Does what I expected it to do. I have just bought my first full frame Sony A7. My last camera being a now very old canon 350d. At the moment I can not afford to buy a lease that covers that 200mm range so need to use my old Tamron lense. Manual focus and no control of aperture but does seem to work with the peaking function. But for the price does what I needed it to do.

Bought to use vintage manual M42 lenses adapted to EF on my Sony A7iii. The K&F Concept EF to Nex adapter works perfectly. It has a nice firm connection to the camera body and all of my EF adapted lenses fit very well. Lenses focus as they should.Worth £25 to be able to use vintage lenses on a digital body.

I recently purchased this to use my canon lenses on my Sony a6300. I primarily bought it to use my 50mm on it but it doesn't work. This is due to the 50mm having an electronic motor focusing system that means it can't be found through the adapter. However, I tried my 14mm Samyang and that works perfectly. The manual focus works as it should, as with my 75-300mm zoom lens that works perfectly too. I guess it's just something to do with the electronics on some lenses, so be careful before you buy, just a heads up!Otherwise, very happy with the product, sturdy, metal and no play within lens contact.

Quality is fantastic, mounts feel very secure.I use this to attach my Canon 50mm 1.8 onto my Sony A7S II. Obviously focus is all manual, but with the A7S II's focus peaking system I actually like nailing in my focus manually for a change.Something to note is that if you do have a lens like the 50mm 1.8 which does not have an aperture ring, like some vintage lenses you see may have, you will have to set your aperture on a canon DSLR first and then attach it to your other camera system. This means if you plan on changing aperture on a shoot you'll have to bring along your canon camera. Personally, I just leave mine wide open at 1.8 because if I'm using that lens it's because I'm looking for that depth of field.
