I just got my hands on it and it feels perfect. I liked my G-2 but this has all the things I was missing... I was wondering anyone could advise me about the following: 1) Are there any great tutorials or sources of how-to regarding this camera? 2) I have an olympus 40-15o 4/3 and can't seem to get rid of it. What kind of converter might work for this lens on my G-3? Would I lose auto focus? 3) I have an extra battery for the G-2. Realize now the G-3 uses an extra battery. You can have it for the cost of shipping or $10 or whatever seems fair.
