Francesco (06.13.14, 5:22 AM): Hi Michael good test! I was wondering about the effettive light entering the 2x crop sensor on the gh4. Does it lose an Fstop in comparison to full frame sensor? Do engineers compensate with some Iso trick? Thanks

Randy (06.12.14, 11:03 PM): The GH4 is pretty good. Thanks for the test.

jlawr (06.12.14, 9:56 PM): On a 2x crop sensor doesn't f/1.4 become f/2.8? And f/2.8 becomes f/ 5.6? So that kills shallow DOF.
