I am the proud owner of a Panasonic GH1K, a couple of lenses, an adapter for my old Pentax SLR lenses, and a NIssin flash. I would classify myself as an enthusiastic amateur, with an emphasis on the amateur. Have been into photography on and off since 1970 (I am old). The GH1 is about 3 years old and I was thinking of upgrading to a new G6, or GH3, or ? Can I please ask for opinions from the experts on this forum, is it worthwhile to upgrade, what are the best options to give me better photos without sacrificing the compact size of MFT?
