Nope. I'm just copy pasting a FB post of Filippo Chiesa (https://www.youtube.com/channel/UCeDcSWVeLZnSj6N9JjNexyw)
He meant "TV Network," and in the comments he specifies that they have made up 90 percent of his customers for many, many years. He rarely gets asked for a Canon camera, but he specifies that everyone's experience may be different. He has a pragmatic approach: if you film on your own, use the camera you like best. If you work on commission, use the camera the client asks for.
