The camera format wars are generally a thing of the past. Things could get very heated on the DPR forums. I see in one of the picture threads, that the old debate has resurfaced. I do not want to join in thre and pollute that thread. So perhaps a separate thread is worth making, to discover if M43 is a "serious" format.
I thought it was pretty balanced, back in the day, but it earnt me a ban thanks to the shit show, it generated.
