I didn't shoot 1080p because the Komputerbay card can't write fast enough. I chose the maximum resolution, of course. And I wanted to shoot in 2.35:1. Gonna try a Transcend, Lexar or Komputerbay 64Gb card to see if the write speeds are better. By the way, 1080p isn't sharper than the resolution I shot, just bigger. Only if you blow the video up (for example on the max resolution of your retina display) it will look sharper yes, but that's an other thing..
