A nice camera gadget to have for your Sony e-mount camera
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.

Sony a6000 to EF mount
Great adapter. Using my Canon 70-200mm to my Sony a6000.. FYI this is for manual focus only, set focus peaking on the camera. Also set the aperture of the canon lens to your desired f-stop with a careful trick. Overall it works great! Recommended.

Received this today fits nice like factory
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.

Great adapter, solid build and great look
I own a number of legacy lenses that I use on my a6000. I also have a number of no-frills adapters from different brands. While all of them get the job done, K&F is one of my favorite. K&F seems to be a bit pricier than other brands but I like the look and feel of their adapters. Quality metal finish, sturdy feel and easy to use and remove. I used this adapter to connect the Canon 100mm Macro (non-L) to my a6000 before I ultimately sold both the lens and the adapter. The reason I sold both was because I ended up buying vintage macro lenses which had aperture rings. Using EOS lenses that don't have an aperture ring makes it difficult to change the aperture. You have to set the aperture while the lens is mounted on an EOS camera and then mount it onto the adapter. It was a bit cumbersome for my needs. It something to be aware of if you're serious in using EOS lenses on your alpha gear.

This adapter does not support aperture...
This adapter does not support aperture... I was trying to use it with my Sony A7s and it doesn't see the aperture. Don't but this adapter!

Great for mechanical (non-electrical) 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!!

Not for professional use. Period.
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.
