Notices before purchasing:
- Canon STM series lenses don't work with our EOS adapters.
- STM lens (such as EF 50mm f/1.8 STM, EF 18-135 IS STM) requires to be powered to drive the motor to focus, so cannot achieve focus with manual adapters.
- Manual adapters have no electronic contacts, which therefore don't support auto-focus or aperture control. K&F Concept lens mount adapters are all manual ones.
- Please figure out the mount of your camera and lens in case of buying the wrong adapter.

Specifically refer to the camera manual，Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate while using this adapter.There is no electrical contacts in the adapter ring. Full manual operation,manual focus, manual iris adjustment can be achieved with body manual exposure,aperture priority exposure.In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body.You can shoot in Manual or Aperture Priority Mode. Before use, set your camera Menu: "Shoot without lens".

There is confusion on what these mechanical adapters do. I use the Canon eos to Nex (sony e) on on A7RII A7RIII and A9. You must set in the camera menu to"shoot with no lens attached" ! If a traditional electronic lens like the Canon EOS lens is attached, no electrical communication will happen between the camera and lens. (camera will think "no lens attached"). You will have no f stop, auto-focus, vibration reduction.If you use some of the excellent "all mechanical" Chinese or vintage lens with mechanical f-stop and focus rings, you use the rings on the lens to set f-stop and focus. This is an all mechanical solution that works great on so many of the excellent mechanical macro and wide angle lens. I use with Venus 12mm lens EOS mount and various vintage Leica R lens that have been converted to EOS mounts. All these EOS mount mechanical lens work great on the Sony E mount!!

Received this today fits nice like factory. Tightens and loosens like it's suppose no issues. One thing for a heads up there is no changing the f-stop it's lock wide open but for me that's what I shoot. Twenty bucks well spent for me until I get some Sony lenses this will do. You won't be disappointed.

Works, but fairly expensive compared to other brands (Beschoi). I also had to return mine because the threads were way too tight to fit on an a6300.

Works as advertised on my Sony A6000 with a Sigma lens meant for a Canon EOS body. Remember there are no electrical connections with the camera body. You have to manual focus and zoom the lens. I have no problem by leaving the camera on P mode (auto program). The exposure was fine and the speed seemed to have set itself automatically....no blur. For the money, it works as advertised and is nicely manufactured....seems to be all metal. I'm very happy with it.

This adapter fits snuggly allowing me to use my Canon EOS lenses on my Sony a6000.I do have to focus manually, but no problem unless I forget. Very happy with this purchase.It arrived promptly and well packaged. I would recommend this adapter.

This is not for professional use whatsoever. You cannot control the f-stop of your lens. That should be said plainly in the description. What's the point of being able to connect the lens if you can't control the aperture or depth of field? Only get this if you have an older manual lens or a rokinon where you can manually adjust the f-stop from the lens itself.

I ordered two, one for a Sony FS7 and one for a Sony A7s. One of the adapters was tight, but firm and solid. The other was WAY to tight. I had to sand and file down the flanges to even get it on, and I had to sand and file the EF mount side as well (I unscrewed the mount and filed the back-side where the springs are) to get it to fit. Still a little tight, but I imagine with time it will be better.

Not sure why the product info states it doesn't work with the A7 II, got mine and it fits snug and confidently holds my MF lens. Fantastic metal body feels like it can hold anything.

Fa perfettamente quel che deve fare. Ho diverse ottiche vecchie con attacco avite 42x1, Nikon AI, Olympus, Contax/Yashica, e così via, tutte con anello adattatore per Canon EOS (il sitema che usavo prima di Sony). Quindi, quando le attacco alla Sony A6000 con l'anello K&F, hanno due adattatori in serie: la cosa non crea problemi, l'assemblaggio è solido e senza giochi.Naturalmente, usando le ottiche EOS originali che mancano di comando manuale del diaframma, non c'è modo di impostare l'apertura, perché non c'è trasmissione di comandi da macchina ad obiettivo. Questo è indicato comunque nella descrizione del prodotto: se l'esigneza è quella di usare in pieno le ottiche EOS, occorre prendere un anello con trasmissione dei contatti, molto più costoso.L'anello è forse un po' corto, e le ottiche mettono a fuoco "oltre l'infinito". Alcuni ritengono che questo sia un grosso difetto: io credo invece che sia una cosa positiva e probabilmente l'anello è fatto così volutamente. In questo modo si ha la garanzia di mettere sempre a fuoco all'infinito, anche con ottiche, ce ne sono tante, con attacchi trasformati artigianalmente e talvolta in modo grossolano.

Cumple perfectamente con sus funciones, gracias al daptador puedo combinar objetivos antiguos con mi cámara Sony Alpha 5000. Estoy contento con el resultado. Lo único que no me deja variar la la F, no me muestra valor y parpadea, si alguien me pudiera ayudar...

Très bonne finition et prix contenu, cette bague d'adaptation me permet d'utiliser les objectif canon EF sur mon alpha 7. Evidemment à ce niveau de prix on perd l'autofocus et le réglage de l'ouverture mais pour mon usage pas de souci.Bref parfait et livré très rapidement en Amazon Prime
