I've had the GH1, 2 & 3 and was considering upgrading to the GH4. I've got a decent range of Micro 4/3rd lenses which was part of the reason I stuck with the Lumix line. The specs on the Sony A7rII look miles ahead of any camera at the minute. Am I right in thinking that the Micro Four Third lenses are only suited for the smaller sensors? There's no chance the Lumix sensors can get any bigger? If I were to sell my GH3 and lenses (14-140mm, 20mm, Nokton 25mm 0.95, among others) what lenses should I get with the A7rII?
