Excellent.

Lovely item - would buy again from this seller.

This is a review of the adapter that attaches a Canon-FD mount lens to Sony NEX (E-mount) body.A Canon 50mm F1.8 lens attaches cleanly and firmly to the adapter, and the adapter attaches cleanly and firmly to the camera. When the release button is pressed on the lens, the lens and adapter separate easily, as expected.If the adapter has a drawback it is that it is easy to rotate the "lock-open" ring by accident. This doesn't release the lens but in the "open" position the aperture doesn't close down when the aperture dial is rotated. The worst case situation is that the "lock-open" ring is partially rotated and then the aperture will close partially but not fully. On the other hand this same "lock-open" ring is useful because when used properly it provides, in essence, a binary control for the aperture: In the open position the aperture is wide open giving minimum depth of field and the image is bright and this is ideal for using the Sony NEX focus highlight feature. Then, once the focus position is set, and the aperture will close to whatever position has been set on the lens's aperture ring.I have two adapters to attach Canon FD lenses to Sony NEX bodies. One adapter is branded "K&F" and the other is branded "Beschoi". Apart from the brand texts, the adapters appear to be identical and perform equally.A 35-105mm Vivitar lens does not mount properly onto the adapter, or at least not in a way that gives me confidence it will stay attached. However after much faffing and investigation I found that I had exactly the same struggles attaching the lens to a Canon body, and therefore the adapter cannot be blamed. It is possible that the Vivitar lens is defective in some way but I do not have the experience that would let me be sure. The Vivitar lens has its own mounting lock ring and therefore the mounting operation is a little different to the Canon lens. I mention this only in case somebody else is struggling similarly and wondering which bit, if any, is at fault.

Excellent for mating my grand-dad's Canon 50mm fixed focus to my Sony NEX.

Works fine for meDoes what it has to do

Very good adapter, I shoot with multiple FD lenses on my Sony and it works perfectly.

I now own four of these adapters; Leica M and M42, Canon FD and Olympus OM, all to the Sony NEX mount. The build quality of all four is superb and much better that you would expect for the price. The Canon FD version in particular has a ring to lock and unlock the aperture - this is butter smooth and really well damped. Make sure it is set to LOCK when mounting so that the aperture ring works.Mounting surfaces are nice smooth chromed brass or aluminium. We'll see about long-term durability but I expect these to last the distance - top quality.Lastly, though one reviewer appears to have had problems, I can say that contrary to the manufacturer's details all four of these adapters work perfectly on my Sony A7R mk2 - locking securely and with no play.

Works as expected.

It mentions that is't not compatible with the Sony A7R II, however it works perfectly on mine! Well worth the money, to open up the possibilities of using so many other lenses.
