I was getting between 4 - 8 seconds of real time recording at 1080p with a 2.35:1 crop.
Lens's were all L series glass. 50 f1.2, 24-105 f4, 35 f1.4, 100 f2.8 macro, 16-35 II f2.8
I don't have the HQ version online sorry. I might upload it. Its basically sharper and you can see the grain much finer.
Thanks
