I thin most mu43 members would choose the E-M1 if they were getting a free camera without the ability to sell it. It seems that most people think the E-M1 is the most significant m4/3 camera release of the past year. I disagree. Even if I prefer my E-M1 over the GH4 I cannot understate it's significance. 4k is no joke and the GH4 is amazing. it is far from perfect. The EVF really should have been on par with E-M1 but while the E-m1 is an iterative improvement over the E-M5 the same cannot be said of the Gh4 over the GH3. The GH4 is revolutionary much like the GH2 but more so. The GH2 Hacked was amazing but the stock GH4 is revolutionary. DFD is an incredible improvement in mirrorless tech. Panny has undersold it significantly. I truly believe it is better then the pdaf of the E-M1 and will be able to confirm in a week or so hopefully. The 1.4 firmware update was the best so far so I am not sure atm but I'll try to update soon. I am too tired to continue atm. I'll write more in the next few days ins.
