapter built to have a button release and change the lens on the go. The other adapter was simply perfect and I can't complain at all. Since I purchase an adapter for every lens I use: much more comfortable with the idea of having lenses ready to go, the fast release button is not a big deal and so the "tight" item which came is not a problem at all to me. I tried many items on the Market for Nikon Manual Lenses Pre AI (I have a bunch of Nikon-Q Lenses) and this adapter is the only one with no issues at all. In long exposures no light filters through the plastic mount and the camera and the same is for the metal Nikon female Mount. It was not available in Amazon Italy and I ordered it in U.S, why? - Overall the price is fair, not really cheap but it's the best value for the money: cheaper adapters have issues. This one is perfect and will do the job with manual Nikon Lenses - The built quality is not outstanding: the male E-Mount is made out of plastic, if on one hand this sounds bad, it's good because it's not going to make damages to your camera as other cheaper adapters which are made out of cheap metals and will scratch the native Female E-Mount, even if it's out of plastic light does not filters in and this is another good reason to buy it. Long exposures are guaranteed. The Nikon Mount is perfect and made out of good quality metal, even if there was that annoying difference which make one adapter perfect and the other very tight (but still usable), so it would be a painful process using the release metal button to change the lens. I decided to take it. - Cheaper adapters have sometimes major issues, while this model is simple but works well, it costs for not having any electrical parts but it's a fair price to pay if you use old manual lenses. - I use the strategy One adapter - One Lens: if you are like me, this is the product made for you. In case it has the release button which comes handy if you want to switch lens. - No loss of light: I tried my Nikon Lenses in my lab with a Nikon D750 and the Adapter paired with a Sony A7ii: I had equivalent result in terms of lighting while shooting both with the Nikon and the Sony. Same aperture/iso/shutter speed: same histogram on Lightroom. - The same brand and model has almost every kind of Mount (Canon/Minolta....). I'm enjoining this product very much.

Fotasy vs. Gobe Nikon to Sony Adapter: Which is best?
I’m a well-known pro and specialize in tech and imaging reviews. If you are reading this review you already know older Nikon lenses are great. Are these adapters viable? Is Gobe worth paying 80% more compared to the near identical Fotasy? Have a look at my photo and read on: First, let me tell you you’ll lose no optical quality with either. If you are willing to go with manual focus only, these are great. I bought the converter for Nikon’s great macros and it’s best to focus this type of lens manually anyway. For exposure, the Sony AV Aperture Mode does work! Or just use manual exposure, too. With these, it’s strictly manual focus. Now, let’s look at each converter in more detail: COMPARING GOBE VS. FOTASY ADAPTERS: Of the two adapters, the nod goes to Gobe. It’s $13 more so not a big deal in the long run. Build quality is equal . . . except for the silver tab you press down to release the lens from adapter. The Fotasy does work but you have to muscle it. The Gobe is smooth and easy. With either, simply press down to release the lens. Both the Fotasy and Gobe and nice and tight when attached to the Sony camera body. Neither wiggles or wobbles like some adapters do. Of the two, I’m keeping the Gobe but am perturbed by some issues with their packaging and “too clever” marketing. We truly care about the environment, too, but this is an adapter connecting to lenses worth hundreds to thousands of dollars. No instructions, whatsoever, Gobe?!! The only paperwork included is an offer to save five trees. Really! Gobe’s website is no better. Getting the adapter on the lens is intuitive. Without instructions, getting it off may confuse some otherwise quite smart people. Once you find the silver latch at the left, just depress it and carefully slide the adapter off your lenses. Simple, once you know how. Next, it comes with a hip canvas bag to store the adapter in. But so unwise!!! This adapter goes right up against your exposed camera sensor. This type of bag can shed particles into your expensive Sony! So, please never store it in the bag without additional protection! I got around this by placing the Gobe in a small plastic bag inside the canvas bag. Then, the now protected adapter can store in the pull string bag, if you desire. I STRONGLY suggest Gobe rethink this poor decision. RECOMMENDATION: Bite the bullet and spend the extra $13 on the Gobe. Either of these adapters are 100% pass-through devices with zero effect on lens quality. If your budget is tight, you’ll find the Fotasy just fine, too.

Excelente adaptador, se conecta firmemente tanto a la cámara como al lente, cuenta con un swich que al ser girado habilita la posibilidad de cambiar la apertura del diafragma de manera manual, el adaptador no tinen ningun elemento dentro por lo que la imagen pasa con claridad directo del lente a sensor. PRO: - Usal lentes viejos en camaras nuevas sin espejo. - Permite el control completo del lente conectado a la camara. - Hace justo lo que se anuncia. CON - No tiene soporte para tripie

The screw that holds in the locking clip and spring in place broke off 4 days after the return window closed. I appreciate the refund when I contacted support as I didn't have faith that a replacement would do the job. A disappointing purchase but well handled by Amazon.

Great little adapter that seems to fit perfectly on my e-mount camera. I am not sure if there is light-leak, but the images look great so far! Recommended over some of the others that say they do not fit the A7II. I thought all e-mount cameras fit the same? This one definitely works well on the A7II, so it should work well with the A7III series as well.

I'm 💯 Satisfied

Though this is just an adaptor without any electronics, it does fit well between my Sony cameras (A7iii and A7C) and canon L lenses that i own. You have to adjust focus manually, ideal for either fixed object video, or simple photo shoot where you have to achieve focus manually.
