Richard Crook wrote on his blog a long post on the CPF-LOG Picture Profile for the Sony NEX-FS100. He has done a lot of work on what exactly each menu item in the picture profile settings do and what are the best settings to achieve the best desired looks after minimal and/or extensive color grading.

Richard reminds that the Sony NEX-FS100 uses a heavily compressed codec so that video clips are not meant to be pushed very far in the grade if you want to avoid aliasing, moiré and other unwanted effects.
 

"We found out early on that a dramatically flat picture profile is NOT the way to go. But there IS a safe medium, and we believe we found it."

According to Richard, the CPF-LOG profile was created especially to maintain highlight and shadow detail and a color gamut that grades very well whether you do alot of grading or a quick fast-color correction.

"This profile is created as a part of a workflow that is setup for color grading in post. IF YOU DO NOT INTEND ON COLOR GRADING IN POST, THIS PROFILE IS NOT FOR YOU. In the very least, it is recommended that you correct the black and white levels, pull the middle grey down to around 35-40%, and adjust saturation to taste."

A cool thing about the profile is that it includes a Look-Up-Table:

"A LUT is designed to give the camera operator or any other viewer on set the ability to see a preview image of the video with a filmlike gamma curve and color setting applied. A LUT is NOT intended for actual grading. Even if you wanted to, applying a LUT to footage as a final grade defeats the whole purpose of shooting a LOG image and color grading in the first place."

If you want to use the profile make sure you don't adjust any of the profile settings.

"It’s also a good idea to switch back and forth to the LOG profile because it will show any possible details you may have missed…but you DO NOT want to use the log profile to adjust exposures/lighting, etc. It is also recommended you set your ZEBRAS to 100% and if you see them show up on highlights, stop down/adjust ISO or shutter until they are almost about to disappear."
