Does Exactly What I Expected It To Do.
In short, This did exactly what I wanted it to. it allows me the use of my old FD mount lenses on a EOS/EFS body, and does an extremely good job at it. construction of it is solid no looseness at all. have had no problem mounting any lens to it. I would buy again and have already recommended it to my friends with the same interest. In more detail, This adaptor does exactly what it said it would. the instructions were very clear. and packed very nicely. it's compact enough to take next to no room in any camera bag. and the thing I was most concerned about, I've read advisories about these adapters (Not this brand but as a whole) blocking the mirror from flipping properly from being too close into the body. This one did not have that problem at all. Another concern was it's ability to support weight. the old FD lenses were not lite being made of glass and metal, but this has been no problem at all I've had a telephoto hooked up to it without any concern of it falling off or worse yet damaging the mount's on the camera body. as I said at the start the adapter is made very well. of nice metal and glass there is nothing on it at all that would make me feel like it was cheap. If I could change one thing it would be the color. the bright blue ring stands out like a sore thumb. but hey you're taking pictures of other things so in the long run it does not matter how it looks doing it. As you could imagine using a FD lens you'll lose all your snazzy features that the lenses of today offer you. there is no image stabilizer so for someone like me that's a little of a set back I can tend to bump the camera at times so a tripod is almost a must, there is no autofocus it's all done by manual (I mainly shoot with MF at any rate though) aperture is semi manual. you do have the ability to set the light sensitivity of your camera and than adjust the lens aperture but that leads into a trick I'll detail in a second, as a whole this is a amazing adapter that I wont be without from now on. it allows me to use all the lenses my grandfather's and uncle gave me rather letting them just become forgotten about. Depending on how your lenses were taken care of they might need to be taken in for cleaning. the ones I have gotten were always kept in a thermal camera bag and never bothered so they're great. but a lot of them have dust even meldo in them. don't let this put you off. they can be cleaned and brought back to their youth by a professional and still more cost effective than buying that lens new. different lenses are different quality. I've had amazing luck with my 70-200, 35-105, and 100 macro, but had a little bit of a love loss with a 50MM prime. it just was not as clear as I wanted it, this is in no way due to the adaptor however it's a factor of the lens itself. but the reason I brought it up is to say one lens may look bad but don't knock this adapter for that, try again and see if you can get better results. That pretty much wraps up my review of this adapter I'll now go over the trick, I found that adjusting the "Install" ring can allow you to manually over ride the aperture of the lens. I found often times when the picture was just too dark and turning your shutter time to 30 seconds didn't do much either. that turning the ring back towards the install mark would allow the image to brighten up substantially, being that the ring is free turning there are no clicks it's a great way to get that perfect brightness just like using a dimmer knob. when I get the chance I'll be uploading pictures I've taken with this and the lens used. hope I was able to answer some questions and should you have any further questions or just want to discuss it over all before buying feel free to let me know I'll be more than happy to go over it with you.

Works quite well
This product is well made, sturdy, and functions perfectly, with minimal loss of focal range on crop-frame bodies, and I have discovered no loss of focal range on full-frame sensors yet. First off, I am a professional photographer and photojournalist who uses my camera's everyday. I came across a box of lenses fro the mid 1970s and wanted to see how they behave with my modern Canon digital bodies. The end result is that I am now using these old lenses, many of which sell for under $50 on auction sites, more than my Canon L-series lenses. And this little chunk of machined metal is what lets me do it. There are not many things that can go wrong here, as the adapter is simply a chunk of machined metal. The one I received is, in fact a very well machined chunk of metal that fit's perfectly into the EOS mount of all of my Canon bodies, even an old A2, with no wiggle or slop. The M42 threads are also equally machined, and lenses thread in smooth. Of course you do loose all automated functions when you use it, but most of the lenses you would use it for are fully manual anyway, so nothing lost there. You do also loose the little red square confirming your focus but once again, you are just loosing a modern enhancement, Photographers have been using their eyeballs to focus in much smaller viewfinders than my 7D for many years. On my crop-frame bodies, I do lose the ability to focus out to infinity, but only at around 400 mm. Any lens under that functions normally from its closest focal point on out to infinity. I have shot out to 600 mm on full-frame and film, and seen no loss of infinity focus.

Solid construction
This is very well made, and has a solid feel. I never got the impression that it was a cheap, plastic toy. As others have mentioned, it's very fuzzy at the first aperture position, so be sure to start at your second most open aperture setting to get decent results. As you get farther into the middle (f/5.6, f/8, or f/11), you'll see a marked improvement in the image quality. I had a bit of trouble getting it on my lenses the first few times. It's very precision made, so there's not much play to work with. Some lenses make it easier to install than on other lenses, but once on, it's a solid fit and works well. With practice, putting it on and taking it off takes mere seconds once you get the hang of it. Once it's on the lens, installing it to the camera is as easy as installing an EOS lens. I finally tried removing the lens on the adapter to use it as a macro extension tube. It was a bit of a trick as the lens was rather securely screwed into place, but once I got it off, my lens was transformed into a macro lens with good results. If you slide the blue ring to the appropriate position (see your instructions), you can use the aperture ring on your lens and it will definitely allow you to adjust the aperture. You will also have focus available as these old lenses are manually focused, and it's much easier to focus these old lenses than the newer, autofocus lenses because of the difference in the gear ratios. Best of both worlds, and a good compliment to my backpack of other accessories. For the price, I'd recommend getting this just to have some fun with your old lenses. Mine aren't as sharp as my kit lenses that came with my T3, but they're still pretty good, and there are lots of better FD lenses available for much less than we would've paid years ago. For the price, you can buy more lenses and have even more fun without having to go bankrupt buying newer lenses that cost way more.

Allora, prezzo alto, ma vale la spesa, ho 2 lumix (una M4/3 e un full frame) ed una Canon EOS, ho comprato un unico adattatore perché fondamentalmente se unito con altri adattatori per le rispettive lumix posso collegare l'obbiettivo della mia fujica su tutte le mie camere, l'adattatore è di ottima fattura e presenta una linguetta di ferro che va a tenere in maniera perenne la visualizzazione del diaframma (sulla mia fujica stx-1 c'era un bottone, ma una volta tolto il dito tornava in posizione) in questo modo si può regolare comodamente il diaframma, cosa non da poco, gli altri adattatori che ho provato nessuno mi dava la possibilità di usare i vari diaframmi degli obbiettivi, solo quello vale il prezzo, se unito ad adattatore EOS-L mount ho potuto rendere utilizzabile l'obbiettivo sulla s5iix, senza questa soluzione avevo il problema del tiraggio che non mi permetteva di usare gli obbiettivi, non fa strani giochi, insomma, super consigliato per avere scatti unici alle nostre foto, di seguito metto una foto scattata con questa soluzione sulla mia full frame, senza la minima post produzione

Construction solide, il faut juste appuyer sur le plot de fermeture de diaphragme de l'objectif pour qu'il passe sous la pièce qui le maintient sur la bague. Monter la bague sur l'objectif avant de monter le tout sur le boîtier, ensuite il s'adapte comme tout objectif canon EF/EFS. Parfait, sans jeu et très pratique pour utiliser d'anciennes optiques de qualité (dans mon cas ZEISS T*) sur son Reflex numérique. Très bon produit avec un prix un peu élevé mais sur la durée, rapidement amorti.

Al fin he podido dar uso a los viejos objetivos de mi padre de Yashica. Funciona correctamente y así me ahorro dinero en objetivos nuevos. Por el precio que tiene merece la pena recuperar antiguas lentes.

canon eos5dmark2で使用してみました。 作りはしっかりしています。メタリックブルーの色合いも落ち着いた感じでいいワンポイントになります。簡単な説明書もはいってますが日本語説明はありません。 アダプターを使っている人なら分からないことはないと思います。 フルサイズ機なので望遠ズームでは周辺減光がハッキリ出ています。 APS-CやM4/3では減光なく綺麗に撮影できそうです。 広角レンズでは周辺減光なく撮影されてます。 補正レンズが入っているので絞りは1段分ほど暗くなってしまうようですが それを加味しても充分使えるアダプターだと思います。
