if you get the c200A you can literally film with the body and an xlr mic - thats pretty stunning being the smallest professional package that is relible and controlable and robust.
I like the B model and say you were a gimbal op then it is the thing.. but for walkabout the A is pretty spacial.

I bought the r6 so I could 'pop' to an event in the city centre on the bus and do a few shots.. but in reality id take the c200 with a proper mic, proper ND and semi sensible battery life.
(i own c200, r6, and my colleague has 2 r5s)
an event.. filmed on the z6.. https://vimeo.com/527072583 this made some money.

Thanks for the videos, I do not have a problem with image quality with neither for the type of work I do. I am even okay with the 8bit on the C200 since it has a raw option. The R5c is a toy but it's one that can do 8k/60p in raw, the biggest problem with those toys is that they lack in I/O yet they are hybrid if you do some photography. The new Tascam xlr hot shoe audio adapter solves part of the problem but the mini HDMI is a problem.
My biggest gripe with the C200 is it's EF mount and that I can not use RF lenses on it. At the same time for interviews I would probably be using a 50mm most of the time and for multi-cam conference shoots I will have the proper I/O's. The C200 is going to excel in form factor and i/o yet the R5c will beat it in every other category. It might be best to be patient and wait till next month to see what Canon and others will release for the NAB.
