The adapter is exactly what I was looking for - inexpensive and good! I have a Nex 3N as a backup for my A77 and was / am not willing to spend 300.- for the Sony LA-EA2. Therefore this purchase. Granted I was only very skeptical at this price ... - but was disabused :-) The only restriction is the build quality is to say, which is not particularly good - so does the tailor-made operation, however no harm. I'm using a Sigma 18-250 and a Sigma 50 - 500. Of course, the aperture and focus must be adjusted manually.
