I guess that depends on what your needs are. If you want something that is quick and easy to use with no fuss then the 2.0 is probably more what you are looking for. But the 2.0 has a much smaller aperture range and there is no fine focus either. I think it is just the matter of what you prefer. I was going to get the 2.0 but while I was procrastinating the 3G came out and I will give that a go as it seems more suited to what I want.
