Not a bad alternative to the original adapter

Adapter is made entirely of metal and fits comfortably in your hand. It must be remembered that this is to be a complete analog part and therefore there is no communication to the body. It does, however, with a really good lens to photograph fun. In short, it does what it is!

Unfortunately, I have a little play between the adapter and Boby found, but I have also in my kit lens ;-).

When I am asked, I would say "I would recommend it completely, without having a bad conscience."

Oh, the delivery was quite fast, as usual.
