K&F Concept C/Y (Contax/Yashica) SLR Lens Mount to Sony E Camera Body Adapter Ring, matte lacquer, C/Y-E IV PRO
SKU: KF06.514
Ring Used to adapt a Tamron 70-200 F/2.8 in A-mount to my A7s in E-mount Quite hard enough to connect on the lens side and soft on the A7s side (it's better than the other way around.. .) the membrane ring is easy to handle. The infinity is preserved. The price remains fairly steep, but the build quality is visible and the results are there: no play on either side of the ring.

recently bought this to use my Canon lenses on my Sony a6300. I bought it mainly to use my 50mm on it but it doesn't work. This is because the 50mm lens has an electronic motorized focusing system, which means it cannot be found through the adapter. However, I tried my 14mm Samyang and it works perfectly. Manual focus works as it should, as does my 75-300mm zoom lens, which also works perfectly. I think it just has something to do with the electronics of some lenses so be careful before you buy, just a warning! Otherwise very happy with the product, sturdy, metal and no play in the lens contact.

Does what I expected. I just bought my first full frame Sony A7. My last camera was a now very old Canon 350d. At the moment I can't afford to buy a lease that covers that 200mm range so I have to use my old Tamron lens. Manual focus and no aperture control, but seems to work with the peaking feature. But for the price it does what I need.

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

Read the reviews for the previous iteration and they were mixed. I went for it because I knew I could return it, but I won't. Haven't used it with the sun near the field of view yet so can't say if the matte interior reduces flare. Feels good and at this price I can buy one for every lens I need.

These things are a real steal considering the world they open up to you if you love frugal lens photography!

Thought the shape would be okay, but lenses with old dots can be used without problems. Good

The quality feels very good, had much worse. Nothing wobbles and sits very firmly on the lens and the camera.
