1. AF/AE lock button works perfectly 2. Standard profile have good colors, -5 contrast looks good, but combined with -5 saturation the skin tones goes to orange. I use Supertone if i want to go filmic ( http://www.supertone.dk/#!GH4-Optimal-Film-Setting-works-in-stills-too/c24o4/8E18836A-F271-4A14-AF0D-C575B9D5F4B6 ), and Standard 0,-1,-4,0 if i want massive colors. It's hard to get nice flat from LX100 (Maybe Standard -5,-5,-5,-3 without curves is the best choice) 3. iDynamic is lifting the shadows heavily, With iDynamic High you can underexpose the image more than -1,33 EV, and it will still looks good. But it comes with lot of noise, even at ISO 200. But the image is contrasty and colorfull, and the dynamic range is expanded, so i think iDynamic: Low, -0,66 EV exp correction give you nice results. iRes is useless i think. 4. The Luma range is 16-255 on the LX100, Earlier version of FCPX had some trouble with it, but in 10.2 it's fine.
