Canon has been cashing in on the success generated from 5D MKII, and truly they have not cared to be on the right side of things that way. I use the C300 which is a really good camera, lovely image BUT lacks SO MUCH! and at $13k I really do not think it is justified.
They need another game changer IF they really want to stay in this game.
The GH4 it is only the beginning.
