I was wondering: can I just use the picture profile from a C100 on a C100 MkII, or are there any differences?
I'm considering hiring a C100 MkII and it would be nice if the C100 color profiles can be used.

As far as I'm aware, there was no change between the C100 and C100 Mk. II with regard to Picture Profiles. You should be able to freely swap them between the two cameras. Anybody know for sure if I'm right or wrong about this?

I use the same profiles on both cameras. They're pretty close. The MkII is a warmer camera in my opinion, and a tad more sensitive, but expose similarly and you should be good to go. A little color correction to compensate for different lenses, angles. Nothing too difficult.

However, I wasn't able to simply copy the settings over via SD card, I had to enter the settings manually.

Thanks!
That is good to know :-)
I'll make sure to have the settings on paper then.

Yeah. Unfortunately you can't import the c100 profiles directly into the camera. You have to build from scratch.
