If your lenses are motor drive, the LAEA-3 adapter is all you need, and cheaper than the LAEA-4. As has been said, you'll find E mount lenses more satisfactory.
The LAEA-3 is a little cheaper than the 4, but the 4 gives you compatibility with more lenses.
I had a 3, but replaced it with the 4. The 4 is really the more versatile and better adapter.
