I'm getting conflicting information here. On DPR, someone said the GH4's crop factor in 4K UHD (3840x2160p) is 2.6x relative to full frame. Andrew is saying that the GH4's crop factor is 2.3x relative to full frame. What's with the discrepancy here? Btw, I'm referring to the GH4 using native micro 4/3 lenses.
