I've compared the new Technicolor Profile for the 5D with the standard Canon profile for the exact same settings. It's great to work with such an "untouched" picture! As you can see the compression of the Canon profile is much heavier than the Technicolor profile. Next week I'll try some grading with the footage.
In addition, I've also compared my two 50mm lenses:
Canon 50mm 1.2 (adjusted to 1.4 for the exact same setup) vs. Olympus 1.4
