Hi I'm new here. I have a GF2 currently with 20mm and 14-140mm. I am thinking of getting a G3 to mount the 14-140mm since I was thinking about getting the external VF for my GF2. So instead of spending $ on the VF, I'd thought why not get the G3.. Is this a waste of money? Are GF2 and G3 essentially the same camera? I may in future decide to sell the GF2 and get a GF3 for even more lightweight occasions. I guess I am wondering, did I buy a camera (GF2) that is in between GF3 and G3... ?
