I have just received my new Nex-3 body this last Saturday. Played with it all weekend, and I'm really, really pleased with it. Wonderful with my Minolta MC Rokkors, the 16, 21, 35/1.8, 58/1.2, 85/1.7, 100/2.8, 135/2.8 and 200/3.5.
I have several sets of Minolta MC Extension tubes that will work just great with the Nex-3. Tubes work best with normal to longer focal length lenses.
