I'm looking to upgrade from the Lumix GF2 but confused by the range of CSC cameras on offer. I want to stick with M43 Lumix CSC as I already have a number to lenses however looking for something more towards the DLSR side of the scope but not as bulky. I am by no means a professional but would like a camera I can develop with. Video not necessary/priority So which one would you recommend? GF5 GX7 G1 GH4 G6 GM1 Although I have listed the newest model above I am happy to go for an older version... Thanks in advance!
