Yes but then why is any c-series camera OK? Shouldn't it be a RED or ARRI if you have to play that game?
This question assumes that most clients are versed in camera models/specs and manufacturers which is not the case. Maybe some producers/agencies but in my case most of my bookings come directly from corporate clients (some agencies and most of them do not ask or care what cameras I use). Your C200 is a professional full size camera that would do the job in both capture quality and client impression. The C70 would be a good addition if you need something more portable for b-roll and as a second camera for interviews, if not, run your business wisely and keep that money instead of giving it away.
