I got myself one a few weeks ago and couldn't be happier. I went from 5dmkiii to a7s and just really didnt get on with the colours the Sony put out. I tried every single in camera preset and so many luts but just couldn't get the colors i was wanting and found it took a very long time to grade the footage to match clips.
With the C100 mkii i find the colours extremely natural looking and also Clog seems a lot easier to work with then s-log2.
I got a package which came with the Atomos ninja star and i would highly recommend it. Some say its hard to notice a difference but i found with high detail and moving shots it makes a difference compared to the low internal compression.
If you want any sample clips just drop me a message and i can upload some raw clog for you to play with.
